The Sun Hydraulics RVCACDV (RVCACDV) is a ventable, pilot-operated, balanced piston relief cartridge designed to function as a normally closed pressure regulating valve. It opens to the tank port when the inlet port pressure reaches the valve setting, effectively throttling flow to regulate pressure. This model features a vent port that allows for remote control by other pilot or 2-way valves, making it versatile for various hydraulic applications. The valve is known for its accuracy, smooth and quiet operation, moderately fast response time of approximately 10 ms, and low pressure rise compared to flow. It can handle maximum pressures up to 5000 psi (350 bar) at port 2 and is suitable for use in cross-port relief circuits; however, users should consider spool leakage when applying it in such configurations. The main stage orifice is protected by a 150-micron stainless steel screen, which ensures durability and reliability under demanding conditions. The valve's construction incorporates Sun's floating style design to minimize internal binding due to installation torque or machining variations. It is crucial to note that this model is not suitable for load-holding applications because of potential spool leakage. For fluid compatibility, cartridges with EPDM seals are intended for systems using phosphate ester fluids; exposure to petroleum-based fluids will damage these seals. The RVCACDV has a capacity of 15 gpm (60 L/min) and features an adjustable setting with up to five full clockwise turns available for increasing pressure settings. Installation requires a torque specification between 30-35 lbf-ft (41-47 Nm), ensuring secure placement within hydraulic systems. This product's design emphasizes control and adaptability while maintaining robust performance across various applications.

Description

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.

Notes:

For Series 1 cartridges configured with an O control (panel mount handknob), a .75 in. (19 mm) diameter hole is required in the panel.

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.
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.
