ABSTRACT:
Self actuating valve systems for fluid line networks comprising a main valving stem (3) with a driving-to-close bias spring (14) which is blocked by a detent ball (15) from closure against a valve seal (8), the ball itself being held by a removable pilot stem biassed to such holding action by a spring (17), the force of which can be automatically overcome at emergency temperature use condition by high force action of a shape memory spring (21). The main valving stem is manually resettable and the shape memory drivable pilot stem and related drive system are manually testable. A plurality of such valve systems are distributed in a fluid flow network for isolating an emergency temperature rise (e.g., fire region).
