Description Yunyi stainless steel pneumatic one-way valve
The one-way valve is that the fluid can only flow along the water inlet, but the medium at the water outlet cannot flow back, commonly known as a one-way valve. One-way valve is also called check valve or check valve. Used in hydraulic systems to prevent reverse flow of oil flow, or used in pneumatic systems to prevent reverse flow of compressed air. There are two types of check valves: straight-through and right-angle. The straight-through check valve is installed on the pipeline with a threaded connection. Right-angle check valves are available in three forms: threaded connection, plate connection and flange connection.
