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, hydraulically­operated 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.

An interconnected activating control system directs fire main pressure to separate
Open-Valve loop and Closed-Valve loop components to provide local and remote
system operation of Model 100PM-4B (see Typical Application below). The
Magazine Sprinkler Valve remains closed by Closed-Valve loop when it relieves
control pressure. The Magazine Sprinkler Valve is opened when Open-Valve
loop applies control pressure. When control pressure is blocked by the
interconnected activating piping, the system is in normal condition and the
100PM-4B can be activated by PRPV or the Three-Way Manual Valves.

The 100PM-4B has special lower port (capped) to connect test fitting that adapts
to a fire hose connection. Test fitting directs fire water through hose to waste
while retaining dry pipe condition to magazine during system tests and personnel
training events. Unpressurized visual indicator mounted on cover gives valve
position at all times.
