These versatile single-seated, unbalanced, cage-retained trim, diaphragm control valves put the premium on performance at a competitive price. Suitable for use in steam, water, gas and process applications, this valve series has found acceptance in industries ranging from food and beverage processing to power generation. Learn More

These Leslie control valves are rugged, reliable units specially designed for use in steam, water, gas, vapor and non-corrosive liquid service. The balanced cage-throttling design permits these valves to be operated with small, compact and economical actuators against fluid pressure drops up to 1480 psig and 800°F, subject to body pressure/temperature ratings and actuator limits.

The Leslie VLG Lil' Gator general service control valve features a compact, efficient design. VLG control valves provide greater flow capacity and performance than most comparable models, yet are economically priced. Special features range from a streamlined body that minimizes turbulence and pressure drop to erosion resistant stainless steel trim. You can select from multiple port sizes and flow characteristics to meet your application requirements. Learn More

In dirty, sticky, and erosive applications, where cage guided valves fail, plug characterization, stem guiding, and balancing effect give the double-seated GTB design the best combination of features necessary to succeed. Since inlet pressure exerts force on the upper and lower plugs, the forces are balanced. This balancing effect reduces the net thrust required to move the plug, allowing for smaller actuators to be used in higher pressure drop applications and resulting in lower overall installation cost and dimensional envelope.

The unique technology of the Aeroflow begins with aerodynamic vanes cast into the valve body inlet and outlet. Inlet vanes help divert incoming flow evenly around the cage, minimizing turbulence and flow instability as well as improving flow capacity. Outlet vanes minimize turbulence to reduce noise and body erosion. A wide range of interchangeable trim options and custom characterized cages provide the flexibility of many sought after benefits.

Leslie Class GTW plug throttling, three-way globe valves are designed for mixing or diverting clean, dirty, viscous and corrosive liquids; high and low pressure steam; and clean, dirty and corrosive gases. Seat, plug and stem material is 316 stainless steel. Shutoff is dependent on installed service requirements. Class II, IV or V shutoff is available on either or both of the two inner valve ports.

The Leslie Class DOT cage throttling, 3-Way control valves provide easy maintenance and increase valve stability and trim life. Spring loaded Teflon® chevron stem packing eliminates the need for periodic adjustment. The DOT features a one-piece body eliminating the conventional tail piece and extra gasketed joint. Common applications include the circulation of water, oil, sea water, or other liquids in heating/cooling systems where there is a heat exchanger bypass control. They can also be used in blending systems and on/off selector systems. Learn More

These relatively low-cost valves are designed for bypass temperature control systems in industrial, utility and marine applications. They require very low operating forces and can be used with smaller actuators, further reducing system cost. Leslie rotary valves allow nearly twice the overall flow capacities of globe types, resulting in extremely low pressure losses and allowing the use of smaller sizes. Learn More
