BuTech Pipe Valves are available in a variety of body styles, the valves are designed for manual operation in 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).
Materials of Construction
Standard materials of construction include 316 cold-worked stainless steel, 17-4PH, Ampco 45, and glass-filled PTFE. 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™
