  1. Leslie Controls Class GPK, GPB, and GPKP-1

    Leslie Controls Class GPK, GPB, and GPKP-1

    Leslie Super G Series valves are quite simply the best pressure reducing valves on the market. Available in versions suitable for steam, air and gas pressure and temperature control, they combine the simplicity of a self-contained regulator with the performance of more sophisticated control systems at a fraction of the cost. All Super G regulators have a very high rangeability (100:1 ) with no maximum pressure drop or pressure ratio limitations, and are very accurate over their full flow range Simple and Reliable.
  2. Leslie Controls J Series 1/2" Threaded, Bronze ANSI Class 300 Self-Contained Reducing Valves

    Leslie Controls J Series 1/2" Threaded, Bronze ANSI Class 300 Self-Contained Reducing Valves

    Leslie J Series small-flow reducing valves are inlet pressure-closing for positive dead-end shutoff. They are highly accurate regulators. Metal-to metal seating is available for steam service. Long-wearing resilient seat inserts should be requested for air and gas service.
  3. Leslie Controls L Series Internal Pilot, Piston-Operated 1/2" - 3" ANSI Class 125-600 Reducing Valves and LX Series Differential Pressure Regulators

    Leslie Controls L Series Internal Pilot, Piston-Operated 1/2" - 3" ANSI Class 125-600 Reducing Valves and LX Series Differential Pressure Regulators

    Leslie L Series internal pilot, piston operated reducing valves provide a high degree of accuracy over the entire flow range and a widely adjustable reduced pressure range. Single-seated, with a fully-guided main stem that closes with inlet pressure, this valve demonstrates superior ability for tight shut-off. Leslie LX Series differential pressure regulators maintain a constant differential between the air, gas or steam pressure passing through the regulator, and any other liquid or gas pressure whose relationship to the regulator outlet pressure should be a constant. The differential is maintained regardless of operating variation.
  4. Leslie Controls LC Series Direct-Operated, Spring-Loaded Reducing 1/2" - 3" ANSI Class 300 (Bronze), 600 (Steel) Valves for Gas, Liquid or Steam Service

    Leslie Controls LC Series Direct-Operated, Spring-Loaded Reducing 1/2" - 3" ANSI Class 300 (Bronze), 600 (Steel) Valves for Gas, Liquid or Steam Service

    Leslie LC Series direct-operated, spring loaded valves are ideally suited to many small volume applications where the controlled flow is air, gas, steam or liquid. Typical services include gland sealing, pilot plant operations, plastic mold presses and atomizers.
  5. Leslie Controls Model GPAK 1/2" - 4" Regulators for "Hard-to-Hold" Air, Gas & Vapor

    Leslie Controls Model GPAK 1/2" - 4" Regulators for "Hard-to-Hold" Air, Gas & Vapor

    Leslie Series GPAK regulators are ideal for air, butane, CO, helium, methane, nitrogen, natural and other gases. The principle of operation is the same as the GP Series, enhanced by several special service features. The packless construction and resilient trim give bubble-tight shutoff on gases. This minimizes costly waste of industrial gases due to valve seat or packing leakage.
  6. Leslie Controls Model GPK, GPB, GPS & GPSS Air-Loaded 1/2" - 4" ANSI Class 125-300 Pressure Reducing Valves

    Leslie Controls Model GPK, GPB, GPS & GPSS Air-Loaded 1/2" - 4" ANSI Class 125-300 Pressure Reducing Valves

    Leslie GP Series valves are air-loaded versions of the Super G Series valves. They provide all the advantages inherent in the Super G Series and allow set point changes in seconds with the adjustment of a simple air loader. These valves can be set remotely from an air loading panel. Combined with the Leslie PMC-1 controller, the GP series valve provides a temperature control loop with built-in cascading action for faster, more stable response to load changes. The packless, self-contained design provides low hysteresis and inherently "leakless" performance.
  7. Leslie Controls Model GPKP-1 Steam-Piloted, Self-Contained 1/2" - 4" ANSI Class 125-250 Pressure Reducing Valves

    Leslie Controls Model GPKP-1 Steam-Piloted, Self-Contained 1/2" - 4" ANSI Class 125-250 Pressure Reducing Valves

    Leslie GPKP-1 valves feature a unique patented dual diaphragm sensing chamber that provides unparalleled control, accuracy and stability in one self-contained package. Large pilot clearances are far less subject to fouling problems, non-continuous bleed results in less direct carryover through the pilot assembly, and the constant-gain pilot makes for unmatched performance accuracy throughout the entire operating range. A single Leslie GPKP-1 can be used in many applications where competitive designs must use multiple regulators in double reduction and 1/3-2/3 installations.
  8. Leslie Controls Model GPS-1EP External Steam-Piloted 1/2" - 4" ANSI Class 150-300 Pressure Reducing Valve

    Leslie Controls Model GPS-1EP External Steam-Piloted 1/2" - 4" ANSI Class 150-300 Pressure Reducing Valve

    The Leslie GPS-1EP features the GPS-1 regulator along with a VPS external pilot. The pilots have inter-changeable springs for 3-20, 5-50, 10-100 and 20-150 Psig pressure ranges.
  9. Leslie Controls Model VKP Pilot-Operated 1/2" - 4" ANSI Class 125-250 Steam Pressure Reducing Valves

    Leslie Controls Model VKP Pilot-Operated 1/2" - 4" ANSI Class 125-250 Steam Pressure Reducing Valves

    Leslie Class VKP steam pressure reducing valves use an adjustable, spring-controlled integral pilot valve to establish a pressure feedback loop which controls the main valve. This entirely mechanical principle tends to keep systems in equilibrium within 90 percent of the set point.
