The Sun Hydraulics RVIDKDV (RVIDKDV) is a ventable, pilot-operated, balanced piston relief cartridge with an external drain, designed as a normally closed pressure regulating valve. It opens to tank port 2 when the inlet port 1 pressure reaches the set threshold, effectively throttling flow to maintain regulated pressure. This model features a vent port 3 for remote control and a drain port 4 that ensures insensitivity to back pressure, making it suitable for cross-port relief circuits while considering spool leakage. The main stage orifice is safeguarded by a 150-micron stainless steel screen. However, it is not recommended for load-holding applications due to potential spool leakage. This cartridge valve can handle maximum pressures at port 2 and incorporates Sun's floating style construction to minimize internal part binding from excessive installation torque or machining variations. The valve setting at port 4 adds directly to the pressure at a 1:1 ratio without exceeding 5000 psi (350 bar). Configurations with EPDM seals are specifically for systems using phosphate ester fluids, as exposure to petroleum-based substances could damage these seals. The RVIDKDV has a capacity of up to 120 gpm (480 L/min) and operates at a maximum pressure of 5000 psi (350 bar). It exhibits control pilot flow ranging from 15-20 in\u00b3/min (0.25-0.33 L/min) with typical response times around 10 ms. Maximum valve leakage stands at approximately 5 in\u00b3/min at 110 SUS (24 cSt) under an operating condition of 1000 psi (70 bar). The valve requires specific installation torques and adjustments, including an internal hex size adjustment screw of ^5\u204432 inches (4 mm), emphasizing precision in setup for optimal performance.

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.
