The Sun Hydraulics RVCANBV (Material Number: RVCANBV) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. This valve remains normally closed and opens to the tank port when the inlet pressure reaches the set threshold, effectively throttling flow to maintain desired pressure levels. A key feature is its vent port, which allows for remote control by other pilot or two-way valves. The RVCANBV is noted for its accuracy, low pressure rise versus flow characteristics, smooth operation, and moderate speed. It can handle maximum pressures at port 2 and is suitable for cross-port relief circuits; however, users should consider spool leakage in these configurations. This model incorporates a main stage orifice protected by a 150-micron stainless steel screen and is not recommended for load-holding applications due to potential spool leakage. The back pressure on the tank port directly affects the valve setting at a 1:1 ratio. Cartridges with EPDM seals are intended for systems using phosphate ester fluids and should avoid exposure to petroleum-based substances to prevent seal damage. The valve features Sun's floating style construction to reduce internal binding risks caused by installation torque or machining variations. Technical specifications include a T-11A cavity configuration with Series 1 capacity of 15 gpm (60 L/min), maximum operating pressure of 5000 psi (350 bar), and typical response time of 10 ms. The control pilot flow ranges from 7-10 in\u00b3/min (0.11-0.16 L/min), with a maximum valve leakage of 2 in\u00b3/min (30 cc/min) at specific conditions. Adjustment involves up to five clockwise turns to increase settings, with specific torque requirements for installation and locknut adjustments provided for optimal performance.

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.
