The Sun Hydraulics PD16-44-0-N-110 is a high-performance, pilot-operated, spool-type proportional pressure reducing/relieving valve. This normally open cartridge valve is engineered to regulate pressure in a hydraulic circuit by reducing a high primary pressure at the inlet (port 2) to a consistently lower pressure at the regulated port (port 1). The regulated pressure is directly proportional to the electrical current applied to the solenoid coil. This valve also functions as a relieving valve, protecting the secondary circuit from pressure spikes by diverting flow from port 1 to the tank (port 3). Designed for the T-16A cavity, this model is robust and provides precise, stable pressure control for demanding applications. Please note, this specific model is supplied without a coil.
