High Pressure Check Valve - O-Ring Type

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.* Pressure & Tube size Pressure(psi) kg/f bar Tube Size 5500 386 379 1/2" 7500 527 517 3/8" 11000 773 758 1/8" 11500 808 792 1/4" 20000 1406 1378 1/4", 3/8", 9/16", 3/4", 1" 30000 2109 2068 1/8", 1" 60000 4218 4136 1/4", 3/8", 9/16" 100000 7030 6894 1/4"* As all sizes are for reference, they can be different from actual sizes.* Please contact us for details or send to online inquiry, We will give you respond as soon as possible.* Body typesAs 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. * O-ring type check valve series 11500psi 20000psi     30000psi 60000psi       100000psi  * Our high pressure check valve series* Other product High pressure needle valve   High pressure pipe needle valve High pressure check valve   High pressure ball valve High temperature valve   High pressure control valve Air operated valve   High pressure tube fitting High pressure tube   High pressure nipple High pressure regulator   Back pressure regulator High pressure female adapter   General pressure regulator High pressure adapter   High pressure male adapter High pressure tube support   Radiating pipe* 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.for more details, please contact us.
