Delivering the longest life and most reliable performance for pressure control systems in severe environments.

Designed to meet the critical requirements of today’s most severe applications while ensuring the highest quality and most reliable performance for pressure control, BuTech valves and system components are available in any alloy to handle pressures from vacuum to 150,000 psi (10,340 bar) and temperatures from -423° F (-253° C) to over 1200° F (649° C).

  • Low Pressure Equipment Compression Fittings for Service to 15,000 psi (1,034 bar)
  • Medium Pressure Equipment Coned and Threaded to 20,000 psi (1,380 bar)
  • High Pressure Equipment Coned and Threaded for Service from 30,000 psi (2,070 bar) to 150,000 psi (10,340 bar)

BuTech Low 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 15,000 PSI (1030 bar).

Note: BuTech Pressure Systems does not recommend compression sleeve connections below 0°F (-18°C) or above 650°F (343°C).
