High temperature 3 piece full bore 316 Stainless Steel ball valve with BSP threaded connections and a spring return pneumatic actuator on a stand off bracket. Self adjusting stem packing assembly with Belleville spring for temperature fluctuations and vibration. Reinforced 50/50 stainless steel and PTFE seats for higher temperatures. Anodised aluminium spring return pneumatic actuator which allows a fail safe position if air is lost which is mounted on a pad extension. Typical applications include steam and high temperature media where normal reinforced PTFE seats are not suitable. Length to DIN3202-M3 and Threads to ISO7/1.
