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:Assembling process of clip type check valve: Among them, the stainless steel clip check valve belongs to this type of valve, which includes swing check valve and lift check valve. The swing check valve has a hinge mechanism and a gate like valve free against the inclined seat surface. In order to ensure that the valve can reach the appropriate position of the seat surface at any time, the disc is designed in the hinge mechanism so that the disc has enough swing space to make the disc real and comprehensive contact with the valve seat. The disc can be made of either metal or leather, rubber, or synthetic coverage, depending on performance requirements.

Q:Fire hood fire check valve okay?: The utility model relates to a fire fighting check valve for a range hood, which belongs to an innovative product and can be used.

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:What kind of check valve is used in the sewage pump of sewage treatment plant?: 3. to prevent hydraulic impact on the check valve sealing surface damage protection measures, check valve settings, to prevent the backflow of material, pump impeller to avoid the impact of the role of liquid. But as for the check valve itself, improper setting will cause a sudden impact of the disc on the valve seat by the water hammer, and damage the check valve sealing surface. Therefore, several protective measures should be taken. 1, for the pump outlet set >80mm swing check valve, horizontal installation should be adopted to weaken the valve seat back and the impact. 2, for the pump outlet check valve >=150mm diameter of the pipeline, should be placed before and after the bypass valve, to prevent the pressure before the valve rises too high, the check valve sealing surface damage. 3, the pump discharge pipeline starting and ending pressure is higher, the pipeline is not allowed to set the bypass, you can take the following measures. Set up safety valve instead of bypass valve. The action is similar to that of the bypass valve. It is located near the check valve outlet. When the water hammer causes the pressure to rise, a part of the water can be released to prevent the damage caused by the pressure rising. An air or inert gas buffer tank can be set. It is located near the check valve outlet, and when the water hammer is produced, the pressurized gas is compressed through the buffer tank to alleviate the pressure rise caused by the water hammer.

Q:What are the features of axial check valves?: Axial flow check valve (GB/T 21387-2008) by the standardization of the national valve technical committee (SAC/TC 188). The drafting unit: Shanghai Huatong Valve Co., Ltd., Ningbo aimeike copper valve valve Co. Ltd. Shanghai zhengfeng. Main drafters: Zhang Yonghui, Liu Tienan, Zheng Xuezhen, Chen Tiewang, Meng Aimin.

Q:Does the tap water return to the water?: The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium.

Q:Does FOTILE hood have check valve?: Therefore, it is necessary to install a check valve at the flue port.

Q:Is the check valve behind or behind the gate valve? Why?: Thank youPlease install it in frontWhat about the front?

Q:Butterfly micro stop type check valve HH46XP-10Q, what does the letter mean?: Do not know what you say is the manufacturer of valves, in general, many models are manufacturers themselves according to the specifications of their products set.

Q:How can the lift vertical check valve be distinguished from the lift horizontal check valve?: Vertical lift check valves and lift horizontal check valves are different in structure, type, appearance, including installation.Vertical lift check valve, also known as vertical check valve;Lifting horizontal valve check valve, also known as horizontal check valve.Lift check valve: check valve sliding along the vertical centerline of valve body, lift check valve can only be installed on horizontal pipe,Disc can be used in high pressure small bore check valve. The valve body of the lift check valve is the same as the cut-off valve (which can be used with the stop valve), so it has a large coefficient of fluid resistance. The structure is similar to the cut-off valve, the valve body and the disc are the same as the cut-off valve. The lower part of the upper valve and the valve cover processing guide sleeve, the valve in the valve lift free guide simple simple light driven, when the medium downstream, the valve by the media force open, when the media stopped flow, the valve by the self vertical landing on the seat, preventing the media from the upstream effect.Through lift check valve, the direction of inlet and outlet of medium is perpendicular to the direction of valve seat passage;Vertical lift check valve, the direction of its medium inlet and outlet passage is the same as that of valve seat passage, and its flow resistance is smaller than straight through.
