Product Description:

Wafer Type Dual Plate Check Valve

Specification of Water Check Valve:

We manufacture top quality Wafer Type Dual Plate Check Valve made from cast iron, cast steel and stainless steel. Wafer Type Dual Plate Check Valves offered by us can be availed in various types like dual plate; single disc type and non slam check valves to meet the different requirements of the customers. We are identified as one of the celebrated Wafer Check Valves Suppliers in China.

Wafer body style fits between FF or RF flanges
Upper and lower PTFE thrust washers
Dual plate Valves give maximum strength with minimum opening time
Torsion springs assist Valve closure, preventing flow reversal
Thrust washer reduce friction and wear of Valve plate hinges

 

Features of Wafer Check Valve :

 

1. Small and light, tightly sealed. Less expensive than swing check valve.

2. Two torsion springs are used exerting on each of the pair valve plate, which close the plate quickly and automaticlly

3. The quick-close action prevents the medium from flowing back and eliminates water hammer effectively. 

4. Can be installed both horizontal and vertical on pipeline

5. Safe and reliable in operation, high interference-resistance.

Q:Does one-way check valve affect water flow?
The water inlet of the household water heater is equipped with a triangle valve, which will not affect the flow of water, and be convenient for maintenance and inspection
Q:Why can't the check valve on the air pipe be used when the wind speed is less than 8 meters?
First of all, you must understand the working principle of the check valve, indeed, as you said, you can adjust the position of the hammer by adjusting the position of the drop hammer.If you are in their own design and production, consider the thickness of the blade, drop hammer size, weight, and other parameters considered.Hope to be of help to you!
Q:Is the check valve in or behind the gate valve? Why?
Pump outlet, check valve, gate valve.Gate valve plays a regulatory role, is the main pipe. Such a sequence can ensure that the water flow during power failure does not cause damage to the gate valve.
Q:Why is the water ring vacuum pump equipped with check valves?
The check valve is a one-way valve, the instantaneous vacuum of the stopping pump is higher than the pump cavity, and the gas enters the pump cavity from the exhaust port, and the water pressure is connected to the vacuum pipeline, and the function of the check valve is to prevent water from entering the pipeline
Q:The role of the clip lift check valve
It only allows the medium to flow in one direction and prevent the flow in the opposite direction. Usually the valve is automatically work, fluid pressure flow in one direction, the valve open; the opposite direction of fluid flow by gravity, fluid pressure and valve closing effect on the valve seat, thereby cutting off flow. Check valves are generally applicable to clean media and are not suitable for media containing solids and viscosity.
Q:What's the difference between the cut-off check valve and the stop valve?
The principle difference between the check valve and the cut-off valve is that the non-return valve allows only one-way flow of liquid, allowing only one flow from one end to the other. It is a one-way valve, and the shut-off valve allows two-way flow. The biggest difference is the structure of the valve head and valve closing method is connected by the check valve is separated, the appearance of the cut-off valve import and export in a plane and the cut-off valve is a one-way valve, arrow shell stop check valve on the other.
Q:What type of check valve is the h61y-40 check valve?
Two, swing check valve: the valve swing check valve cylindrical disk-shaped, around the seat of the shaft for rotation channel, because the valve channel into a streamlined, flow resistance than the small valve lift check, suitable for large caliber occasions in low flow and no flow frequently change, but not for the pulsating flow, the sealing performance is less than lift. Swing check valve is divided into single, double, and most types of three, the three forms mainly by the valve bore points, the purpose is to prevent the media to stop flow or reverse flow, weakening the hydraulic impact. Three, compression type check valve: This valve is used as boiler water supply and steam cutting valve, it has lift check valve and stop valve or angle valve comprehensive function. In addition, there are - some do not apply to pump outlet check valve is installed, such as valve, spring-loaded check valve, Y type check valve check valve. Four disc check valve: disc check valve around the pin rotation in the valve seat.
Q:How do I install the pump outlet check valve?
Order note: 1. Pump outlet check valveProduct name and model number 2. Whether or not to take accessories for our correct selection. Use pressure. Use medium temperature.Two, if the company has been selected by the design unitPump outlet check valve type, please pump outlet check valveThe model is ordered directly from our sales department.Three, when the use of the occasion is very important or the environment is more complex, please try to provide design drawings and detailed parameters, by our valve company experts for your audit checks. If you have any questions: please call us for advice:,We will do our best to provide you with quality service.
Q:Can the flue check valve and kitchen check valve protect against odor?
Not really. It depends on what valve it is. If it is a variable pressure air valve, of course, if it is an ordinary other valves, generally only temporary role. Five residential home kitchen platoon smoke system is the application of this variable pressure air valve.
Q:Can the slow stop disc check valve close quickly?
Slow closing disc check valve does not turn off quickly."Slow closing" means slow closing and fast closing.The butterfly valve is mainly composed of a valve body, two semicircular discs, a return spring, an oil storage tank, a slowly closing small cylinder set, and a needle valve (a micro regulating valve). The principle relies mainly on the thrust of the imported medium and pushes the two discs smoothly.
