The Sun Hydraulics RVGSCCN (RVGSCCN) is a ventable, pilot-operated, balanced poppet relief cartridge designed for precise pressure regulation in hydraulic systems. This normally closed valve opens to the tank port when the inlet pressure reaches the preset level, effectively throttling flow to maintain desired pressure levels. It features a vent port that allows for remote control via other pilot or 2-way valves, enhancing its versatility. Notably accurate and stable, this valve exhibits low pressure rise relative to flow and operates smoothly and quietly. The internal modulation of the cartridge makes it resistant to cavitation-related issues like noise and manifold erosion. The RVGSCCN is suitable for load holding applications, provided any valving on the vent port is zero leak. It can handle maximum pressure at port 2 and is appropriate for cross-port relief circuits. A remote pilot relief can be used on the vent port to control the valve below its own setting. The valve's performance remains consistent despite variations in oil temperature or contamination levels, thanks to its robust design that includes a main stage orifice protected by a 150-micron stainless steel screen. This model incorporates Sun's floating style construction, reducing the risk of internal part binding due to excessive installation torque or machining variations. It supports up to 50 gpm (200 L/min) capacity with a maximum operating pressure of 5000 psi (350 bar). The factory pressure settings are established at 4 gpm (15 L/min), with typical response times around 2 ms. The valve has minimal leakage upon reseat and features adjustable settings with specific torque requirements for installation and adjustment components. This component weighs approximately 1.60 lb (0.70 kg) and comes with an available Viton seal kit for enhanced compatibility with various fluids.

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.
Suitable for use in load holding applications, providing that any valving on the vent port (port 3) is zero leak.
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.
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.
