The Sun Hydraulics RVESLQN (RVESLQN) is a ventable, pilot-operated, balanced-poppet relief cartridge designed to function as a normally closed pressure regulating valve. When the inlet port pressure reaches a predetermined setting, the valve opens to the tank port, regulating flow to maintain consistent pressure levels. This model features a vent port that allows for remote control by other pilot or 2-way valves, making it highly versatile for various hydraulic systems. The RVESLQN is known for its accuracy and low-pressure rise versus flow characteristics, ensuring smooth and quiet operation with moderate response speed. Its design effectively mitigates issues related to cavitation, such as noise and manifold erosion. Ideal for load-holding applications with zero-leak valving on the vent port, this valve can handle maximum pressure at port 2 and is suitable for cross-port relief circuits. It also allows remote pilot relief control on the vent port to manage the valve below its set threshold. Notably insensitive to oil temperature variations and contamination, the main stage orifice is safeguarded by a 150-micron stainless steel screen. The back pressure on the tank port directly adds to the valve setting at a 1:1 ratio. The RVESLQN incorporates Sun's floating style construction to minimize potential binding of internal components due to installation torque or machining variations. Key specifications include a capacity of 25 gpm (95 L/min), maximum operating pressure of 5000 psi (350 bar), and typical response time of 2 ms. It features an adjustment range with five clockwise turns to increase settings, along with specific torque requirements for installation and adjustments. The cartridge's robust design and performance make it suitable for demanding hydraulic applications requiring reliable pressure regulation.

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.
- 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.
