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.

Check Valve Factory

Q: My house is public flue, a total of six floor I live five floors, with the side suction hood, hood in the windy outside started as soon as the check valve pops ring from occupancy, have what way?: The hood check valve is in two halves of plastic. It is too light and the wind vibrates. You can add some things, as long as the soot blowing function is OK (try several times). Able to solve problems.

Q: What does the number 16 on the check valve mean?: This is the pressure level of the valve, which represents 16Kg, which is used for piping pressure less than this pressure.

Q: The check valve on the air pipe is installed in front of the fan and is there any difference in the back (direction is correct)?: Yes。Installed in front of the wind blowing, the top open check valveIt is difficult to install the check valve, which is installed on the rear by the force of air suction.

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: Only one is a soft seal and one is hard sealed: Not the same model. The rubber valve check is HC44X, and the swing check valve is H44H

Q: Tap water tank with vertical and horizontal check valve.: Look at your pipe installation position, if it is vertical, of course, the vertical check valve is good, if it is horizontal, of course, choose a horizontal check valve.The function of the check valve is to ensure the flow of the fluid in one direction. The moving parts are usually pressed against the seat to form a seal. Small pressure must be applied to moving parts to open the valve. Once opened, fluid power is generated to allow the valve to open or increase opening. Before the valve closes, fluid flow must stop. Fluid power generated by fluid flow prevents all valves from closing. The spring can be used or not to control the opening and to close it. Some check valves rely solely on gravity to provide closing force. Valves that rely on gravity must be installed according to the manufacturer's instructions. If horizontal pipes are laid, the slope of a short distance local pipe must be changed.The swing check valve is powered by gravity. When the valve is opened, the force required to control the valve opening is increased. If the balance between disc weight and fluid dynamic force is incorrect, the valve will not be fully opened. Increasing flow speed may cause unexpected corrosion or erosion damage, so gravity driven valves must be used to meet operating conditions.When the valve is fully opened, the disc or piston stroke must be limited by the stopper. Fully open valve, but not limited, the valve is easy to vibration. Vibration may cause hinge pins or pistons to wear rapidly. Valves using springs may suffer from early spring faults (caused by fatigue). Vibration may be caused by vortices or disturbances. When the fluid has some viscosity, the fluid damping can control the vibration. Valves with springs may be fitted with different rigid springs. If the full stroke stops, including extrusion, to prevent backlash after rapid opening, this can be an effective vibration damper.

Q: How much is the check valve for the concrete pump?: 31 concrete pump price ranging from 15W to 60W, different configurations have different prices, which one do you want?

Q: Swing check valve can prevent any sewer defection: Check valves belong to the automatic valve, mainly used for one-way flow of media channels, allowing only medium to flow in one direction, to prevent accidents. This kind of valve should be installed horizontally in the pipeline.

Q: For home use, self suction pumps are installed outside the well and pumped into the water tank.Please check with the self-priming pump function (check valve, water valve)? If not, is not installed in the pipeline connecting wells and pumps? Thank you。: Both, but there are good or bad points, good seal, with a spring, the general is a piece of rubber plus a piece of iron, plus a check valve is feasible

Q: Does the Vatti range hood e601a2z have check valves?: As long as the regular manufacturers of smoke machines must be equipped with check valves, Vatti as a well-known brand of kitchen electricity, this should not worry about you
