Products Description of Swing Check Valve

Check valves are used in pipes under pressures between PN1.6~16.0MPa(Class150~2500Lb), working temperatures-196~600℃, They are used in industries include oil, chemistry, pharmaceutical, fertilizer, and power gene-ration to prevent the backward flux of the media.

The main structure features of Swing Check Valve:

1、The products feature a reasonable structure, reliable seal, good performance and nice modeling.
2、Either soft or hard seal can be selected for the product upon different working conditions.The sealing face is built up with Co-based
carbide alloy, leaving a better wearability, corrosion and scrap resistance and a longer duration.
3、Small opening pressure, the disc can be opened fully with a very small pressure differential.
4、Inside-set bolt-bearing structure reduces leakage and reliable use.
5、PN≥16.0Mpa (class1500), the middle cavity uses a self-tightening sealing structure to have the sealing performance reinforced along
with the pressure rise so as to ensure the sealing performance.
6、Different parts materials and different sizes for flange, butt-welding are available for sensible combination according to different working facts and customers' requirements.

FAQ of Swing Check Valve:

Q1:I can’t find the type of steel check valve which I need. what can I do?

The chart above only lists out some common composition of steel check valve parts.We may provide other different parts material composition according to the customer's request or the actual valve working condition.

Q2:Which certification do your products pass?

Our products are in accordance with ISO 9001、ISO 14001、API 6A、API 6D、TS CE、API607/6FA/BS6755.

Q3:How can I place an order?

The only one thing you should do is to tell us the sepecification about type 、quantity and mode of transportation, then we will send you quotation within 24 hours.

Q: We need to replace our erg valve, but we cannot locate it.: I have that very vehicle and have had to locate mine, it is on the passenger side of the engine towards the firewall and it has an 5 pin electronic connector (Mine is Black) on top of a dark grey to black colored cylinder next to the cover on top of the engine. But before you go through replacing it (as it is around $200 to $300 ) try cleaning it with spray type fuel injector cleaner and work the stopper inside in and out until it frees up. This will need to be repeated as the faulty item in my vehicle was an o2 sensor of which there are 4 located throughout the engine. So you will need to have a decoder to check and see which is to blame. Most parts stores will read it for free. Good luck. P.S. my o2 sensor cost about $60 for the part.

Q: ok, after lots of exploring around online and from some great answers from this site I have found the problem to my explorer. The torque converter solenoid mounting clip broke. thats it!! new question, do i have to take off the valve body to remove the solenoid. If so any tips? its way new territory for me. I hate automatics!!: Yes. REMOVAL Disconnect battery ground cable. Raise and support the vehicle. WARNING: THE ELECTRICAL POWER SUPPLY TO THE AIR SUSPENSION SYSTEM MUST BE SHUT OFF PRIOR TO HOISTING, JACKING OR TOWING AN AIR SUSPENSION VEHICLE. THIS CAN BE ACCOMPLISHED BY TURNING OFF THE AIR SUSPENSION SWITCH LOCATED IN THE REAR JACK STORAGE AREA. FAILURE TO DO SO MAY RESULT IN UNEXPECTED INFLATION OR DEFLATION OF THE AIR SPRINGS WHICH MAY RESULT IN SHIFTING OF THE VEHICLE DURING THESE OPERATIONS. Remove the transmission fluid pan, filter, and gasket. NOTE: If a transmission has been disassembled to replace worn or damaged parts and the valves in the main control valve body stick repeatedly from foreign material, the torque converter must be removed and cleaned by using a mechanically agitated cleaner, such as Rotunda Torque Converter/Fluid Cooler Cleaner 014-00028 or equivalent. Unclip main control valve body wire harness. - Lift up on wire harness guide and protector and disengage the retaining pins from the solenoid clamps. Disconnect the six solenoid electrical connectors. (1) Disconnect the SS1, SS2, SS3 and SS4 electrical connectors. (2) Disconnect the torque converter clutch (TCC) solenoid electrical connector. (3) Disconnect the electronic pressure control (EPC) solenoid electrical connector. Remove the manual control valve detent lever spring. (1) Remove the manual control valve detent lever spring bolt. (2) Remove the manual control valve detent lever spring. Remove the low/reverse servo cover bolts. (1) Remove the low/reverse servo cover bolts. (2) Remove the low/reverse band servo cover and gasket. Discard the low/reverse servo separator plate cover gasket. Remove the low/reverse band servo piston and rod. Do not remove the two (gold) bolts specified. CAUTION: Support the main control valve body. Remove the 23 main control valve body (black) bolts. CAUTION: Support the main control valve body. Remove the main control valve body.

