Air Operated 1/2" thru to 4" Threaded and 250 Cast Iron Flanged
Super G Series valves are quite simply the best pressure reducing valves on
the market. Available in versions suitable for steam, air and gas pressure and
temperature control, they combine the simplicity of a self-contained regulator
with the performance of more sophisticated control systems at a fraction of the
cost. All Super G regulators have a very high rangeability (100:1) with no
maximum pressure drop or pressure ratio limitations, and are very accurate over
their full flow range.
Simple and Reliable
Leslie Super G
There are only two moving parts in the valve body, making for drastically
reduced maintenance headaches. The main control component is our exclusive
Spiroflex® stainless steel diaphragm that operates smoothly over the full flow
range and is capable of longer travel for high flow capacities. This is a
long-lasting diaphragm with minimal maintenance characteristics. Another benefit of the
Spiroflex® diaphragm is the ability to achieve total control with a minimum
delta-p of 0.5 psi.
Many replacement parts are common across the line, thus reducing parts inventory
cost. And those parts that might need inspection and replacement can be serviced
without removing the valve from the line.
An Unusual Three-Year Warranty
Leslie Class GPK, GPB, and GPKP-1 pressure reducing valves, when installed and
operated in accordance with our instructions, will be repaired or replaced free
of charge if a failure should occur within three years from our shipping date.
(We cannot be responsible for special or consequential costs or damages.)
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.

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 Teflon® 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.
