KPRL Low Pressure Regulator

KPRL Low Pressure Regulator

The model KPRL is a direct-acting pressure reducing regulator for use with natural gas, air, and a variety of other gases. The regulator outlet pressure is controlled by a diaphragm and an adjustable spring. As the downstream demand for flow changes, the downstream pressure changes. These pressure changes are registered by the diaphragm and will open or close the valve as needed to maintain the downstream pressure and flow requirements. There are five orifice sizes and five springs available to cover a wide range of application conditions. With the correct orifice and spring combination, the Kenco model KPRL Low Pressure Regulator will maintain a constant pressure downstream while meeting downstream flow requirements.
