Hydrant valves

A full-flow hydrant valve is the connection point where firefighters can tap into a water source. Operating on full-on or full-off positioning, the valve has an adapter that is easily removed for seat adjustment.

Landing Valve ideally should be installed in all the floors of a building whereas hydrant valve is installed in the ground floor. In case of fire, the firemen connect their hose to the landing valve that supplies water to extinguish the fire. Landing valves are permanently charged with water using a pressurized supply.

The four-way valve is attached to a 2 ½-inch hydrant outlet, and the hose is attached to the proper port of the valve. ... As soon as the pump is in gear and the discharge gate opened, the handle of the four-way valve is turned 90 degrees thus diverting hydrant water from the hose line into the pump.
