Inlet
: flanged or threaded to international standards.
Outlet
: 65mm
( 2 ½" ) female instantaneous. Full range
of pattern including OBLIQUE, BIBNOSE and 30O to 90O 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 sever 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.
