The Sun Hydraulics RVGALKV (RVGALKV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation. This normally closed valve begins to open to tank port 2 when the inlet pressure at port 1 reaches the preset level, thereby throttling flow and regulating pressure. A unique feature of this cartridge is its vent port 3, which allows for remote control by other pilot or two-way valves. Known for its accuracy and smooth operation, it offers low pressure rise versus flow and moderate response speed. The RVGALKV can handle maximum pressure at port 2, making it suitable for cross-port relief circuits; however, users should consider spool leakage in such applications. It is not designed for load-holding scenarios due to potential leakage issues. The main stage orifice is protected by a 150-micron stainless steel screen to ensure durability and reliability. It can accommodate systems using phosphate ester fluids when equipped with EPDM seals but should avoid petroleum-based fluids as they can damage these seals. The valve employs Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. This model fits into Cavity T-17A and has a flow capacity of up to 60 gpm (240 L/min) with a maximum operating pressure of 5000 psi (350 bar). The control pilot flow ranges from 15-20 in\u00b3/min (0.25-0.33 L/min), with a typical response time of around 10 milliseconds. Maximum valve leakage at 110 SUS (24 cSt) is approximately 4 in\u00b3/min at 1000 psi (65 cc/min at 70 bar). Installation requires specific torques: the valve hex size is 1\u00bc inch (31.8 mm), requiring an installation torque between 150-160 lbf ft (203-217 Nm), while adjustment screws and locknuts have their respective specifications for optimal performance.

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.
- Not suitable for use in load holding applications due to spool leakage.
- Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio.
- 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.
