1 Worcester Controls C44 Cryogenic 3-Piece ball Valves2 High Flow RateThe high Cv available from a ball valve compared with aglobe valve makes the C44 ideal for loading stations wherespeed of delivery is critical. The valve is also available asfullbore up to DN40 as the C59 Body MassThe one-piece design minimises the mass of the body andtherefore makes the valve economic to use. It also provides aweight advantage, making the valve ideal for road tankers andother transportation of OperationThe unique low torque seat design and the 90 degreeoperation of the ball valve makes it ideal for use with bothpneumatic and electric actuators with the additional benefit ofrotary control if required. When manually operated, the leverprovides visual indication of the valve orientation (open orclosed) which is critical in the safe loading and unloading ofliquid of MaintenanceThe 3-Piece concept provides the benefit of easy maintenancethrough the "slide out" body Worcester's experience and expertise in thedesign of Cryogenic ball Valves has been recognisedthroughout the process industry for over 30 years.
2 Utilisinga combination of our Fluorofill seat material and our unique'S' gasket body seal, the valve provides positive shut-off inthe most demanding of Cryogenic applications. From theoriginal C44 R5 and MC44 designs the seat and body sealshave remained a constant feature and with both productsnow rationalised into the C44 R7, additional technicaladvantages have been included to provide what isconsidered the best Cryogenic ball valve on the Worcester 3-Piece ball valve offers a number of technicaladvantages over other types of and certified to EN1626 and can be used on TPEDCATIII Valve DesignOverview .. 2-3 Parts/Materials ..4 Valve Dimensions ..5 Throttling Control of Cryogenics .. 6 Other Cryogenic Products ..7 Contents3 Automation- Solid actuator mounting platform foron/off and control applicationsExtension- minimal gap to reduce frost line andminimise heat transferBody- one piece design provides optimum strengthand low body mass'S' Gasket- 316 coated PTFE to compensate forthermal fluctuationsSeat- Low torque design manufactured in FluorofillPTFEStem- one piece anti-blowout design with ball reliefhole position indicationBall- With cavity pressure relief hole and fool-proofstem alignment devicePacking- Chevron design for optimum sealing lifeconsisting of a PTFE chervon seal captured between2 graphite chevron Thrust Bearing (Halves) Ring (Halves)

4 (mm)(kg) Worcester V-Flow provides positive shut-off with accurate control by utilising a Cryogenic flourofill seat downstream and a metal profiled seat upstream. The choice of seat profile on the upstream seat is dependent on the flow conditions required. The V-Flow is ideally suited for either electric actuation using a 75 series Norbro DataFlo P or pneumatic 40R series with a PMV combination of the V-Flow with the Cryogenic C44 design provides an ideal Cryogenic control valve for a variety of applications from food freezing to high purity Control of CryogenicsThe relationship between ball position and characterised seat allows for precision throttling V~Flow control Valves are sized to ideally control between 20 - 80% opening of the Seat Selection (some typical examples)Flow Characteristic OptionsSlotted Seat(linear characteristic)Custom Seats(special applications)30 Seat(equal percentage)60 Seat(equal percentage)
