PTFE seats combined with elastomer O-rings ensure tight shut-off, low friction, and broad chemical compatibility. The full bore design allows maximum flow capacity with minimal pressure drop.\u003c\/p\u003e\n\u003cp\u003eThe pneumatic actuator uses a rack \u0026amp; pinion mechanism with a 90° quarter-turn rotation at 4–6 bar air supply. Two configurations are available: \u003cstrong\u003eDouble Acting (DA)\u003c\/strong\u003e — compressed air controls both open and close operations; \u003cstrong\u003eSpring Return (SR)\u003c\/strong\u003e — air opens the valve while a spring returns it to a fail-safe position on air loss.\u003c\/p\u003e\n\u003cp\u003eISO 5211 mounting and NAMUR interface allow easy integration with solenoid valves, limit switch boxes, and positioners for PLC\/SCADA automation systems.
