High Pressure Valves


High pressure valves, or known as one type of quarter turn valve is quite literally a ball placed in a passageway through which fluid flows. The ball has a hole through it, by which the valve opens and closes. When the ball is positioned so that the hole runs the same direction as the passageway, the fluid simply flows through the hole, and the valve is open. However, when the ball is positioned so that the hole is perpendicular to the passageway, the fluid cannot pass through, and the valve is closed. The ball is controlled from outside the valve, often with a handle that is turned 90 degrees, or a quarter turn, back and forth to open and close the valve.

The basic ball valve, described above, is a two-way valve. This ball valve has a single, straight passageway bored through the ball, making two openings: one on each side, an inlet and an outlet. These high pressure valves are solution for liquid, gas, or air for applications like packaged power systems, portable test carts, or ultra high pressure water blasting. With high quality stainless steel construction, the ball valves are a good choice for applications like cleaning offshore platforms or vessel paint stripping where high pressure is required, and effective and reliable high pressure valves are needed for safety when controlling fluids.  Use these in conjunction with tubing and fittings rating up to 21,000 PSI.


  • 316 L Stainless Steel – For excellent corrosion resistance especially in harsh marine environments.
  • Metal to Metal Seating – Achieves tight shut off and seat life, greater durability for repeated open and close cycles.
  • Carbon Packing with Metal Backup ring – for reliable stem and body sealing.
  • Non-Rotating Stem – Prevents stem to seat galling.
  • Rolled Stem Sleeve  - Assuring smooth operation
  • Weep Holes  - For safety in all pressure connections and packing area.

High Pressure Valves

2 Way Ball Valves – Pressure Up to 21,000 PSI

2-Way Ball Valves have 1/4" orifices and are capable of safe handling of liquids and gases up to 21,000 psi pressure. Their 90° handle rotation allows for full flow capabilities with minimal pressure drop. Robust one-piece trunnion style stem design on these high pressure valves eliminate shear failure that is found in a two-piece stem design. Ball seats are made of Torlon material providing excellent sealing capabilities with low handle operating torque. Re-torqueable seat glands provide longer valve life and dependability. Standard valves are supplied with Viton O-Rings rated to 300°F

  • Pressure: 15,200 – 21,000 PSI
  • Max Temperature: 300 Degrees F
  • Seals: Viton O-rings for  High Temperature
  • Construction:  316L Stainless Steel
  • Certification:  ISO 9001:2000
