Control Valves

OpGL™ Globe Control Valve

Reliable. Rugged. Economical.

Optimux globe control valves provide superior performance while permitting easy, fast, and inexpensive maintenance. Unlike diaphragm-operated control valves, the Piston cylinder-actuated OpGL™ provides stiffness, maintains high positioning accuracy control – making for the world’s most efficient and accurately responsive valve.

OpDX™ Butterfly Control Valve

Pressure-assisted seating achieves bi-directional shut-off and low breakout torque.

The OpDX™ butterfly control valve is a high performance rotary valve with an eccentric cammed disc that ensures accurate throttling. Its same flangless body (wafer) serves ANSI classes 150, 300, and 600 in 2″, 3″, 4″, 6″ and 8″ sizes. With our piston and cylinder actuator, this butterfly valve has greater flow capacity than any globe, plug, and cammed control valve.

OpVEE™ V-Notch Valve

Rugged enough for hard-to-handle and particle-entrained processes.

The OpVEE™ was designed to be used in a wide range of applications, including: chemical, pulp & paper, power, and petroleum services. It has solved many long-standing valve-related challenges, such as tensions in piping that unevenly load the seat, small ranges due to limited orifice characterizations, and unsatisfactory shutoff capabilities. Its integral flanges design standard and piston cylinder actuator deliver plenty of thrust for high performance throttling.

OpTK™ Piston Cylinder Actuators

Dynamic positioning accuracy means precise control.

Optimux’s spring cylinder actuator is a key element to the OpGL™ excellent shutoff characteristics. The OpTK™ delivers more than three times the linear force offered by traditional diaphragm actuators while providing excellent throttling characteristics, stiffness and accurate response to control signal. The OpTK™ has been designed for supply pressures up to 150 psi (10.3 Bar), and unlike diaphragm actuators is field-reversible for air-to-open or air-to-close operations without any additional parts. The OpTK™ dynamic positioning accuracy means precise control, and faster response time upon the command of the control signal. The supply pressure is directed to both sides of the piston by the positioner, for stiff and precise actuator operation. This is a significant advantage over diaphragm actuators which depend only on spring robustness and a diaphragm membrane (both susceptible to degradation and wear).

OpRPA ™Rack & Pinion Actuators

Designed for extremely long cycle life.

Optimux’s Series RPA represent an excellent alternative to our RA Piston-Cylinder Series for rotary valves applications. As with the RA Series the RPA actuators are compact, allow for field reversibility, provide adequate torque for most standard applications and are easy to maintain. RPA actuators are designed for extremely long cycle life when utilized in normal loading applications. The Series RPA actuators are also offered for all our rotary valves: Series DX and Series VB.
