- Q: Why use special flanges for butterfly valves?
- Mainly for clip type butterfly valve sealing ring on the valve body than the ordinary flange chip small diameter. Therefore, the ordinary flange can not guarantee the effective sealing effect. Therefore, you must use a dedicated butterfly flange sheet
- Q: Why anti condensation of aluminum alloy anti condensation butterfly valve?
- Anti condensation butterfly valve multi-level unique progressive contact seat design, the valve plate in close contact in the process of gradually seat, ensure good sealing performance while reducing unnecessary torque, and the butterfly plate of stainless steel and the inner parts, thereby prolonging the service life of the valve seat, has strong rust and corrosion function. Torque reduction enables the drive to be lightweight and miniaturized. Unique stem seal prevents fluid leakage.
- Q: 1st where is my zone valve? I have an old Burnham gas baseboard heater2nd What do I do?My last resort is calling a proffesional.
- USA If you do not know where your valve is, you could not have tested it. How do you know it is not functioning? It might be that the electric signal required to operate the valve is not getting to the valve. Most zone valves can be opened and closed manually, if you want the heat constantly on or off. If you do not know where the valve is, or what to do with it, I strongly recommend you contact a licensed professional HVAC contractor.
- Q: In the pipeline attached building Atlas 05S502, in the middle of a water meter and check valve, the two sides are divided into two butterfly valve, want to ask why to arrange this way, what is the role of the two butterfly valve?
- Check the water gauge and check valve on both sides to facilitate the maintenance and replacement of water meter and check valve.
- Q: What is the effect of nylon coating on butterfly valve plate? Thank you
- Mainly media will not be contaminated by rust on the body, you should say that the central soft sealing butterfly valve, the central valve is generally cast steel or cast iron material, so useNylon coatingLining up. There are soft seals, sealing performance is relatively high
- Q: What does the triplex of pneumatic butterfly valve mean?
- Upstairs is quite right, but now seems to use very little oil mist, and now generally referred to as "triple parts" as if: filter pressure reducing valve, solenoid valve, with the valve position feedback switch.
- Q: 19 years ago i had a valve repair and now im due to have heart valve replacement. I heard that the metal valve make noise has anyone who has had the metal valve have this type f problem or any other problem with the metal valve it would be a great help if anyone could answer
- Do you want to have kids or have more kids? This is going to be the biggest question you have to answer. The tissue valve will require no treatment after the replacement, other than another replacement in 10-15 years or whenever the valve starts to fail. The mechanical valve will most likely last the rest of your life, but will require the use of anticoagulants that would make any future pregnancy extremely risky. As to the sound many patients complain about hearing the valve clicking in times when it is very silent (dead of night etc.) Most find that keeping a Radio or tv on at a low level solves the problem, Id say in my experience about 50% of patients complain about hearing the clicking. The other issue is that using tissue valves, it is a slightly riskier operation every time you re-open someones chest, due to scar tissue formation. So instead of say 1-3% risk it might be 5% if the person is young and healthy. This is important since the tissue valve will only last 10 maybe 15 years. The atrial thrombus complicates matters, however which valve are they replacing? It might be possible to remove the thrombus at the same time as doing the valve. If not, mo matter what you will be taking warfarin, so the vavle choice really will not matter that much.
- Q: What is the D37-10Q butterfly valve?
- It may be the D371, the turbine to the clip type soft sealing butterfly valve, from your model can also see that the pressure is 1.0MPa, the body is ductile iron. It could be the D373, the turbo clamp hard seal butterfly valve, which is more expensive than the soft seal.
- Q: What is the difference between the installation and function of a butterfly valve and butterfly valve?
- Therefore, the fully open position of the valve is determined by the position of the gate. Some gate valve, stem nut is located on the gate, the handwheel rotates to drive the stem to rotate, and make the gate lift, this kind of valve is called rotary bar gate valve, or call dark rod gate valve. The type of gate width, sealing surface configuration can be divided into wedge gate valve and parallel gate valve, wedge gate type valve can be divided into: single gate type, dual gate plate and the flexible gate type; parallel gate type valve can be divided into single and dual gate gate plate. According to the thread position of the valve stem, can be divided into two kinds of open rod gate valve and dark rod gate valve. Valve installation and maintenance should pay attention to the following: hand wheel, handle and transmission mechanism are not allowed for lifting, and is strictly prohibited. Double gate valve should be installed vertically, that is, the valve stem is in a vertical position, and the handwheel is at the top. The gate valve with bypass valve shall be opened before opening to balance the pressure difference between inlet and outlet and reduce the opening force. The gate valve with drive mechanism is installed according to the instruction of the product instruction. If the valve is constantly switched on, lubricate it at least once a month. The valve has the advantages of small fluid resistance, the sealing surface by the erosion of small and medium Chong brush. Opening and closing is more labor-saving. Medium flow direction is unrestricted, no disturbance, no pressure reduction. The utility model has the advantages of simple shape, short structural length, good manufacturing technique and wide application range. Valve faults between the sealing surface can lead to erosion and abrasion, maintenance more difficult. Larger size, open need a certain space, long opening and closing time. Complex structure.
