The Sun Hydraulics RVEDLDV (RVEDLDV) is a ventable, pilot-operated, balanced piston relief cartridge with an external drain, designed for precise pressure regulation. It remains normally closed and opens to the tank port when the inlet pressure reaches the valve setting, effectively throttling flow to maintain pressure levels. This model features a vent port for remote control via other pilot or 2-way valves and a drain port that ensures insensitivity to back pressure. The RVEDLDV is known for its accuracy, low-pressure rise versus flow, smooth operation, quiet performance, and moderate response speed. It can handle maximum pressures at port 2 and is suitable for cross-port relief circuits; however, users should consider spool leakage in such applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen but is not recommended for load-holding applications due to potential spool leakage. Pressure at port 4 directly adds to the valve setting on a 1:1 ratio and should not exceed 5000 psi (350 bar). The cartridge is compatible with EPDM seals for use in systems that utilize phosphate ester fluids; exposure to petroleum-based fluids can cause seal damage. Adjustment controls (W and Y) allow full-range settings unless a special setting limits the maximum adjustment. The valve incorporates Sun's floating style construction to minimize internal binding risks during installation or due to machining variations. Additional specifications include a cavity size of T-22A, series 2 capacity of up to 30 gpm (120 L/min), factory pressure settings established at 4 gpm (15 L/min), maximum operating pressure of 5000 psi (350 bar), and typical response time of 10 ms. Valve installation requires specific torque settings and hex sizes as outlined in its technical details.
