CONTROL VALVES INSTRUMENTATION …

1 Product Digest 1 6 CONTROL VALVESINSTRUMENTATIONREGULATORSSTEAM water HEATERSSERVICE FABRICATION2It has been one hundred years sinceCanadian born John Leslie advertisedhis first major product, a steam poweredsnowplow for railroad locomotives. By1905 The Leslie Company was operatinga foundry, machine shop and small officein Lyndhurst, New Jersey, and building areputation for producing reliable steampressure VALVES and regulators. Thecompany was a major supplier of steamcontrol equipment for military andmerchant ships during both World Warsand has continued as a supplier of mili-tary/commercial marine service s product line grew over the yearsto incorporate equipment for industrialand utility customers, and in 1968 thecompany moved into a larger plant inParsippany, New Parsippany, Leslie built on decadesof experience manufacturing highquality VALVES for military and industrialmarkets to solidify it s reputation as apremium quality manufacturer.

2 Withproducts such as the venerable Super G Series regulators and theClass DLO CONTROL valve moving our headquarters to anewly built 150,000 sq. ft. facility inTampa, Florida, Leslie broadened it sscope to encompass a comprehensivearray of products for total fluid manage-ment of steam and other fluids. In 1990,Leslie Controls was purchased by one ofthe world s largest independent valvemanufacturers, Watts Aeroflow product line, one of themost innovative and diverse family ofcontrol VALVES in the world, was intro-duced in 1994. Our 1995 acquisition ofthe K&M Valve Company added thewidely recognized K-Max Rotary, GTBTop & Bottom Guided, GTW 3-Way andSynflow Sweep Angle CONTROL valve linesto our Process Chemical and Oil & GasIndustry offerings.

3 In 1999, Watts Indus-tries split and Leslie Controls became acorporation in the Fluid RegulationDivision of the newly formed NYSE company, Circor International. A fewmonths later, the CPC-Cryolab line ofcryogenic VALVES was added to the Leslieproduct 250 employees, Leslie Controlshas grown to serve power generation, oiland gas, petrochemical, chemical process,HVAC, food processing, commercialmarine, and military marine marketsthrough a network of over 100 manufac-turers representatives Century of Superiority in the Handling and CONTROL of FluidsQuick Delivery Program ..3 Linear CONTROL VALVES ..4-7 Rotary CONTROL VALVES .

Aeroflow s shut-offcapability is in a class all its own. Thepilot balanced plug design minimizesactuator size and cost. Proven pilotdesign also eliminates the need for anypiston seals to insure tight shut-off,greatly increasing the valve s InterchangeablityWith the exception of bodies, all partsare interchangeable between globe andangle body styles with the same sizeand function.

7 Facilities needingvarious trim designs in both globe andangle style bodies can minimize partsinventories, maintenance and Protected Seat DesignProven in more than 20 years of powerplant service, Leslie s protected seatdesign protects Aeroflow s superiorshut-off characteristic three , the protected seat prevents highvelocity transients at opening orclosure of the valve. Secondly, a five-stage pressure drop occurs near theseating position and last, the plug/seatsurface is withdrawn from the directflow to prevent direct particle impinge-ment or clamping. The Tri-Sheerallows prolonged throttling at the seatwithout wire draw due to highclearance flow Seat DesignIn 4-16 body sizes, Aeroflow's seatring is not threaded, welded, or loadedin place by the cage.

8 Seat retention andseat gasket loading are accomplishedwith a stainless steel load ring andmultiple silver-plated load screws forcontrolled seat gasket loading which isimpervious to thermal Cage for Thermal ExpansionThe quick-change seat features a cagewhich is hung in the body. This allowsthe cage to expand freely throughsudden wide variations in fluid tempera-ture. This tolerance for cage expansionsolves the typical problems seen incage retained designs such as cagewarping, plug binding, galling, andcrushed unique technology of the Aeroflow begins with aerodynamic vanes cast intothe valve body inlet and outlet. Inlet vanes help divert incoming flow evenlyaround the cage, minimizing turbulence and flow instability as well as improvingflow capacity.

9 Outlet vanes minimize turbulence to reduce noise and bodyerosion. A wide range of interchangeable trim options and custom characterizedcages provide the flexibility of many sought after Conditioning EquipmentLeslie offers it s unique Aeroflow pressurereducing valve in combination with a stateof the art, variable area, mechanicallyatomized desuperheating system. Thiscombination system meets today sstringent requirements for CONTROL andturndown without the temperature stressproblems associated with combinationvalves. We offer complete fabricatedsystems that include either Globe or Anglebody PRV designs with noise attenuationplates (as required), customized trimselection and desuperheating Characterized Cage ThrottlingMassive 400 Series stainless steel cagesresist warping or deformation andprovides plug/window throttlingthrough closure.

Thiscustom characterized cage is standardin our Aeroflow CONTROL valve line andis available with all plug/seat Multi-Stage CageLes-Cav multi-stage trim is designedto throttle liquids with maximumpressure drops from 0-4000psi withoutdamaging cavitation and resultantnoise or vibration.
