Oil valve SWH-G02-D24-20 plate hydraulic check valve hydraulic solenoid valve

One-way valve is also called check valve or check valve. Used in hydraulic system to prevent reverse flow of oil flow, or in pneumatic system to prevent reverse flow of compressed air.

One-way valves are straight-through and right-angle. The straight-through one-way valve is installed on the pipeline by threaded connection. The right-angle one-way valve has threaded connection, plate connection and flange connection. Hydraulic control one-way valve, also known as locking valve or pressure retaining valve, is the same as one-way valve to prevent reverse flow of oil. But when the reverse flow of oil flow is needed in the hydraulic circuit, the oil pressure can be controlled and the one-way valve can be opened to make the oil flow flow in both directions. Hydraulic control one-way valve uses conical spool, so the sealing performance is good. This valve can be used as one-way locking to keep pressure when sealing oil pipeline is required. There are two ways to control oil leakage by hydraulic one-way valve: internal and external. Internal leakage type can be used in oil pipeline without back pressure at reverse outlet of oil flow; otherwise, it is necessary to use external leakage type to reduce control oil pressure.
