BuTech Medium Pressure Valves are designed for liquid and gas flow control in petroleum, chemical, power generating and general industrial applications.

Available in a variety of body styles, the valves are designed for operation at temperatures ranging from -100° to +600°F (-73° to +315°C). Optional packings and/or extended stuffing boxes increase the range to -423° to +1200°F (-253° to +648°C).

Their rugged construction provides assurance of fail-safe operation at pressures ranging to 20,000 PSI (1380 bar).

Materials of Construction

Standard materials of construction include 316 cold-worked stainless steel, 17-4PH, Ampco 45, and glass-filled teflon. All BuTech equipment may also be produced in any machinable metal. Some of the more common exotic materials used are:

  • Hastelloy™
  • Inconel™
  • Titanium
  • Monel 400™

Tube Sizes: 1/4" through 1" ; Pressures to 20,000 PSI (1380 bar); Type: M/P Cone-and-Thread
