MAXIMATOR high pressure valves with metal to metal seats have a high level of safety and reliability under adverse operating conditions. These valves may be used both with gases and liquids.
Traceability is ensured through extensively documented data (batch number, max. pressure, material number, type designation). All high pressure valves include glands and collars.

Special Designs for Extreme Temperatures

N/A Special Designs for Extreme Temperatures
Standard valves are supplied with Teflon/Carbon packing and may be operated to 450°F. High temperature packing and/or extended stuffing box are available for service from -423°F to 1200°F by adding the following suffixes to catalog order number.
  • TG standard valve with teflon glass packing to 600 °F.
  • GY standard valve with graphite braided yarn packing to 800 °F.
  • HT extended stuffing box valve with graphite braided yarn packing to 1200 °F.
  • B standard valve with cryogenic trim materials and Teflon packing to 100 °F.
  • LT extended stuffing box valve with teflon packing and cryogenic trim materials to -423 °F.

High Pressure Valves feature

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.
