Charakterystyka

Keystone CompoSeal Resilient Seated Butterfly Valve

Innovative wafer style body and disc in high engineered composite results in excellent internal and external chemical resistance.
Light weight construction results in lower cost and simplified installation.
No extra pipe support needed when installed in plastic or GRP piping.
Disc in high engineered composite material provides excellent corrosion resistance.
All fasteners in stainless steel 316 as standard.
Bubble tight shut-off in both directions, in accordance with EN 12266-1 leakrate A.
Pressure range up to PN 16 at elevated temperature.
Valve can be used in high line velocity applications up to 12 m/sec.
Spindle and primary valve seals are not influenced by the flange bolting force or pipe flange type.
High Kv (Cv) value.
No need for flange gaskets.
Primary stem sealing exceeds the pressure rating of the valve and prevents leakage through the shaft area to atmosphere.

Emerson Powered Actuator

Direct mounting to all Keystone butterfly valves and ball valves.
Valve connection compatible with Keystone (imperial and metric) and ISO 5211.
Double Rack and Pinion design nullifies side loads on the pinion shaft, minimizing bearing wear and extending life.
