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 60,000 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.

Features

N/A High Pressure Valves feature:
  • Rising stem design.
  • 316SS wetted parts for excellent corrosion resistance.
  • Metal-to-metal seating achieves bubble-tight shut-off, longer stem and seat life, greater durability for repeated open and close cycles.
  • PTFE and carbon packing with metal back-up rings offers reliable stem to body sealing.
  • Non-rotating stem prevents stem to seat galling.
  • Stem sleeve and packing gland materials have been selected to achieve optimum thread cycle life and reduced handle torque. All stem sleeve threads are rolled, assuring smooth operation.
  • Safety weep holes for all pressure connections and packing area.
  • Six different valve body patterns, with choice of vee or regulating type stem tip.
