Sanitary Pneumatic Diaphragm Valve
The Pneumatic Diaphragm Valve is an automated sanitary valve actuated by compressed air. It integrates a hygienic stainless steel valve body with a pneumatic actuator (single-acting spring-return or double-acting) for reliable, repeatable on-off or modulating control in automated process lines. The valve can be fitted with a positioner, solenoid valve, limit switch, or position indicator to suit various automation and control system requirements.
