The Sun Hydraulics RVIAKEV (RVIAKEV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation. This normally closed valve opens to the tank port when the inlet pressure reaches a predetermined setting, effectively throttling flow to manage pressure levels. It features a vent port that allows for remote control by other pilot or 2-way valves. Known for its accuracy and smooth operation, this valve exhibits low pressure rise relative to flow and operates quietly with moderate speed. The valve can handle maximum pressure 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 protected by a 150-micron stainless steel screen. This cartridge employs Sun's floating style construction to reduce the risk of internal binding due to installation torque or machining discrepancies. It is important to note that cartridges configured with EPDM seals are intended for use with phosphate ester fluids only, as petroleum-based fluids can damage these seals. Notably, this valve is not appropriate for load-holding applications due to potential spool leakage. The RVIAKEV has a cavity size of T-19A and belongs to Series 4 with a capacity of 120 gpm (480 L/min). It operates at a maximum pressure of 5000 psi (350 bar) with control pilot flow ranging from 15 to 20 in\u00b3/min (0.25 to 0.33 L/min) and typical response time of 10 ms. Maximum valve leakage at standard conditions is specified as 5 in\u00b3/min (80 cc/min). The adjustment mechanism requires up to five clockwise turns for setting increases, with specific torque requirements detailed for installation and locknut adjustments.

Ventable, pilot-operated, balanced piston relief cartridges are normally closed pressure regulating valves. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open to tank (port 2), throttling flow to regulate the pressure. They provide a vent port (port 3) that connects between the main piston and pilot stage to provide for remote control by other pilot or 2-way valves. These valves are accurate, have low pressure rise vs. flow, they are smooth and quiet, and are moderately fast.
- A remote pilot relief on port 3 (vent) will control the valve below its own setting.
- Will accept maximum pressure at port 2; suitable for use in cross port relief circuits. If used in cross port relief circuits, consider spool leakage.
- Main stage orifice is protected by a 150 micron stainless steel screen.
- Relief valve setting must always be higher than pilot valve setting.
- Not suitable for use in load holding applications due to spool leakage.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
