Sun Common RDUA Direct-acting Relief Valve
This direct-acting relief cartridge is a normally closed, pressure-limiting device used to protect hydraulic systems from over pressurization. When the pressure at the inlet (port 1) reaches the valve setting, the valve opens to tank (port 2) to prevent over pressurization. This valve is dirt-tolerant and is designed to be very fast-acting with a low rate of pressure rise.
The RDUA is a compact, economical, direct-acting relief valve. In compact mobile machinery, such as scissor lifts, the smallest and most economic solution is often requested. With a fast-acting response time, this direct-acting relief valve will clip pressure spikes with a 2ms response time.
