Check Valve, a valve to prevent the reverse flow of liquid (gas), is designed to block the flow in one direction and to promote the flow in the opposite direction. A Ball or O-Ring is used for the sealing purposes to prevent the reverse flow for certain. Both gas and liquid can be used.



* Features

- 2-pattern sealing type. (O-ring type, Ball type).
- O-ring for easy replacement and ball replacement-type check.
- Excellent corrosion resistant.
- A valve using stainless steel 316 cold material for preventing reverse flow.
- A valve that facilitates one-directional movement by blocking the reverse flow of gas or liquid.
- Cone and thread connection to prevent gas or liquid leaking.

* Body types



As shown by the above image, when a liquid or gas flows into a flow direction (right direction), the spring is pressed by the flowing liquid and the oil passage is opened. In consequence, the fluid flows. If the fluid tries to flow in the reverse direction of the flow, the spring recovers its original shape and closes the oil passage, preventing the reverse flow of the fluid.

* Ordering option

- As our products are divided into pressures of 5,500~150,000psi, body type and port size, you can use them according to the specifications which you want to use.
- Our products generally are produced with STS materials, but they can be manufactured with other materials on demand so that various fluids and gases can be used.
- Please inquire with us about special materials apart from the above-mentioned materials, such as STS316, HC-276, INC600, INC700, Ti and Ni.
