ÇEŞİT

This electrically or pneumatically controlled pressure-reducing deluge valve range offers two reset options: 77DE-EL-PORV-PR-MR with manual reset and 77DE-EL-PORV-PR with remote reset. The pressure-reducing function controls the outlet pressure of water supplied to the deluge line, combining water discharge and pressure management in systems requiring a rapid response. The valve has a GGG50 ductile iron body, ISO or ANSI flanged connections, a maximum operating pressure of 300 psi / 21 bar and a maximum operating temperature of 80°C. The 77DE-EL-PORV-PR uses a 24V DC, 3/2-way normally open solenoid, while the 77DE-EL-PORV-PR-MR uses a 24V DC, 2/2-way normally closed solenoid. Various sizes are available to suit fire protection project requirements.
