Usage of Wafer Dual Plate Check Valve
Wafer Dual Plate Check Valve is used in pure line and drain line in many professions such as industry, environment protection, water treatment, high-rise building etc. The check valve is wafer-style, butterfly plate is composed of two semi-circle plates, can be reset by force of spring. The sealing face can be made from ontology surfacing wear-resistant material and rubber bush. This material is widely used, excellent sealing effect.

- Q:What type of check valve should be installed before the suction pump?
- Self priming pumps are equipped with rotary, rotary or automatic type check valves.Check valve, also known as one-way valve or check valve, its role is to prevent the medium back in the pipeline. Pump water off the bottom valve check valve also belongs to class. Forged steel check valves two body cover to connect the design form: the first is the body cover bolt connection forged steel valve, connected by this form of valve, the valve body and the valve cover bolt connection, spiral wound gasket seal, the advantage of easy maintenance;
- Q:Check valves - check valves - what's the difference between one-way valves?
- 3, swing type: liquid in the valve straight through, relying on the pressure to open the side of the rotating valve flap, after the loss of pressure, the valve depends on the weight back, the reverse of the liquid pressure closed valve. Other one-way valves (check valves), such as the sewage check valve, air defense explosion-proof valve and liquid use of the principle of the check valve is very similar
- Q:Is the hdf41x 1.6Mpa a check valve?
- The hdf41x 1.6Mpa is a backflow preventer with a check valve that is stronger and more complex than the function check valve.Backflow preventer (backflow preventer) is a device that uses a check element to prevent backflow of water supply pipe.
- Q:The difference between slow closed valve and open the valve
- The difference is mainly that the opening and closing of the slow closing check valve depend on the external and external forces to perform the slow opening and closing (usually hydraulic cylinder or pneumatic cylinder). The swing check valve is opened and closed by the pressure of the pipe medium to complete the opening and closing (and the pressure of the pipeline).
- Q:Check valve note BC/PISTON: SPR-L what does that mean?
- BC==Bolted Cover/ bolted bonnetPISTON== lifting typeSPR-L==Spring-loaded/ is loaded with springsTogether, it is: a spring-loaded check valve. Bolted bonnet (this is common)
- Q:What are the differences between the vertical check valve and the horizontal check valve in function and principle?.
- The check valve has a baffle inside it, usually closed by gravity,The function and working principle are basically indistinguishable
- Q:What is the function of the check valve installed in the water meter before entering the residential water?
- Generally installed after the water meter. The main reason: if the water point is higher than the water meter installation position, once the pipe network in the absence of water, the remaining water in the pipeline will flow in the direction of the water meter in turn. This will cause the water meter to reverse and cause damage to the water meter. A check valve is installed after the water meter, so that the situation can be avoided.The main function of the check valve is to prevent the backflow of the medium, prevent the reverse of the pump and drive motor, and release the container medium. The check valve can also be used to provide a supply to the auxiliary system where the pressure may rise above the system pressure.
- Q:Check valve H41T-16. What are the numbers and letters in it?
- H stands for check valves, 4 for flanges, 1 for lift, T for seal, and 16 for pressure
- Q:Can the slow stop disc check valve close quickly?
- At this point, the valve will automatically close under the influence of the spring and the medium return. However, as the piston rod is in an extended position, the valve can not be closed all the way, and there is about 20% of the area left to make the medium pass, so as to eliminate the water hammer. The disc is divided into two parts by the piston, which is fast, slow and slow. It can not only prevent the motor from reversing, but also eliminate the mute effect.
- Q:PPR check valve, butterfly valve, as well as water gauge which quota?
- The valves and water meters installed in the same pipe are the same
We mainly produce various check valves (for example,single disc swing check valve,double disc swing check valve,ball check valve,lift check valve, butterfly valves,diaphragm valves ,ball valves and so on).
