The Fisher HPT High Temperature Control Valve is engineered for demanding industrial applications that involve high-pressure, high-temperature fluid control.
Designed by Emerson Fisher, this advanced valve provides excellent performance, durability, and reliability in extreme thermal environments such as steam, hydrocarbon, and chemical processing systems.
The HPT series combines Fisher’s proven control technology with precision-engineered materials that ensure stable operation and tight shutoff even under severe service conditions.
High-Temperature Resistance
Specially designed for temperatures up to 1200°F (650°C), ensuring stability in steam and hot hydrocarbon service.
Robust Body Construction
Made of high-grade alloy or stainless steel, providing exceptional strength and corrosion resistance for long operational life.
Tight Shutoff Performance
Metal-to-metal seating design ensures reliable sealing under high thermal stress, minimizing leakage and improving process safety.
Versatile Trim Options
Available with various trim styles — including cage-guided, balanced, and multi-stage trims — to meet specific control needs and reduce cavitation or noise.
Actuator Compatibility
Fully compatible with Fisher pneumatic, electro-pneumatic, or smart digital positioners such as the Fisher DVC6200 or Foxboro SRD991, enabling precise flow regulation.

The Fisher HPT valve controls fluid flow by adjusting the position of an internal plug relative to the seat ring.
Its cage-guided design stabilizes the plug and maintains precise positioning even under extreme temperature and pressure variations. When paired with an intelligent positioner such as Fisher DVC6200, the valve achieves high responsiveness and accurate flow modulation across a wide range of operating conditions.
