Swing check valve

Stainless steel swing check valve

There are two types of check valves: straight-through type and right-angle type.
The straight-through check valve is installed on the pipeline with a threaded connection.
Right-angle check valves have three forms: threaded connection, plate connection and flange connection.
The hydraulically controlled check valve is also called the lock valve or the pressure maintaining valve. It is the same as the check valve to prevent the reverse flow of oil. However, when the oil flow is required to flow in the reverse direction in the hydraulic circuit, the control oil pressure can be used to open the one-way valve so that the oil flow can flow in both directions.
