Cla-Val 81PM-1 - Manual

Hydraulically Actuated Check Valve
Typical Application
• Drip-Tight Shut-off
• Reliable Diaphragm-Actuation
• Remote Control Operation
• Ensures Proper Loop System Operation
The Cla-Val Model 81PM-1 Hydraulically-Actuated Check
Valve is designed for use in the Hydraulic Activation portion of
a shipboard Dry Type Magazine Sprinkler System. The 3/8”
81PM-1 is spring-loaded to close and requires control
pressure to open. The 81PM-1 Hydraulically-Actuated Check
Valve is a remotely-controlled diaphragm-actuated pilot control
valve used in interconnected activating piping to control
transition from Open-valve loop and Closed-loop operating
Magazine Sprinkler Valve. Control pressure signal is applied
in conjunction with 100M-1KR Remote Control Valve. When
control pressure is applied 100M-1KR Remote Control Valve
closes and 81PM-1 Hydraulically-Actuated Check Valve opens
allowing the Magazine Sprinkler Valve to remain controlled by
Closed-valve loop. When control pressure is relieved the
100M-1KR opens and the 81PM-1 closes and the Open-valve
loop activates the Magazine Sprinkler Valve. When control
pressure is blocked, the system is in normal condition and can
be activated by PRPV or Three-Way Manual Valves.
