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.
Size Range: 25-150mm
Operating Range: -60°C - 200°C (Depending on
design & Materials)
Body Material: S G Iron, Stainless Steel
Seat Materials: PTFE
Ball Material: Stainless Steel with PFA or FEP coating
Lining Material: PFA, FEP, PVDF
End Connections: Flanged BS4504 Table 10/16, ANSI 150/300LB
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.
