The Sun Hydraulics RVGELDN (RVGELDN) is a fast-acting, ventable, pilot-operated, balanced piston relief cartridge designed for efficient pressure regulation in hydraulic systems. This normally closed valve opens to the tank port when the inlet pressure reaches the set threshold, throttling flow to maintain desired pressure levels. It features a vent port that allows for remote control by other pilot or two-way valves, making it versatile for various applications. The valve can handle maximum pressure at port 2 and is suitable for cross-port relief circuits, though spool leakage should be considered in such configurations. Its main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability. However, it is not recommended for load-holding applications due to potential spool leakage. The RVGELDN incorporates Sun's floating style construction to minimize internal binding from excessive installation torque or machining variations. It has a cavity of T-17A with a series 3 capacity of 60 gpm (240 L/min) and can operate at a maximum pressure of 5000 psi (350 bar). The control pilot flow ranges between 15-20 in\u00b3/min (0.25-0.33 L/min) with a typical response time of 2 ms. Maximum valve leakage at 110 SUS (24 cSt) is rated at 4 in\u00b3/min under 1000 psi (65 cc/min at 70 bar). The adjustment mechanism requires approximately five turns clockwise to increase the setting, with specific hex sizes designated for installation and adjustment purposes. This model weighs approximately 1.60 lbs (0.70 kg) and utilizes Viton seals as part of its construction kit. The RVGELDN is ideal for applications requiring precise pressure control and quick response times while maintaining robustness against varying operational conditions.

Description

Fast-acting, 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 have low pressure rise vs. flow and are very 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.
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.
