Heavy Duty HD Type Needle Valve
The ‘HD’ Type Single Isolating Needle Valve is designed for safe and reliable isolation giving bubble-tight shutoff, non-rotating, anti-galling tip and dynamic self-adjusting spindle seal to give long service life in a variety of high temperature and high-pressure applications.

Overview
The Heavy Duty ‘HD’ Type Needle Valve is 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 also 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 Valves 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.
Valve 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 body so that the head unit cannot be removed inadvertently.
