Leslie Controls Steam Valves

Leslie Pressure Reducing Valves

Leslie GPK and GPKP Series Regulators 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 come in a self-contained regulator or a piloted.  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.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
