Flowserve Limitorque MXa SIL 3 valve actuator

The Limitorque MXa valve actuator has a SIL 3 rating and is designed to provide reliable actuation in critical environments without compromising safety instrumented systems.

Acrodyne Acro-Matic pneumatic actuators and accessories

Acro-Matic pneumatic actuators and accessories cover a range of torque outputs from 5 to 5000 Nm with a rack and pinion drive mechanism. The actuator is claimed to provide long and reliable service as the power pack.

Beck drives electric actuators

Beck drives are designed electric actuators that offer consistent, precise control without the performance and maintenance limitations of typical actuators. Unlike pneumatic and conventional electric actuators, the drives can withstand continuous duty modulation without degradation of performance. The electric actuators combine the positioning necessary for optimum control with the reliability to keep the process running.

Schischek ExMax-...-F1 quarter-turn spring return rotary actuators

The Schischek ExMax-…-F1 quarter-turn spring return rotary actuators are claimed to be able to close rotary valves and dampers in less than one second. Fields of application include ball valves, butterfly valves, venting dampers and air and fire protection dampers.

YTC YT-2501 smart valve positioner with remote sensor

The YT-2501 smart valve positioner from YTC has a remote sensor that is fitted to the actuator with the valve positioner located away from excessive heat or vibration. Communication between the sensor and positioner is via a communications cable that can be ordered to suit various distances.

Limitorque QX quarter-turn, smart electronic valve actuator

The Limitorque QX quarter-turn, smart electronic valve actuator includes an absolute encoder for tracking position without the use of batteries. The QX design provides enhanced safety and reduced downtime through improved diagnostics, built-in self-test (BIST) features and LimiGard fault protection.

Harmonic Drive gears

The Harmonic Drive operating principle allows high reduction ratios with concentric shafts and with no backlash and vibration. It is based on a simple construction comprising three components: Wave Generator, Flexispline, and Circular Spline.

Smart positioner

The YT-2350 smart electro pneumatic positioner is housed in a Stainless Steel 316 IP66 enclosure and fits well in areas of high corrosion. It is available in both rotary and linear design. Incorporated in the design is an easy-to-see LCD offering logical auto calibration and parameter setup. The option of HART communication and 4-20 mA feedback signal are available in both the linear and rotary designs.

Non-intrusive actuator

The Accutronix MX is Limitorque's entry in the non-intrusive, double-sealed, smart electronic actuator marketplace. The product has been readily accepted into all major market segments, including power generation, petrochemical and water/wastewater treatment.
