Hattersley Fig 861 PN16 Wafer Check Valve

**Valpres Figure 72 Series Wafer Pattern Full Bore Ball Valve** Introducing the Valpres Figure 72 series wafer pattern full bore ball valve, designed for exceptional performance and reliability. This valve features a robust stainless steel ball and stem, complemented by P.T.F.E. seats and P.T.F.E. / FKM (Viton) seals. Engineered to flanged (wafer pattern) standards, it is compatible with PN16 flanges and operates via a user-friendly lever mechanism. Paired with a Valbia 82 series pneumatic actuator, this valve is ideally sized for a minimum pilot air supply pressure of 5.5 Bar g. Its innovative rack and pinion design, crafted from hard anodised aluminium, ensures durability. The blue-coated end caps offer additional protection, while the visual position indicator makes operation straightforward. Pneumatic connections are facilitated through 1/8” BSP fittings, and the actuator includes bi-directional open/close travel stops. It operates effectively under a maximum air supply pressure of 8 Bar g and bears an ATEX II 2GD T6 certification for safety. A mounting kit is also included, with the entire assembly rigorously tested for functionality. **Specifications** - **Size Range:** ½” to 6” - **End Connections:** Available in PN16, PN40, PN63, ANSI 150, ANSI 300, and ANSI 600 standards. - **Body Materials:** Choose from carbon steel or stainless steel for tailored durability. - **Valve Options:** An ISO direct mount version is available, suitable for sizes 1” to 4”.
