Features

Keystone K-LOK Figure 360/362 and 370/372 High Performance Butterfly Valve
  • Integrally cast mounting pad provides direct mounting of many actuators.
  • Rocker-shaped gland bridge compensates for uneven adjustment of gland nuts.
  • Extended neck allows for two inches of pipeline insulation.
  • Flattened body bore at shaft journal ports positions shaft bearings near disc, providing maximum shaft support.
  • Disc taper pins are tangentially positioned half in disc and half in shaft, placing them in compression rather than shear, which eliminates potential for failure.
  • Integrally cast disc position stop perfectly locates the disc in seat, achieving maximum seat and seal life.
  • Valve seats of various materials to extend service life in different applications.
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.
