High Pressure Needle Valves | Maxpro Technologies

Exceeding the industry standard of 60,000 psi, Maximator® high pressure needle valves feature stainless steel, metal-to-metal seats and can be used with either gases or liquids.

Top rated for pressures to 65,000 psi, our needle valves have a high level of safety and reliability under adverse operating conditions. Traceability is ensured through extensively documented data, including batch number, maximum pressure, material number and type designation.

We offer a large selection of 2-way and 3-way high pressure valves available with 1/4, 3/8 and 9/16" O.D. and 4HF, 6HF and 9HF high pressure connection types, respectively. Select one of the options listed below for information on the specific needle valve styles. All high pressure valves include glands and collars.

Additionally we offer specialty packing for valves that must operate in extreme temperatures from -423 F to 1200 F. Please consult a MAXPRO® representative about this type of specialty packing.

MAXPRO® offers a complete line of high pressure components, including low and Ultra-High pressure needle valves.
