The Sun Hydraulics RVCANCN (RVCANCN) is a ventable, pilot-operated, balanced piston relief cartridge designed as a normally closed pressure regulating valve. It effectively manages hydraulic pressure by opening to the tank port when the inlet pressure reaches a set threshold, thereby throttling flow to maintain desired pressure levels. This model features a vent port that allows for remote control via other pilot or 2-way valves, enhancing its versatility in various applications. Known for its accuracy and low-pressure rise versus flow, the RVCANCN provides smooth and quiet operation with moderate speed. Key specifications include a maximum operating pressure of 5000 psi (350 bar) and a capacity of 15 gpm (60 L/min), making it suitable for high-pressure applications. The cartridge is equipped with a main stage orifice protected by a 150-micron stainless steel screen, ensuring durability and reliability. However, it's not recommended for load holding applications due to potential spool leakage. The back pressure on the tank port directly influences the valve setting at a 1:1 ratio. This model incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations. It's configured with EPDM seals suitable for systems using phosphate ester fluids but should not be exposed to petroleum-based fluids as they can cause seal damage. Installation requires specific torque settings: valve installation torque ranges from 30 to 35 lbf ft (41 to 47 Nm), and locknut torque ranges from 80 to 90 lbf in (9 to 10 Nm). The RVCANCN weighs approximately .40 lb (.20 kg) and includes an adjustment mechanism that requires turning clockwise up to five turns to increase the setting.

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.

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.
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.
