Product Overview

The 'GV'  Type Gauge Vent Needle Valve is designed for safe and reliable isolation, providing bubble-tight shutoff with a non-rotating, anti-galling tip and a dynamic self-adjusting spindle seal, ensuring long service life in various applications. The additional ability to bleed the gauge cavity to the atmosphere and connect a calibration device, via a ¼' NPT female connection, is included.

Oliver Valves Gauge Vent valves offer metal-to-metal seating and a small-bore isolation valve for various applications, while also providing the option to vent to the atmosphere.

The Gauge Vent valve is supplied standard with a non-rotating tip, allowing for linear closure while eliminating galling.

Oliver Valves’ standard Gauge Vent valves are rated at 413 bar (6,000 psi) but can be rated at 689 bar (10,000 psi). Standard Temperature range: 240 °C to 540 °C.

All NPT connection threads are Single Point CNC machined.

All Oliver products have material traceability and pressure test certificates in accordance with 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 standard, featuring back seating and anti-blowout protection, a major safety feature. An anti-removable steel pin is fitted into the body, preventing the head unit from being removed inadvertently.

The dust cap protects the spindle threads from the ingress of dirt and is colour-coded for a specific service.
