Diaphragm valve DV-5A

electricthreadedflange

Overview
The DV-5A deluge valve features a diaphragm-style design with external resetting capability, allowing system reset without opening a valve handhole to reposition a clapper or latch. Properly pretrimmed, the valve's double-seat arrangement enables fire alarm actuation upon system operation. Available actuation options include wet, dry and electric, with remote-reset and remote-reset/pressure-reducing variants.
