CVSeriesProcess ControlValves
The CVE’s innovative design makes it among themost versatile process control valves in the world.
Its cage-guided Kwik-Change Trim® utilizes multi-interchangeable trim styles, eliminating the need tochange body style.
The CVE Series Process Control Valves are availablewith balanced or un-balanced trim for oil, gas, chemical,power and refining applications. Body styles includeboth globe and angle configurations with a choice offlanged, buttweld, or threaded connections.

CVES CVETCVEDCVEZ
The CVES trim design isun-balanced and cage guidedwith cage profiled flow charac-teristics. With optional shutoffclasses IV, V and VI, this designis used over a wide range of tem-peratures and pressures in a mul-titude of clean services.
The CVEZ trim design isun-balanced with rugged “post-guiding” and plug profiled flowcharacteristics. Offering shutoffclasses IV, V and VI, this designis especially suited for erosive,viscous or particle contaminatedfluids and in “low flow” applica-tions.
The CVED trim design isbalanced* and cage guided withcage profiled flow characteris-tics. Standard class II shutoff,with class III and IV optional.The CVED is designed for useover a wide range of pressuresand temperatures in clean fluids,gases and/or vapors.
*Balanced trims substantially
reduce actuator thrust
requirements.
The CVET trim design is amodified version of the CVED
model. Standard class IV and Vshutoff is achieved with anupgraded plug seal ring and a“soft seat” insert. Metal seating isoptional. Maximum tempera-ture limit is 450°F.

CRYOGENIC CONTROL VALVES
T3 Energy Services manufac-tures a range of specialized auto-matic and manual control valvesfor cryogenic service. The experi-ence of the engineering staff inthe field of cryogenic design hasled to the development of variousconstructions to suit the majorityof applications.
The basic cryogenic bonnetdesign may be modified forinstallation into fabricated ‘coldbox’ units.
Two main features of the T3Energy Services extended bonnetsfor cryogenic applications includethe capability of removing thevalve ‘topworks’ from outside a
‘cold-box’ to withdraw the plugand stem assembly for inspectionand the inclusion of PTFE spoolswith carefully machined labyrinthgrooves and vapor pockets toreduce heat transfer by conduc-tion.

MANUAL OPERATED ACTUATOR
The Series CVH Manual Operated Actuator is used when onlydirect manual operation is required. Control valves are positionedprecisely and an indicator is provided to show valve position and travel.
The handwheel operates through a revolving nut mechanism, whichengages with a lead screw. An anti-twist device is incorporated intothe basic design to provide linear motion.
Low friction thrust bearings ensure ease of operation throughoutthe valve travel. The actuator stem is positively coupled directly tothe valve stem by a split connector.
FEATURES:
• High power.• Positive stem connector, split for ease of attachment.• Spring-loaded detent action ball built into handwheel • prevents movement due to vibration.• Rigid iron and steel construction.• Stainless Steel travel indicator and scale.

Series CVD Series CVR
The CVD and CVR Pneumatic Actuatorsmake available a choice from a wide rangeof units to satisfy the majority of controlvalve applications.
The Series CVD is a direct-acting(increasing air extends the stem), the SeriesCVR is reverse acting (increasing air retractsthe stem).
Both actuator assemblies are of rigid construction, and may be used on a widevariety of globe and angle style controlvalve assemblies to ensure peak perform-ance for both modulating and on/off appli-cations.
The spring-opposed diaphragm actuatoris designed to provide linear operation andposition the valve plug in response to vari-able changes in instrument output signals.
As controlled air enters the diaphragmchamber, the pressure generates a forcewhich overpowers the spring force andmoves the stem assembly in a linear direc-tion. As the air supply decreases, the com-pressed spring force overpowers thediaphragm force, and moves the stem in theopposite linear direction.
Actuator sizing procedures, and a fulllisting of actuator performance data aredetailed in the CV Series process controlvalve bulletin: CVACT
