Oliver Valves needle valves provide metal
to metal seating and small bore isolation valve for many applications without
having to resort to larger and more expensive globe valves.
The needle valve is supplied as standard
with a non rotating tip to allow linear closure while eliminating galling.
Oliver Valves' standard needle valves are
rated to 413bar (6,000psi), but can be rated at 689bar (10,000psi). Standard
Temperature range from 240 Deg C up to 540 Deg C.
All NPT connection threads are Single Point
CNC machined.
All Oliver products have material
traceability and pressure test certificates to BS EN 10204 3.1. A unique code
is stamped on all valve bodies linking them to their material and chemical
analysis certificates.
Tips are ‘interchangeable’ without special
tools or spindle changes in options of hard, soft and metering tips.
Safety – spindles are ‘back seating’ and
‘anti-blowout’ as standard, a major safety feature. Also ‘anti-removable’ steel
pin is fitted into body so that head unit cannot be removed inadvertently.
Dust cap protects spindle threads from
ingress of dirt and is colour coded for particular service.
