The Sun Hydraulics RVESLBV (RVESLBV) is a ventable, pilot-operated, balanced poppet relief cartridge designed to function as a normally closed pressure regulating valve. This specialized valve opens to tank port 2 when the inlet port 1 pressure reaches the set threshold, effectively throttling flow to maintain regulated pressure. It features a vent port 3 that enables remote control via other pilot or two-way valves, making it highly versatile for various applications. The RVESLBV is known for its accuracy, low pressure rise versus flow, smooth operation, quiet performance, and moderate speed. One of its key advantages is its immunity to cavitation-related issues such as noise and manifold erosion due to internal modulating. This valve is suitable for load-holding applications provided that any valving on vent port 3 ensures zero leakage. It can handle maximum pressure at port 2 and is ideal for cross-port relief circuits. Additionally, a remote pilot relief on the vent will control the valve below its own setting. The RVESLBV remains relatively insensitive to changes in oil temperatures and contamination within the oil. Its main stage orifice is safeguarded by a 150-micron stainless steel screen. The valve's design incorporates Sun's floating style construction to minimize potential binding of internal parts due to excessive installation torque or cavity/cartridge machining variations. With a capacity of 25 gpm (95 L/min) and maximum operating pressure of 5000 psi (350 bar), it offers reliable performance in demanding environments. The valve features a response time of approximately 2 ms and has minimal leakage at reseat with only 10 drops/min (0.7 cc/min). Installation requires specific torque settings and adjustments are made via an internal hex screw with a locknut for secure positioning.

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.
