ABSTRACT:
The valve is adapted to close against the force of a bias spring in response to a substantial increase in the pressure drop through restricted by-pass passages in the valve when a hose is ruptured on the outlet side of the valve. The restriction of the by-pass passages is adjustable by rotation of an internal adjustment ring to thereby determine the flow rate at which the valve is actuated.
