ABSTRACT:
A frangible element valve assembly including a housing having an inlet port and an outlet port connected by a fluid passage that extends through the housing; and an actuator selectively controlling fluid flow through the fluid passage being biased to a predetermined fluid flow control position by a spring member of the valve assembly. Frangible elements of the valve assembly oppose the spring member to temporarily prevent the actuator from assuming the predetermined fluid flow control position, and these elements include breakable members that are broken by an operator to allow the actuator to thereafter assume the predetermined fluid flow control position until selectively changed by the operator.
