CLA-VAL 100PM-4B : Magazine Sprinkler Valve
The Cla-Val Model 100PM-4B Magazine Sprinkler Valve is designed to deliver fire main flow to a protected space in a shipboard Dry Type Magazine Sprinkler System. The 100PM-4B is a globe-pattern, diaphragm-actuated, hydraulically-operated remote control valve with integral test port and visual position indicator. The 100PM-4B is held normally closed by a large spring load and internal hydraulic leveraged design feature for a dry pipe to magazine until valve is opened. When fire main pressure signal is directed to valve control port, the 100PM-4B opens quickly to allow fire main flow into protected space.
