High performance 3 piece full bore 316 Stainless Steel ball valve with BSP threaded connections. 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. This ball valve has a lockable lever operation so it can be locked in one position if needed. Typical applications include water treatment, chemical, marine, petrochemical and general industry. Length to DIN3202-M3, Threads to ISO7/1 and mounting pad to ISO5211. Watermark valves available upon request, contact Sales for more information. Watermark License Number WMK26529 approved to WMTS 012:2018.
