The Leslie GPS Series features multiple different GPD regulator options. Learn More

Leslie GPB Series valves are comprised of the GPB-4, GPB-2T, GPB-4T, GPB-2TS, GPB-4TS, and GPBC models. Learn More

Leslie Series GPK 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. Learn More

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. Learn More

The Leslie GPS Series features multiple different GPS regulator options along with a VPS external pilot option. The pilots have inter-changeable springs for 3-20, 5-50, 10-100 and 20-150 Psig pressure ranges. Learn More

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. Learn More

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. Learn More

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. Learn More

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. Learn More
