Butterfly Valves

The Triad Series 750 has a cartridge seat design to alleviate installation problems associated with the dove-tail-design (booted) seats. It has a phenolic backing that keeps the seat from shifting during installation, reducing tearing and fatigue. Precision machining of the disc and body allow the cartridge design to maintain a tighter disc to seat tolerance, providing a perfect low torque seal each and every time the valve is cycled.

Triad offers many choices of direct mount electric actuators. These actuators are worm gear driven, eliminating the need for motor brakes. They come standard with manual over-ride and large dial position indicator. They are available in all voltages both AC and DC and come standard with auxiliary limit switches, heaters and thermostats. Options include 4-20ma servo control,position transmitters and local/ remote control stations.

Triad offers direct mount rack and pinion pneumatic actuators that have double travel stops insuring precise seating of disc. These actuators are available in both double acting and spring return versions. The actuator is corrosion resistant inside and out. Available accessories include modular mount positioners, pilot solenoid valves and limit switch assemblies.
