The Sun Hydraulics DODSXHV (DODSXHV) is a high-performance, normally open, balanced poppet switching element designed for advanced hydraulic systems. This valve shifts to a closed position when pilot pressure is applied at port 3, offering precise control in demanding applications. Its unique balanced construction ensures reliable operation with pressures up to 5000 psi (350 bar) at both ports 1 and 2, while maintaining an external drain open. The valve requires a minimum pilot pressure of 400 psi (28 bar) to shift and will reopen when pilot pressure drops below 145 psi (10 bar). Key features include hydraulic balancing between port 1 and port 2, with both ports fully sealed from ports 3 and 4 to prevent cross-contamination. The valve's design minimizes internal leakage, typically less than 10 drops per minute at maximum operating pressure. All ports are capable of handling pressures up to 5000 psi (350 bar), ensuring robust performance in high-pressure environments. The Sun floating style construction reduces the risk of internal parts binding due to installation torque or machining variations. The DODSXHV fits into a T21A cavity and belongs to Series 1, with a flow capacity of up to 15 gpm (60 L/min). It requires precise installation torque between 30-35 lbf ft (41-47 Nm) and has a compact model weight of .35 lb (.15 kg). A Viton seal kit is available for enhanced durability. This valve is ideal for applications requiring dependable switching under high-pressure conditions, offering low leakage rates and consistent performance across various hydraulic systems.
