Automation of Pneumatic Valve Actuators
Automating the control of process or control valves using pneumatic actuators is very common and only requires the choice and installation of a few different kinds of valves to enable a fully functioning system. It does not matter whether the actuator is quarter turn, half turn or linear for the selection of these components although whether the valve is to have proportional open and close control rather than just open and close positions, will be an important factor. Other requirements such as fast slam shut or ESD (Emergency Shut Down) will dictate the automation method. Note that many different types of control can be combined within the actuator automation circuit to deal with different operating modes, mitigation of failure of the supply pressure and other components to give the valve a failsafe redundancy capability.
For help with optimising the automation circuit design or choosing the best combination of valves to achieve your design requirements, contact us today to discuss your needs.
Filter Regulators ensure the correct pressure and safe, clean compressed air is available for the valve instrumentation
Volume Boosters enable minimum reaction times for proportional actuators, combining high flow and accurate pressure control
Lock-Up Valves to detect falling supply pressures and isolate the actuator feed to prevent uncommanded valve movement
2/2 or 3/2 pneumatic pressure switches often used for automating a response to falling supply pressure
Flow regulators for pneumatic actuator speed control. ATEX & GOST certified
Quick exhaust valves reduce response times for single and double acting actuators where high speed is crucial
3/2 and 5/2 spool valves for directional and logic control, air pilot/spring return, air pilot and return, hand operated and manual reset versions. All with ATEX, GOST and 316L stainless steel
