UV Stabalised PVC Spring Return Ball Valve
2 way UV stabilised PVC ball valve with spring return pneumatic actuator (fail close or fail open). Comes with PTFE (Teflon) seats and our unique double stem seal system (standard in EPDM but also available in Viton). Great for corrosive or chemical media where traditional material such as brass and stainless steel are not suitable. Anodised aluminium actuator with visual indicator will close or open when air is lost (depending upon your choice). Commonly used in the aquaculture industry (sea water), chemical dosing, water treatment and pool filtration. Available with BSP threaded (Threads conform to ISO 7.1 Sealing Threads) and solvent weld ends (ANSI Standard designed to fit Schdule 40 & 80 pipe).
