Angle ‘A’ Type Needle Valve
Angle ‘A’ Type Needle Valve
The ‘A’ Type Single Isolating Needle Valve is designed for safe and reliable isolation. The design provides a bubble-tight shutoff, non-rotating, anti-galling tip and dynamic self-adjusting spindle seal for extended service life in a variety of applications.
Oliver Valves needle valves provide metal to metal seating and small-bore isolation valve for many applications without having to resort to more extensive and more expensive globe valves.
The Angle ‘A’ Type Needle Valve is supplied as standard with a non-rotating tip to allow linear closure, which will eliminate galling.
Oliver Valves’ standard needle valves are rated 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 ‘anti-blowout’ as standard, a major safety feature. An anti-removable steel pin is fitted into the valve’s body to prevent the head unit from inadvertently being removed.
The needle valves’ dust cap protects spindle threads from ingress of dirt and is colour coded for particular services.
