Pneumatic Diaphragm Control Valve
8 products found
A pneumatic diaphragm control valve is a rapid-response, modulating process control valve powered by compressed instrument air acting against a heavy-duty flexible elastomer diaphragm to deliver precise fluid regulation. The pneumatic actuator works in tandem with a precision digital positioner (receiving a standard 4-20mA signal) to adjust air pressure within the diaphragm chamber, perfectly balancing a multi-spring return system to move the valve stem and plug to the exact calculated position within the contoured valve seat. Process automation engineers and industrial plant contractors can ensure dynamic flow stability and rapid fail-safe operation by importing certified pneumatic diaphragm control valves directly from leading manufacturers in China via our advanced B2B digital marketplace.
