OpEXL™ Eccentric Plug Rotary Control Valve

Eccentric Plug Rotary Control Valve like the OpEXL are sometimes called, have become an increasingly common choice for plant stakeholders due to, among others, their: capacity to handle high flows, superior rangeability, compact size, and shaft seal design.

The OpEXL is a robust, lightweight, and economical alternative to globe style control valves. It was designed to comfortably handle differential pressures up to 725 psi (50 bar), temperature ranges from -150 degrees F (-100 C) to 752 degrees F (400 C), in sizes from 1” to 14” and ANSI Classes 150 to 300.

It has broad rangeability at 160:1, which is significantly higher than most globe control valves (50:1), as well as most butterfly valves (20:1). The Trimteck-Optimux OpEXL has three available trim reductions for each size, which allow users to hone in on specific control parameters.

The seating design in which the plug cams into the seat eliminates friction and reduces the effects of abrasives, making for a much longer lasting valve in most any service.

    • 160 to 1 Rangeability/Turndown
    • Class IV & VI Available
    • Standard ISO Shaft and Mounting Pad compatible with multiple types of actuators
