Fire Fighting Dry & Wet Riser

Hydrant Valves are designed to 8.82060,8.8 5041,6.5 5041 Part2.

Inlet Flanged or threaded to international standards.

Outlet 65mm ( 2 1/2M ) female instantaneous. Full range of pattern including OBLIQUE, BIBNOSE and 30° to 90° types are available. Body made of gunmetal or brass with renewable hard composition rubber disc.

Chrome plated valves on request, valves are manufactured to class 200 rating or PN32 designation. Blanking caps and plugs supplied on request.

Regulator Controlled Pressure Hydrant Valves

Operation Both "E" type and Stanley type pressure regulators incorporates a spring loaded balanced pressure reducing valve combined with hydrant stop valve. Positive outlet pressure control is achieved by aventure section in the outlet flow away.

The pressure rise in "shut off" conditions is minimal under severe frost conditions, the regulator should be suitably protected to prevent any residual water in the regulator from freezing and adversely affecting its operation.

Applications Fire mains systems in high rise buildings, for high pressure systems on oil rig platforms and in oil refineries and chemical plants. In conditions where length of water mains lead to high pressure drop where low pressure conditions are produced by pump characteristics.

Pressure Range : Outlet : 4.1 to 5.5 bar,   5.5 to 8.3 bar,    Inlet : 4.8 to 20.7 bar.

Connections :
