YV33 Needle Valve Manifold

The ‘YV33’ Type 3 valve manifolds are designed for remote mounting to differential pressure transmitters, with separate isolation for LP and HP inlets plus equalising valve for simple calibration. Each needle valve head is designed for safe and reliable isolation, giving bubble-tight shutoff, with non-rotating, anti-galling tip and dynamic self-adjusting spindle seal to give long service life in a variety of service conditions.

Oliver Valves YV33, Threaded x Threaded, type 3-valve manifold is designed for remote mounting to differential pressure transmitters, with separate isolation for LP and HP inlets plus equalising valve for simple calibration, while providing the option to vent to atmosphere.

The YV33 type 3-valve manifold is supplied as standard with a non-rotating tip to allow linear closure while eliminating galling.

Oliver Valves’ standard YV33 type 3-valve manifold 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.

Products that Oliver Valves have developed 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 significant safety feature. Also, an ‘anti-removable’ steel pin is fitted into the manifold body to prevent the head unit from being removed inadvertently.

The dust cap protects spindle threads from ingress of dirt and the needle valve manifold’s cap is colour coded to show the type of service condition.

The team at Oliver Valves have invested time and effort into the research and development surrounding the Needle Valve Manifolds to achieve the required results when testing for extreme applications.
