MEB Hex Extension Fitting

The inlet and outlet ports on the PRD series regulators are designed for use with fittings that have a hex size of 5/16" or less. To avoid interference with a larger fitting we recommend the use of an MEB-1010 series extension adapter.

Description: The PRDB series regulator features an improved valve design compared to the PRD series regulators. This allows for improved seal reliability and precision at very low outlet pressures, pressure differentials, and flows.

Max Inlet Pressure Rating: This is a single stage regulator, and is ideal for applications with steady inlet pressures up to a maximum of 500 psig.

Outlet Pressure Range: Maximum outlet range 0-50 psig. The large valve to sensing area ratio and frictionless design of Beswick’s diaphragm style regulators make them especially well suited for low pressure regulation, such as ½ psi.

Approximate Weight: 25g in brass and stainless steel (303 & 316). Weight will vary slightly, depending on configuration.  Selecting the 2 inch. high resolution cap option adds approximately 50-60g to total weight.

Porting: 10-32 internal threaded inlet and outlet ports.
This is a Non-Relieving regulator.
