Slow return check valve (2) Flange connection type Hydraulic symbols A B Slow return check valve (2) 3-12 Overview This slow return check valve, in which a check valve is assembled into the variable throttle valve, can restrict the flow in one direction and allow the flow in the opposite direction to pass freely. Features 1. As this is a needle valve, fine adjustments can be made. 2. The throttle opening can be adjusted even during operation by turning the adjust thread. 3. As a lock nut is installed, there is no change in the throttle opening by vibration of the pipe during operation.

Overview<br />
This slow return check valve, in which a<br />
check valve is assembled into the variable<br />
throttle valve, can restrict the flow in one<br />
direction and allow the flow in the opposite<br />
direction to pass freely.<br />
Features<br />
1. As this is a needle valve, fine adjustments<br />
can be made.<br />
2. The throttle opening can be adjusted even<br />
during operation by turning the adjust<br />
thread.<br />
3. As a lock nut is installed, there is no<br />
change in the throttle opening by vibration<br />
of the pipe during operation.<br />
