The Cashco Model DA4 is a high-performance, pressure-loaded diaphragm-type, flow-to-open pressure-reducing regulator. It can handle an inlet pressure of up to 3705 psi and up to 1500 psig pressure drop in multiple spring ranges. The model DA4 can be utilized in a wide variety of applications such as clean fluids, natural gas, air, oil, and corrosive and non-corrosive chemical services. With the pressure-loaded diaphragm and the balanced trim design, the DA4 can meet or exceeds that of the competitive pressure-loaded or pilot-operated designs by providing high flow capacity and high-pressure drop capability.
