Our Products
OCV 68 DE\EL-MR - Electrically Actuated, Manual Reset Deluge Valve 2/2 Solenoid
Electrically controlled, deluge/pre-action valve, actuated by the pipeline pressure. The valve is closed in its normal, set position and opens when a 2w solenoid valve is energized. The valve must be manually reset following automatic actuation. An emergency manual release valve is fitted as standard.
UL Listed under VLFT category
ABS Type Approval
Lloyd’s Register Approval
ANSI FCI 70-2 Class VI seat leakage class
Fire tested to EN ISO 6182-5:2006 (2”-6” only)
– High pressure (PN25/375psi), high flow deluge systems
– Automatic or local manual emergency actuation
– Hazardous, flammable & explosion classified area fire suppression
– Superior design featuring exceptionally low pressure losses at high flow rates
– Low lifelong maintenance costs due to straightforward design
– Applicable for fresh or brackish water, seawater & foam
– Out of box fully assembled & tested valves
– Factory trimmed for vertical & horizontal installations without modification
– Extensive valve & trim materials selection
OCV 68 DE\EL\PR Electrically Actuated, Pressure Reducing, Remote Reset Deluge Valve 2/2 Solenoid
Electrically controlled deluge/pre-action pressure reducing valve, actuated by the pipeline pressure. The valve is closed in its normal, set position and opens when a 2w solenoid valve is energized. When tripped, the valve regulates to a steady, preset downstream pressure, regardless of upstream pressure or flow rate fluctuations. It closes drip tight when the solenoid valve is de-energized. An emergency manual release valve is fitted as standard.

OCV RCL 28-2UL 2-Way Relay, Manual Reset Latching Device
A 2-Way, spring-loaded, manual reset latching device, applicable for service on deluge and pre-action valve trims. In its “Ready” position, it prevents draining of the deluge valve’s control chamber, keeping the deluge valve closed. Once the deluge valve is actuated, the RCL 28-2UL shifts to its “Latched Open” position, allowing draining of the control chamber and latching open the deluge valve. Manual resetting is accomplished by rotating the RCL 28-2UL’s knob
