We supply many brands of Pneumatic actuators at the best prices and these can be fail-safe or simply open/close. We can also combine an electro-pneumatic positioner to create a propional control valve, especially for Ball and Butterfly valves. This can also be made Fail-Safe, whether Fail Closed or fail Open, if air or control signal is lost. We are expert in all things related to Valve control and we offer advice on your needs free of charge. Always allow us to Quote no matter how many others you get.
