Electrically Actuated Manual Reset Deluge Valve DE RCL

Product code: DE RCL

Electrically controlled deluge/pre-action valve, actuated by the pipeline pressure. The valve is closed in its normal, set position and opens when a 3w solenoid valve is energized. The valve must be manually reset following automatic actuation using the RCL relay’s knob. An emergency manual release valve is fitted as standard.

OPERATION

The basic control valve [1] used in this deluge system is a direct-sealing elastomeric diaphragm, hydraulically operated control valve engineered specifically for fire protection systems. The system includes a 3/2-way N.O. solenoid [10] as the interface between the fire alarm control panel - monitoring heat, smoke or flames - and the deluge valve.

In the standby position, the deluge valve is held closed by the upstream water pressure, trapped in the valve’s control chamber. The water pressure enters the control chamber through the priming line ball valve [2], a Y-type strainer [3], a check valve [4] and a T-restrictor [5].

Under fire conditions, a fire alarm control panel (F&G panel) energizes the 3/2-way N.O. solenoid (or de-energizes the coil of a continuously energized ED 100% normally closed solenoid for SIL 3-4 rated systems). The pressure in the RCL 28-2UL relay valve (manual-reset latching relay) [9] drops, latching it open and allowing the water to drain the deluge valve’s control chamber. The deluge valve opens instantly and allows water to flow the pipeline and through the open sprinklers over the
protected area.

Manual emergency actuation is enabled by opening the emergency manual activation valve [6]. The deluge valve opens instantly and allows water to flow the pipeline and through the open sprinklers over the protected area.

To reset the deluge valve and close it, the RCL 28-2UL relay’s knob must be rotated to unlatch it, thus re-admitting water the valve’s control chamber
