316 S.S 3 way, L port ball valve, with spring return actuator.G1/4", 8mm bore, RTFE seat, FKM seals, live loaded packingVacuum-68 BAR pressure range, media temp -20°C to 180°C.Anodised & coated aluminium spring return pneumatic actuator SR50

High performance 3 way (L and T port) reduced bore 316 Stainless Steel ball valve with BSP threaded connections and a spring return pneumatic actuator. Self adjusting stem packing assembly with Belleville spring for temperature fluctuations and vibration. Long neck to minimise any thermal transfer from valve to actuator. Reinforced PTFE seats for temperatures up to 180°C. The spring in the actuator allows the valve to return to a rest position in the case of loss of air. Typical applications include water treatment, chemical, marine, petrochemical and general industry.
