What is the introduction of one-way valve

One-way valves are divided into two types, one is straight-through type and the other is right-angle type. 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 is also called lock valve or pressure retaining valve. High temperature fan is the same as one-way valve to prevent oil reverse flow. 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.
