Application:
Pneumatic diaphragm single and double seated control valve
are one of the final controlling elements most widely used in
automatic controlling system. Their function is: receive the output
signal pressure from pneumatic controller (or electric controller,
electric signal transferred to air signal) to change the flow of
controlled fluid by changing the valve opening, thus flow, pressure,
temperature and level of fluid can be controlled, the process of
production can go forward normally according to the preset
requirement and will realize automation. Pneumatic diaphragm
single and double seated control valves have the advantages such
as simple construction, reliable action, easy maintenance and
explosion proof, etc. They can be widely used in chemical industry, petroleum,
metallurgy industry and power station for automation.
