Dual Plate By Pass Type Check Valve

Bypass dual check valve, reducing valve, backflow check valve

By-pass valves are generally used for three basic reasons:

To allow the pipeline differential pressure to be balanced, lowering the torque requirement of the valve and permit one-man operation.

With the pump closed and the by-pass open, a continual flow is allowed, avoiding possible stagnation.

Delayed filling of pipelines.

The bypass valve produced by TVCCL is a dual plate wafer type check valve with a hand-wheel to adjust the water flow and achieve dredge effect. It is very simple to use the hand-wheel to control valve to open and close. The installation method is the same as the dual plate wafer type check valve. The only difference is the hand-wheel. The advantage of using the hand-wheel to control the pressure difference is that without external power, and the pressure of the system itself is actuated, which effectively improves the operational safety and more reliable than the conventional electric control valve. Also, the price of the bypass valve is lower than the electric control valve.

Dual disc check valves are commonly installed in applications that backflow would cause an issue. However, since they are non return valves, they are a cheap, effective, and easy solution to solve a potential issue.
All place install check valve while Pipe have control valve or pump. If fluid have to back upstream after it.
Under some situation which need to stop returning also backflow, at this point it can backflow through the bypass which on check valve, to regulating too much flow in a pipeline by backflow. E.g. Pool on roof.
Body with full rubber lined can effectively reduce disc's leakage probability for the corrosion of seawater. In addition, body can choose CI or DI material to decrease cost.
Back-up Line for Uses Such as Replacement of Equipment.

Features
  • By pass check valve can be fluid control and decompression,Especially if replacing an existing valve to avoid pipe modifications.
  • Bypass check valve can be used as a regulator when replacing equipment.
  • Bypass check valve increases safety and saves money with handwheel than the electric operator.
  • Retail acceptable.
  • Beautifully packaged.
  • Customized special valve.
Specification
  • Size: 2" ~ 24" (DN50 - DN1500)
  • Pressure Rating For ASME: 125# ~ 150# Suit For ASME / MSS / API Flange
  • Pressure Rating For JIS: 10K Suit For JIS Flange

  • Designed in accordance with API 594
  • (Other flange connection please contact Taiwan Valves Centre Co., Ltd.)
  • *Technical information is only for reference. Taiwan Valves Centre Co., Ltd. reserves the right to change without previous notice.
Applications
  • By pass check valve is suitable for waterworks.
  • If the fluid passing through the check valve need to returned to upstream, a bypass check valve will be a good choice.
  • The bypass valve can prevent oil from entering the fuel system, guarantee the normal lubrication of the entire engine.
  • Bypass check valve is also used in central heating systems to ensure that the heat sink is not over pressured or emptied
  • Check valves are available for applications with control valves or pumps. e.g. check valve or BY pass check valve.
  • Bypass valves are basically there to vent pressure, it can be substituted for slow closure type valve.
More Knowledge about TVCCL valve:

Bypass valves are typically used in two situations as follows:
1. Replace the equipment, the bypass valve is not only to maintain the flow of the medium but also has a certain fluid control function. Therefore, it can be used as a substitute for pressure reducing valve and steam trap. When the equipment is replaced, the bypass valve can be used as a backup valve. When the equipment such as pressure reducing valve and steam trap is damaged or needs to be replaced and repaired, they are isolated. Or close the main pipe and open the bypass valve to keep the device running.
2. Strengthening function, the bypass valve can be used as a pressure reducing valve and a steam trap to enhance the hydrophobic performance.

More Knowledge about dual plate check valve:

Bypass valve has adjustment function. Not only adjust pressure between upstream and downstream, has hydrophobic capability.Bypass valve, also known as the bypass differential pressure valve, has the function of regulating the differential pressure between the upstream and downstream and can be hydrophobic. Bypass valve automatically adjusts according to the pressure change of the medium and balances the pressure difference between the medium in and out of the channel, which helps to stabilize the pipeline operation. For example, pressure reducing valves, control valves and traps are usually equipped with bypass pipes. The valve installed on the bypass pipe is called a bypass valve. Bypass valve refers to a valve that is mounted on a bypass pipe but does not specifically refer to the valve type and construction.
