The Sun Hydraulics RVCDKEN (RVCDKEN) is a ventable, pilot-operated, balanced piston relief cartridge with an external drain, designed to function as a normally closed pressure regulating valve. When the inlet port pressure reaches the designated valve setting, it begins to open to the tank port, effectively throttling flow to regulate pressure. This model features a vent port that allows for remote control by other pilot or two-way valves and includes a drain port that renders it insensitive to back pressure. It offers precision with low pressure rise versus flow and operates smoothly and quietly with moderate speed. The RVCDKEN can handle maximum pressure at port 2, making it suitable for cross-port relief circuits, though spool leakage should be considered in such applications. It is not recommended for load-holding applications due to potential leakage. The main stage orifice is protected by a 150-micron stainless steel screen. The valve's performance includes a cavity T-21A series 1 capacity of 15 gpm (60 L/min), with factory pressure settings established at 4 gpm (15 L/min). It has a maximum operating pressure of 5000 psi (350 bar) and control pilot flow ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min). Typical response time is around 10 ms, with maximum valve leakage at 110 SUS (24 cSt) being approximately 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). The adjustment mechanism involves up to five clockwise turns to increase the setting, with specific torque requirements for installation and adjustment components provided. This model is equipped with EPDM seals suitable for systems using phosphate ester fluids but should not be exposed to petroleum-based substances. Additionally, it incorporates Sun\u2019s floating style construction which minimizes internal binding risks due to installation variances or machining discrepancies.
