FAQ
Q: Do you produce valves with PN40?
A: Yes, but for PN40, we suggest materials of metal, like cast steel, stainless steel…etc. We could also produce ductile iron valves with PN40.
Q: Are you manufacturer or trading company? Which kind of valves do you supply?
A: We are a professional manufacturer of butterfly valves, check valve, non-return valves, gate valves, Y-strainer and so on.
Q: Will you do inspection before shipment? Whether Third Party Inspection is available?
A: We have a professional engineer team, so we can offer you the most professional technical support. All valves are tested twice before and after hammer pin to ensure its perfect sealing property and to make sure every valve is ok before ex-factory. TPI is ok but the clients should bear all fees.
Q: What kind of package do you use for these valves?
A: Valves from DN80-DN1400 will be packed in wooden boxes, but valves above DN1400 will be in wooden pallets. If you need wooden boxes for above DN1400, the price may be more expensive.
- Q:this valve used in the refinery.
- This is a 'Trip and Throttle' (T T) valve that is maintained in a 'Fully Open' postion during normal turbine operation. It is maintained open by a Hydraulic Control system that, should any of many shutdown conditions occur, the hydraulic oil will be dumped to its reservoir by the operation of a Solenoid valve, actuated by the shutdown signal, and the T T valve will immediately close, stopping the steam flow to the turbine speed control steam chest in a safe manner. The valve handwheel is then operated to ensure that the valve remains fully closed until the system is ready for re-start. The valve cannot be opened again until the shutdown condition has been rectified and the hydraulic system reset to restore the oil pressure to the valve. The valve however, can then only be re-opened manually and slowly until the turbine is brought to the 'Minimum Speed Control' Governor setting. When settled down at this condition and the steam chest valves are under the control of the Governor, the T T valve is swung wide open. This latches the valve in the fully open position until another shut down occurs,
- Q:I've been told that I need to replace a clogged expanssion valve on my '96 toyota camry.A friend said he would properly recharge the system if i replaced the parts needed .I can't ask him where it is because he's out of town for a little while. I also need to replace the drier ,but it's obvious where it is.Please help me.
- the expansion valve is usually located inside the line next to the accumulator/dryer. If you drain the system, and remove the accumulator, look inside the line that leads into it, and it should be stuffed in the line. If you see one inside the line, it is actually called an orifice tube, but has the same function as an expansion valve. Actually, expansion valves are usually used in large vans with a rear a/c evaporator unit. If it is an external valve it should be next to the accumulator as well. The purpose of this valve/tube is to create high pressure gas out of low pressure liquid freon. These usually become clogged with debris after the compressor's pistons break apart and contaminate the system. If you find little metal shavings in the tube, or valve, your compressor was either replaced at one time, or is bad now.

- Q:hello!I'm designing a floor cleaner and for a water release system i was thinking of using a ball valve, connected to an actuator,however i'm not fully sure what to look for, and although I can buy the actuator and ball valve together, I'm not sure how to connect it to a motor and battery?If anyone can help my with this I'd really appreciate it!!Thank You!!
- An actuator for a ball valve can use either compressed air or an eectric power source to drive a motor. Air actuated valves can operate very quickly and are a little cheaper but they require a compressed air source and pneumatic controls to operate. An electric operator uses a geared motor to operate the valve and are slower. Electric operators are more expensive but only require power and some switches to operate. See link for hook up details.... The motor is built into the actuator so its just a matter of mating the actuator up with the valve. It would be best to buy a complete unit with the actuator and valve already attached. These will cost at a minimum several hundred dollars. Using a ball valve may not operate fast enough nor give you fine control if your considering using it to control the cleaning fluid applied to the floor. Instead consider using a solenoid valve instead. These are smaller valves and operate very quickly by just adding or removing power. Not to mention these are much cheaper $25 to $100 on average.
- Q:Long story short, have a 2001 acura tl had a rough idle/ no start issue. figured out by disconnecting vaccuum from the throttle body the idle was fine with the TB pulling air through the disconnected hose port. The hose i disconnected leads to the purge valve solenoid. I removed it and it is closed (no air flow), restarted car with hose disconnected and solenoid still harnessed in (still closed). Just need more info on the function of this thing and what it should be doing.. Can i bench test it with +12V and ground on the two pins? Thanks in advance.

