The Sun Hydraulics RVIDCCN (Material Number: RVIDCCN) is a ventable, pilot-operated, balanced piston relief cartridge with an external drain, designed to function as a normally closed pressure-regulating valve. When the inlet pressure at port 1 reaches the preset valve setting, it opens to tank port 2, regulating the pressure by throttling flow. This model features a vent port (port 3) for remote control by other pilot or two-way valves and a drain port (port 4) that ensures insensitivity to back pressure. The valve is known for its accuracy, low-pressure rise relative to flow, smooth operation, and moderate speed. It is capable of handling maximum pressures at port 2 and is suitable for cross-port relief circuits but not recommended for load-holding applications due to spool leakage. The main stage orifice is protected by a 150-micron stainless steel screen. The valve's operational specifications include a maximum operating pressure of 5000 psi (350 bar), with control pilot flow ranging from 15 to 20 in\u00b3/min (0.25 to 0.33 L/min). The typical response time is approximately 10 ms, and the maximum valve leakage at 110 SUS (24 cSt) is about 5 in\u00b3/min (80 cc/min) at 1000 psi (70 bar). The adjustment requires up to five clockwise turns to increase the setting and includes various hex sizes for installation and adjustment components. It incorporates Sun's floating style construction to prevent internal part binding due to excessive installation torque or machining variations. Seal kits made from Viton are available for this model; however, cartridges configured with EPDM seals should only be used with phosphate ester fluids as exposure to petroleum-based fluids can cause damage.

Description

Ventable, pilot-operated, balanced piston relief cartridges with external drain 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 and a drain (port 4) that makes them insensitive to back pressure. These valves are accurate, have low pressure rise vs. flow, they are smooth and quiet, and are moderately fast.

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.
Pressure at port 4 is directly additive to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar).
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.

Show FAQ

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.
