Keystone Check Valve – Swing Type
Excellent alternative for controlling counterflow with high speed, since it has the closing spring on the outside as well as a counterweight that is calculated according to the flow pressure that is going to be handled.
In such a way that the closing speed can be controlled and in this way be a silent valve but mainly the closing control allows mechanical fatigue due to knocking.
