Function and configuration
Throttle valve of type DV, DVP and check valve of type DRV, DRVP are flow control valves to adjust movement speed of actuators simply and exactly. These valve can also be used as shut-off valve when completely shut. The scale of triangle shows how large the flow is (The larger the triangle is and the greater the flow is ). At the same time, for resetting again, it can be restored to the preset position.
