The Sun Hydraulics RVGSLAV (RVGSLAV) is a ventable, pilot-operated, balanced-poppet relief cartridge designed for precise pressure regulation in hydraulic systems. This normally closed valve begins to open when the inlet port 1 reaches the designated setting, allowing flow to the tank port 2 to regulate pressure effectively. It features a vent port 3 that facilitates remote control via other pilot or 2-way valves. Known for its accuracy and low pressure rise relative to flow, this valve operates smoothly and quietly with moderate speed. Its internal modulation makes it resistant to cavitation-related issues such as noise and manifold erosion. Ideal for load-holding applications, it requires zero-leak valving on the vent port for optimal performance. The RVGSLAV is compatible with cross-port relief circuits and can handle maximum pressure at port 2. It remains stable across varying oil temperatures and contamination levels, thanks to its main stage orifice protected by a 150-micron stainless steel screen. The valve's floating style construction minimizes internal part binding due to excessive installation torque or machining variations in the cavity/cartridge. Key specifications include a capacity of 50 gpm (200 L/min), maximum operating pressure of 5000 psi (350 bar), and typical response time of 2 ms. It features a factory pressure setting established at 4 gpm (15 L/min) and control pilot flow between 15-20 in\u00b3/min (0.25-0.33 L/min). The valve has a hex size of 1\u00bc inches (31.8 mm) with an installation torque range of 150-160 lbf\u00b7ft (203-217 Nm). The adjustment screw has an internal hex size of ^5/32 inches (4 mm), while the locknut hex size is ^9/16 inches (15 mm) with a torque range of 80-90 lbf\u00b7in (9-10 Nm). Weighing approximately 1.60 lb (0.70 kg), this valve can be configured with EPDM seals for use in systems utilizing phosphate ester fluids but should avoid exposure to petroleum-based substances.

Ventable, pilot-operated, balanced-poppet 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.
- Because the modulating occurs inside the cartridge, these valves are immune to most of the problems associated with cavitation, namely noise and manifold erosion.
- Suitable for use in load holding applications, providing that any valving on the vent port (port 3) is zero leak.
- 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.
- Will accept maximum pressure at port 2; suitable for use in cross port relief circuits.
- A remote pilot relief on port 3 (vent) will control the valve below its own setting.
- Valve is relatively insensitive to varying oil temperatures and oil borne contamination.
- Main stage orifice is protected by a 150 micron stainless steel screen.
- Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio.
- 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.
