A low differential check valve is provided for a fire control system, having particular adaptability in a dry system. The check valve is maintained in its closed position by a latch which is controlled by a plunger. The plunger is activated, and moved to release the latch, upon the sensing of drop in system air pressure by a higher differential mechanism external of the check valve. The check valve may then be reset, with its clapper moved to its closed condition, without requiring internal access of the check valve to release a clapper latch.

L'invention concerne une soupape de retenue pour un système de protection contre l'incendie pouvant particulièrement s'adapter dans un système à sec. La soupape est maintenue en position fermée par des moyens de verrouillage commandés par un piston plongeur. Le piston plongeur est activé et déplacé pour dégager les moyens de verrouillage, après détection d'une chute de la pression d'air du système par un mécanisme hautement différentiel, extérieur à la soupape de retenue. La soupape peut ensuite être ramenée à l'état initial, avec son clapet déplacé en position fermée, sans requérir d'accès à l'intérieur de la soupape pour dégager les moyens de verrouillage du clapet.
