DELUGE VALVE

Introduction to the Imen Tiar Deluge Valve

A main valve is required within firefighting systems that work with either water or foam, which is able to quickly open the current of the fluid, in the minimum amount of time, in order to initiate the firefighting operation. This important role is played by the deluge valve. Essentially, deluge valve is a control valve, which is specialised for use in the automatic extinguishing systems.

The Operation of the Imen Tiar Deluge Valve

The deluge valve is opened and closed via the only moving part of the valve: the special sealed reinforced rubber, regularly known as the diaphragm.

1. Closed state: the pressure (P1) behind the diaphragm is equal to the main pressure (P2) of the water flow. This leads to closing of the deluge valve.

2. Open state: through evacuation of water behind the diaphragm, the pressure is reduced. As a result, the pressure of the main water inlet causes the instantaneous opening of the valve and the flooding of water.
