Rated to different pressures and temperatures, we work with our customers to ensure that our Valves fit into both new and existing projects.


Oliver Valves needle valves provide the user with a 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 none rotating tip to allow linear closure while eliminating galling.

Oliver Valves' standard needle valves are rated to 413bar (6,000psi), but can be rated at 689bar (10,000psi) with a top-end of up to 1034bar (15,000psi). The range of pressures allows our customers to benefit from a wide range of needle Isolaton valves which are suited for a specific purpose. Our Needle valves are also available with both male and female threaded and welding connections in a range of different materials.
