The Sun Hydraulics RVGALGV (Material Number: RVGALGV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. This normally closed valve begins to open when the inlet port pressure reaches the preset level, allowing flow to the tank port and effectively managing system pressure. It features a vent port for remote control by other pilot or 2-way valves, offering enhanced accuracy and smooth operation with low noise levels. The valve is capable of accepting maximum pressure at port 2, making it 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, ensuring durability and reliability. This valve is not recommended for load-holding applications due to potential spool leakage. Back pressure at the tank port directly influences the valve setting at a 1:1 ratio. For systems using phosphate ester fluids, cartridges with EPDM seals are available but should not be exposed to petroleum-based substances as they can damage the seals. The Sun floating style construction minimizes internal part binding due to installation torque or machining variations. The RVGALGV fits into a Cavity T-17A and is part of the Series 3 capacity range with a maximum flow rate of 60 gpm (240 L/min) and an operating pressure up to 5000 psi (350 bar). It has a typical response time of 10 ms and maximum valve leakage at specified conditions of 4 in\u00b3/min (65 cc/min). The adjustment mechanism includes an internal hex screw with specific torque requirements for secure installation and operation. This model weighs approximately 1.60 lb (0.70 kg) and comes with an optional Viton seal kit for enhanced compatibility with various hydraulic fluids.

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.
