Advantages
– The spherical contact between valve disc and liner ensures durable and permanently tight shut-off.
– Keyed connection between shaft and valve disc- – Dry shaft, no contact with fluid handled
– Sealing to atmosphere is ensured even when the actuator has been removed.
– Marking indicates position of valve disc
– Valve equipped with stainless steel plain bearing with reinforced PTFE coating depending on DN
– The elastomer liner provides tight sealing at the flanged line connections, eliminating the need for an extra gasket.
– Reduced pressure losses by optimised valve disc geometry
– Thrust insert for reduced friction- – Absorbs the weight of the valve disc when the valve is installed with the shaft in the vertical position
– Valve certified to
- – WRAS for drinking water applications, with XC elastomer liner
– Valve actuation options
- – Manual
– Electric
– Pneumatic
– Hydraulic -
