Leslie L Series Internal Pilot, Piston-Operated Reducing Valves and LX Series Differential Pressure Regulators

• 1/2 - 3" Valve Sizes • End Conn.: THD, SWE, BWE, RF
• ANSI CL 125 - 600
• Body Mat'l: Cast Iron (LKY), WCB (LS-5), Bronze (LY)

General Pressure Reduction and Regulation Service

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.

L Series valves are available with Teflonฎ self-cleaning piston seal or metal piston rings.

Differential Pressure Service

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.

LX Series regulators are adjustable to a differential pressure range of 5 psi to 40 psi. All valves in this series provide this differential range, without changing springs or diaphragms.

These differential pressure regulators are available in the same sizes and ratings at the "L" Series reducing valves.

Leslie LC Series, for Gas, Liquid or Steam Service

• 1/2 - 3" Valve Sizes  • End Conn.: THD, SWE, BWE, RF
• ANSI CL 300 (Bronze), CL 600 (Steel)
• Body Mat'l: WCB (LCBS), Bronze (LCB)

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.

These small valves can be ordered with bronze or steel bodies, only in 1/2 inch size. They can handle inlet pressures as high as 1000 psig and are available with pressure reduction ranges of 2-35 and 25-400 psig.

Leslie J Series Self-Contained Reducing Valves

• 1/2" Valve Size  • End Conn.: THD
• ANSI CL 300  • Body Mat'l: Bronze

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.

Maximum inlet temperature is 150ฐF for air and gas service, 550ฐF for steam service. Maximum pressure is 300 psig for steam and 400 psig for air or gas. Available reduction ranges are 1-50 psig and 5-290 psig.
