Slow return check valve (1)
TC
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. Thanks to the adoption of special notches,
it is superior in controllability when the
opening is small.
2. As this has opening indication scales, it is
superior in reproducibility.
3. As this is of in-line type by the thread
connection method, it can be assembled
easily.
