Triple offset butterfly valves are executed with a metal to meal seat designed to make sure best tightness in chemical, gas, steam, cryogenic and petrochemical applications. These valves are accessible in lug type, wafer type, and twin flanged type.

Triple-off set butterfly valves provide the top sealing and high life of all butterfly valve designs. Here are some of the factors they are chosen:

For the extreme situations of critical procedure applications, steam separation and temperature high, TOVs offer performance standard and reliability.

The bi-directional zero outflow closure with a metal seat, even after high cycling, offers sealing honesty previously linked just with soft-sealed control devices.

Small torque from quarter-turn action allows little actuator and affordable cost.

Key Application(s)

• Used as control and cut-off equipment for smelting, chemical engineering, sewage engineering, environmental protection system and control subsystems of water, power, and steel plants.

Design Features

• Sizes from NPS 2” to 48” (DN50 to DN1200)
• CLASS 150 to 2500 (PN20 to PN420）
• Operating temperature -196℃ to 593℃
• Compact structure, easy installation, and disassembly as well as repair friendly, RANGER TOVs are also lightweight
• It has a certain adjustment capability and can be used as a control valve.
• With the triple-eccentric structural design, the sealing face is separated as soon as opening, so the mechanical wearing and friction between two sealing faces are eliminated during the opening and closing of butterfly plate, the operation torque is lowered, and the service life is longer.
• Zero leakage
• A wide range of applications – triple-eccentric metallic sealing butterfly valves have a wide range of temperature, pressure, and diameter.
