Description
High performance 3 piece full 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. Pre-drilled metric hole on ISO5211 direct mounting pad to minimise any thermal transfer from valve to actuator. Reinforced PTFE seats for temperatures up to 180°C. Anodised aluminium spring return pneumatic actuator which allows a fail safe position if air is lost. Typical applications include water treatment, chemical, marine, petrochemical and general industry. Length to DIN3202-M3 and Threads to ISO7/1.
