Control accessories enhance actuator performance by enabling accurate positioning, system integration, and environmental adaptability. These components are essential for achieving reliable operation, tight control, and effective feedback in automated valve systems.
Electro-pneumatic positioners convert electrical control signals into proportional pneumatic output to modulate actuator movement. An integrated I/P transducer regulates air supply based on the input signal, enabling precise valve positioning. Feedback mechanisms (such as Hall-effect sensors or mechanical linkages) monitor valve response and continuously correct deviations. Advanced models support HART or Foundation Fieldbus protocols for diagnostics, remote calibration, and control loop optimization.
Solenoid valves control pneumatic flow by energizing an electromagnetic coil to shift an internal spool or poppet. These valves are used to actuate valves, with configurations ranging from compact inline designs to multi-port manifolds. High-cycle durability and reliable sealing ensure consistent pilot actuation under varying load conditions.
Switch boxes provide both visual and electrical indication of actuator position for quarter-turn valves. Designed to mount on VDI/VDE 3845-compliant actuators, these devices integrate limit switches, terminal blocks, and beacon indicators in a single enclosure. Compact models support space-constrained installations, while larger variants offer expanded terminal capacity and multi-switch configurations. Explosion-proof options are available for use in hazardous environments, enabling reliable status monitoring under demanding conditions.
Filter regulators maintain clean, stable pneumatic supply pressure for actuator control. By combining particulate or coalescing filtration with precision regulation, they protect downstream components and stabilize actuator response in systems with fluctuating air supply. Units are available in a range of port sizes, materials, and pressure settings.
These sensors enable continuous or discrete valve position feedback for both linear and rotary actuators. Linear position sensors provide analog output signals based on actuator stroke, using a contactless mechanism to track piston movement. Designed for integration with pneumatic actuators, they can be retrofit in the field for added flexibility. Inductive proximity sensors offer compact, reliable position detection for quarter-turn valves and mount directly to VDI/VDE 3845-compliant actuators. Multiple output options support compatibility with a wide range of control systems.
