The Quadra-Powr™ spring-diaphragm actuator is specially designed to provide safe, reliable operation by air, water, and other mineral-based hydraulic fluids, even with minimum supply pressure. Its rolling polyamide diaphragm design provides accurate and smooth control and performs in both control and On/Off applications. It also allows field-reversible operation without disassembly – fail open or fail close modes can be switched quickly in the field by simply inverting the actuator upside-down.
