The Sun Hydraulics DBAPPHV (DBAPPHV) is a high-performance hydraulic valve designed for precise fluid control in various applications. This model is a pilot-stage, directional, 2-position, 3-way valve, pneumatically operated with a spring-return mechanism. It is available in two spool configurations: normally open from port 1 to port 2 and normally open from port 1 to port 3, catering to different operational requirements. The DBAPPHV features hardened spool and sleeve which ensure consistent operation, low spool leakage rates, and superior wear characteristics, enhancing the valve's reliability and longevity. The minimum pilot pressure required to operate the valve is calculated based on the pressure at Port 1, with a formula that sets the pilot pressure range between 20 to 70 psi or in metric terms, between 1.4 to 5 bar. All ports on this valve can withstand up to 5000 psi (350 bar), except for the pilot port which has a maximum capacity of 500 psi (35 bar). The valve incorporates Sun's floating style construction which minimizes potential internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. Key specifications include a capacity of .25 gpm (1 L/min), maximum operating pressure of 5000 psi (350 bar), and maximum valve leakage at high viscosity rated at approximately ten drops per minute under full pressure conditions. The DBAPPHV utilizes Viton seals for enhanced performance under varying temperature conditions and chemical exposures. This model is designed for easy integration with standard cavities (T9A) and series (P), ensuring compatibility with a wide range of hydraulic systems.