Q: I live in Houston (where it hardly EVER freezes during the winter..) This winter it froze and the valve on the sprinkler system flew off and water started shooting straight up. Now that it's getting warmer and I'm going to need the sprinkler.. I have to repair it. Is this an easy fix that I can do myself? Or should I call someone.: Yes easy fix-- go to your big box store with the old valve-- so you get the right size and buy a new one less than $ 40.. chances are with the freeze the plastic parts cracked when the water inside froze---

Q: I somehow lost the valve cap to one of my tires. Do stores sell replacement caps? If so, would a place like Sears or VIP be a good place to look? If not, would a bike tire valve cap work?In the mean time, i took a cap off the fullest tire to put on this one(the lowest) was that good or bad idea?: Suggest that any tire store carries valve caps.

Q: I got new sprinkler valves put in (Rainbird anti-siphon kind). Every time a valve shuts off, it makes a loud squeak, kind of like plastic rubbing (NOT a bang like water hammering). Is this normal and will it go away? If not, what could be the problem? This is annoying because the sound can be heard in the house as it echoes through the pipes.: As the valve shuts down, the diaphragm will vibrate as the pressure changes from one side to the other, then it will Thump as it seals. This is normal. However, to isolate the squeak, you may check to see if there is a 1(backflow preventer installed, 2) (if built into the valves) the variable pressure screw on the top of the valve is set correctly. The variable pressure screw usually has a cross top handle (older ones had a dial) and should be set so that on a high pressure line, it shuts down fairly quickly. If this is open all of the way, it can cause the diaphragm to squeal by slowing the internal pressure change to shut it down.

Q: Also, Is a pneumatic control valve an ATC or an ATO; is it a FO or FC valve?: THere are a large number of types of valves; ball, gate, globe, needle, etfc. I suggest you look up valves on wikipedia. ATO = air to open; the valve has a pneumatic operator with a spring returning it to closed when the air pressure is removed ATC is the reverse FO = fail open; if the actuator fails the valve will be open. Actuators are made ATO, ATC, and air to move either way [no spring]. The latter would be your FLP. Control valves, by which I mean a proportioning valve or valve with a variable open area, with a 3-15 psi control input, are usually ATO.

Q: sprinkler valve leaking: Most valves are either 3/4 or 1 with female connections. Use the same size male adaptors with teflon tape wraped around the threads and screw it into the valves. Take a photo before you start to refer to when rewiring.

Q: I have replaced the rubber washer in the valve and when I pull up on the float arm everything seems to stop then shortly thereafter air bubbles start coming out of the bottom of the fill tube. How could air be getting thru the valve without water which would cause the shutoff valve to tighten?: This okorder /

Q: Sohc ZC (d15) honda I'm going to be painting my valve cover am I going to need new seals? What do I need to take it off and put it back on ? Please help I have the high temp sand paper all ready to go I just want to be ready: Valve cover gasket. Make sure it comes with the spark plug tower seals or you need to buy them separately. It's best to bead blast the cover before painting it.

Q: To control a double solenoid valve, what do you recommend to use in my PLC program .... Do you recommend to use the SetReset coils or to use the normal coils?: Cheaper and more reliable to use simple coils...You probably need to add a large transistor between PLC and coil, with a bypass diode, unless your PLC output can sink a LOT of current.
