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 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.
