• Minimize Sudden Downstream Load Change • Wide Pressure Ranges • P302 has internal relief valve for overpressure protection The P300 series pressure regulator is a manual, direct acting, self-operating, spring loaded, adjustable regulator. The P300 series is used in applications where pressure reduction is required. The regulator will reduce the risk of "shock" from abrupt changes of downstream conditions. This can help prevent safety equipment from shutting an operation down. Applications • Compressors • Gas Engines • Service Regulators Materials of Construction P300 Series Maximum Inlet Pressure P300 Series Range Springs

Interchangeability between the BelGAS P200 series and the P300 series The unique feature about the BelGAS P300 regulator is that it utilizes the BelGAS P200 series 1.5”x 2” and the 2” x 2” body using a simple adaptor ring. The simplicity of down-sizing a system when a BelGAS P200 unit is installed is as easy as removing the 2 body-to-head bolts and installing a BelGAS P300 head with the appropriate adaptor and bolts. Or, if a 1.5” x 2” or 2” x 2” BelGAS P300 is installed, the BelGAS P300 head can be removed and a BelGAS P200 head installed to up-size your system. It is important to know, a P300...