- Q:my friend needs a flap valve replacement. does anyone no how serious this is, i dnt wanna lose my best friend?!!!
- Its heart surgery, which is riskier than many other surgeries, but valve replacement is routine procedure. There's a variety of different procedures that are used and several different types of replacement valves. Some valves can be repaired and some need to be replaced. Repairs usually give a person a normal or nearly normal valve that will last forever. Valve replacements don't work quite as wells as repairs and they usually need to be replaced in a decade or so. Most people can have the valved replaced by threading a scope through the arteries or using tiny incisions, but some people require open heart surgery. My friend had one of his valves replaced with a valve made from a pig heart and he was only in the hospital one night, and back to work a week later.
- Q:also are those air flow limiting valves safe for the air pump to reduce the flow of air, I have one because the air bubbles are just way too many without one and it scares the fish away
- a check valve is to prevent back siphoning of water into the pump if you have a power outage or unplug the pump by accident. I'd suggest checking it by blowing through it the wrong way; if air does pass through get a new check valve (check new ones to be sure they don't limit airflow too much, and that the close in the wrong direction, many are cheap crap and don't work the day you buy them, so check them before you leave the store with it...note: same with thermometers, compare them with each other so you don't get the one that's crap) what you want is a normal air valve, they come in various configurations, one or more valves so as to run multiple airstones and to balance the airflow to each stone or ornament. You should not however just use the valve to limit airflow, as this damages the pump eventually. You can just let one of two valves bleed off a little air; however make sure another check valve is in the line from the tank to the valves or else you risk water coming out of that valve if it's lower than the tank water level.....You may want a smaller air pump or an adjustable one instead.
- Q:When i was 14 I was diagnosed with a moderate aortic bicusspid valve. I am now 19 at my first cardiologist appointment I was still at moderate. Three months later when i went back in I was rediagnosed with a severe aortic valve. I have every symptom, and I'm getting ready to have it repalced. My question is what am I to expect after surgery. Will i be able to work if not is there anything I can do to have some sort of an income comming in?
- There are minimally invasive approaches, and there are many different techniques of valve surgery and all valve replacements, with choices to provide each patient with the best possible treatment.The patient will normally choose, with their surgeon, the type of incision, the type of valve and the technique. Valve repair versus valve replacement, with coronary artery bypass if necessary. The choices will normally depend on the patient’s opinion, their health history, and their surgeon's opinion. After successful aortic valve replacement, patients can expect to return to their preoperative condition or better. Anticoagulation (blood thinners) with a drug like Coumadin may be prescribed for 6 weeks to 3 months after surgery for those with biological valves, and for life for those with mechanical valves. Once the wounds have healed, most patients should experience few if any restrictions to activity. A patient will require preventative or prophylactic antibiotics whenever having dental work, and should always tell a doctor about their valve surgery before any surgical procedure.

- Q:I think on old AC units They had a different valve than the shrader. It might be called a king? Anyway, I can't get my gauge to read the pressure. The needles don't move at all. How can I measure, refill this type of HVAC?
- Unless you are EPA certified, you have no business checking the refrigerant in old AC units. If you get caught, you could face a hefty fine.
- Q:large veins contain one way valves, which keep the blood flowing in one direction. why dont large arteries need similar valves?
- In depth answer is: The Arterial Valves The semilunar valves are mere membranous pockets, and have no tendinous cords attached to them; but on account of the extent of their convex attachment, when their free margin is made tense by the pocket being filled from the artery, the valves can only pass a given distance from the wall of the vessel and are thus held firmly in position. The force of the blood leaving the ventricle distends the vessel and pushes its wall away from the less elastic valve. When the force begins to diminish, the blood passes behind the semilunar flaps and raises them from the wall of the distended artery. The moment the current from the ventricle has ceased to flow, the pockets are forced back by the aortic blood pressure and bulge into the lumen of the vessel, so that the convex surface of the lunated portions of each valve is pressed against corresponding parts of its neighbors. Their union, which is accomplished by their overlapping to some extent, forms three straight radiating lines, and is a perfectly impervious barrier to any backward flow of blood
