High Pressure Valve
UKL High Pressure Valves
are manufactured in Gate as well as Globe valve types.
UHPGTV – Gate Valve –are use
when an uninterrupted flow is required, Gate valves are specifically intended
for use in isolation applications.
UHPGLV – Globe Valves are
designed to close off, open up or throttle the flow in a pipeline.
The Pressure Seal Bonnet
Apart from the standard
Bolted Bonnet type in a gate/Globe the Pressure Seal Bonnet is adopted for
valves for high to very high pressure service. The unique feature about the
pressure seal bonnet is that the Body – Bonnet joints seal improves as the
internal pressure in the valve increases, compared to other constructions where
the increase in internal pressure tends to create leaks in the body-bonnet
joint.
Design
All valves upto 50 mm are
outside screw and yoke, welded bonnet type design, rising stem, renewable seat
for Gate valves. Globe valves will have integral seat.
Pressure seal bonnet
design valves are 50 NB & above outside screw and yoke type, rising stem.
Gate valves shall be with
flexible wedge type Gate. Globe valves shall have conical type disc.
