The 'M' Type Single Isolating Needle Valve is designed for safe and reliable isolation giving bubble tight shut off, non-rotating & anti-galling tip and dynamic self-adjusting spindle seal to give long 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 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.

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.
