Keystone-K-CompoSeal Valve Powered Actuator

Keystone CompoSeal Resilient Seated Butterfly Valve with Powered Actuator

Product Description

The Keystone CompoSeal resilient seated butterfly valve is a lightweight, highly engineered composite material valve complete with powered actuator, configurable by power source, size, function and more.

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.
  • Optimized product flow with standard mounted travel stops for valve position adjustment in open and close position (+/- 5° at each end).
  • Anodized aluminium body with electrostatic powder coating (ESPC) finish provides durable protection against corrosive environments.
  • Double acting and spring return versions available for cost effective and safe operation.
  • Up to 12 individual springs offer flexible torque range for both ball as butterfly valves.
  • Pre-compressed spring design and anti-blowout drive pinion means safe maintenance and operation.
