The Sun Hydraulics RVCSLAN (RVCSLAN) is a ventable, pilot-operated, balanced poppet relief cartridge designed for precision pressure regulation. This valve is normally closed and begins to open to tank port 2 when the pressure at inlet port 1 reaches the set level, effectively throttling flow to maintain desired pressure. The RVCSLAN features a vent port 3 that allows for remote control by other pilot or two-way valves, enhancing its versatility in various applications. Notably, it is designed to minimize issues related to cavitation such as noise and manifold erosion due to its internal modulating mechanism. This model is particularly suitable for systems utilizing phosphate ester fluids when equipped with EPDM seals; however, exposure to petroleum-based substances can damage these seals. It can handle maximum pressure at port 2 and is well-suited for cross-port relief circuits. Additionally, a remote pilot relief on the vent will enable control below the valve\u2019s preset level. The valve's performance remains stable despite fluctuations in oil temperature and contamination levels. Key specifications include a maximum operating pressure of 5000 psi (350 bar), a capacity of 15 gpm (60 L/min), and typical response time of approximately 2 milliseconds. The main stage orifice protection by a 150-micron stainless steel screen underscores its durability in load-holding applications. Furthermore, back pressure on tank port 2 directly adds to the valve setting at a 1:1 ratio. Installation considerations include using Sun's floating style construction to prevent internal binding due to installation torque or machining variations. The adjustment mechanism involves an internal hex screw with specific torque requirements for both the valve installation and locknut. Overall, the RVCSLAN offers reliable performance with easy adjustability in demanding hydraulic environments.

Description

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.
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.
Suitable for use in load holding applications.
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.

Show FAQ

Direct acting or pilot operated - what do I use?	Direct-acting valves are used to prevent over pressure, and pilot-operated valves are used to regulate pressure. If you are unsure, use a direct-acting valve. Sun's direct acting valves are very fast, dirt tolerant, stable, and robust. Sun's pilot-operated valves are moderately fast, they have a low pressure rise vs. flow curve, and they are easy to adjust.
Where would I use a kick-down relief?	One graphic example is on a portable grain auger for silos. When the farmer gets caught in the auger the kick-down relief trips and allows him to escape.
What are the tolerances on pressure settings for Sun's pressure control valves?	Pressure setting tolerances are listed in our Performance Data page. A link to this page can also be found in the Additional Resources tab of the applicable product page.
How big is a drop of hydraulic oil?	There are exactly 250 Sun drops in a cubic inch or 15 in a cc.
Can I use a kick-down relief for my system relief?	Maybe not. We build in a good amount of overlap in the kick-down reliefs to prevent false tripping. This means they are not as fast as our standard pilot-operated reliefs. A direct-acting relief valve set just above the kick-down relief valve would be good insurance.
