Shimadzu check valve is a typical seat valve, also known as check valve or check valve. Used to prevent reverse flow of oil flow in hydraulic system.
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 threaded connection. Right angle check valve has three forms: threaded connection, plate connection and flange connection.
Hydraulic control check valve is also known as locking valve or pressure maintaining valve. It is the same as the check valve to prevent the reverse flow of oil. However, when the reverse flow of oil flow is required in the hydraulic circuit, the control oil pressure can be used to open the check valve so that the oil flow can flow in both directions. The hydraulic control check valve adopts conical valve core, so it has good sealing performance.
When it is required to close the oil circuit, this valve can be used as a one-way locking of the oil circuit to keep the pressure. There are two leakage modes of hydraulic control check valve control oil: internal leakage type and external leakage type.
Internal leakage type can be used in the oil circuit without back pressure at the reverse outlet of oil flow; Otherwise, an external leakage type is required to reduce the control oil pressure.
