The Style ‘H’ pressure reducing valve is available in two variations: Type I and Type II. Type I valves feature a pressure-tight body, spring chamber and bottom cap that forms a pressure-tight envelope capable of withstanding the full-proof pressure rating. In Type II valves, the spring chamber does not form part of the pressure-containing envelope. If no valve type is specified on an order, or if the purchaser has no preference, Type II will be provided.

The TRAC Style ‘H’ pressure reducing valve is a direct replacement (regarding fit and function) for the following manufacturers’ designations (MIL-V-2042D and later specifications): Atlas Valve Company Figure 1910, Charles M Bailey (CMB Industries) Model 30, ITT Lawler Type 2707, Leslie Controls Inc. Class WWBN, Warren Controls Corp. Type 436.

The TRAC Style ‘HA’ pressure reducing valve is intended for installation in air or nitrogen systems where the inlet pressure to the valve is 150 PSIG (or below) and it is required to maintain a constant (within the accuracy limits specified) lower pressure downstream of the valve. For air or nitrogen service applications having an inlet pressure rating higher than 150 PSIG, consider the TRAC Style ‘HG’ gas pressure reducing valve.

For air or nitrogen service applications requiring a pilot-operated pressure reducing valve, consider the TRAC Style ‘RA’ pressure reducing valve.
