CLA-VAL 403-11e (HS) : Pneumatically Operated Deluge Valve
The CLA-VAL 403-11e Remote Control Deluge Valve is used where "on-off" control is required. Pressure signals from a remote control "open or close" a small auxiliary valve installed on the main valve cover, which in turn opens or closes the main valve. Only the small amount of fluid in the auxiliary valve cover must pass through the remote control pilot in order to fully open or close the larger main valve.
