Fire Safe ‘FS’ Type Needle Valve
Fire Safe ‘FS’ Type Needle Valve
The ‘FS’ 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. This enables a long service life in various high temperature and high-pressure applications and is supplied with the Firesafe testing to BS6755 PT2 / API607 / ISO10497 / API 6FA.
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 Fire Safe ‘FS’ Type 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 at 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.
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 significant safety feature. An anti-removable steel pin is fitted into the body to prevent the head unit from being removed inadvertently.
The dust cap protects spindle threads from ingress of dirt and is colour coded for particular services.
The valves engineered by our team perform reliably even after years of use in demanding industry applications. If you would like more information regarding our needle valves, please contact Oliver Valves today!
