Cashco (FRA Certified) Main Body Air Regulators


Cashco main body regulator.

Used for extremely precise air regulation.

Model: DA4-DN25.
Inlet/Outlet: 1" NPT.

Model DA4 is a pressure reducing regulator used to control downstream (outlet or P2) pressure. With proper trim utilization, the unit is suitable for liquid, gaseous, or steam service.

Model DA4 is high performance, pressure loaded diaphragm-type, flow-to-open pressure reducing regulator. Design includes an internal pressure balancing piston cylinder that provides high flow capacity and high pressure drop capability. The internal trim design allows the same basic unit to cover a broad range of pressure settings. Performance meets or exceeds that of competitive pressure loaded or pilot-operated designs. The DA4 regulator is applied primarily in clean gaseous service, but may also be applied as a liquid or steam valve. Truly a “DO-ALL” pressure regulator.

Refer to Technical Bulletin DA4-TB
for design conditions and selection recommendations. (NOTE: This product was formerly identified as a Model
D4; a Model DA4 and D4 are one and the same product.)
