Plug Throttling Valves
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.
Bonnet options include the standard bolted configuration; an extension
bonnet for extreme temperatures; a lube/ vented bonnet for purge, leak-off
or lubricator connections; bellows bonnets for zero exterior leakage; and
oversized bonnets when required.
A variety of packing and gasket options are offered to meet the
requirements of a range of process conditions. Packing options include PTFE
V-Ring, PTFE shredded, high temperature carbon graphite, PTFE aramid,
graphite aramid and high temperature Inconel® glass. Choices for gaskets
include PTFE, high temperature carbon graphite and nitrile rubber bonded
non-asbestos.
Cage Throttling Valves

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.

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.
Superior features include smoother throttling, greater accuracy,
non-fouling, non-sticking, compact size and reversible action.
