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).

Hung-Cage Construction

A unique hung-cage throttling  design eliminates gasket damage and bonnet or seat leaks  due to thermal expansion. Anti-cavitation (Les-Cav)  and low-noise (Les-Sonic) cages are available for  special situations. Cages and trim material are 400  series stainless steel with optional Stellite®  hardfacing available.

Standard valve packing is braided Teflon® graphite.  Teflon® chevron and graphite type II is optional for higher temperature service.

Easy Maintenance

The cage trim is easy to remove for inspection or  replacement. There are no welded, screwed-in or press-fit parts. Capacity changes are achieved simply by replacing  the cage. There's no need to replace any other parts or add any adapters.
