The Series CPT Characterized Seat Control Valve is a high technology, final control element that matches the performance of computers & PLC's

After years of research and evaluating performance in actual harsh throttling conditions and in applications requiring precise computer control, Worcester has developed a new control valve technology. The Series CPT advanced throttling control valve exceeds the best performance features of traditional linear valves, segmented ball and eccentric plug designs. The Characterized Seat Control Valve is a ball valve, but there the similarity ends. The throttling part of the valve is based on a patented seat technology consisting of a standard sintered stainless steel seat, impregnated throughout with TFE or graphite, that is laser cut to provide state of the art modulating control. Combined with our high cycle pneumatic or electric actuators, positioners and accessories, you have a throttling control valve package that can match the performance possibilities of computers and PLC controllers.

The characterized seat design allows use of exotic materials such as Inconel 600, Hastelloy C22 or Monel. FM Oil & Gas Safety Shutoff. The 8mm -50mm CPT 44 series valves and 15mm'- 100mm CPT 51/52 valves with PULSAIR, are approved by Factory Mutual for Oil & Gas safety shutoff service and flow control. Standard P Capabilities Liquids to 500 psi Steam to 300 psi.

These valves provide a very cost effective alternative to the more expensive valves manufactured in exotic materials such as Hastalloy, Titanium etc. One piece ball and stem ensures there is minimal play between valve and actuator, giving precise and responsive control. One piece PTFE bellows type packing is pre loaded using a Stainless Steel spring gland follower and ensures no leakage to atmosphere even during hot and cold cycling. Valves are designed with optimum lining thickness to ensure permeating media such as Chlorine does not come into contact with the body. All products are finished externally with a high quality epoxy paint.

Features and Benefits:

  • Cv range of .8 - 400
  • Equal percentage characteristic
  • Blow out proof stem
  • Double stuffing box for applications requiring absolute safety
  • Tight Shut Off
  • Liners are anchored and suitable for use on vacuum applications
