The Sun Hydraulics RVID8DV (RVID8DV) is a versatile hydraulic valve designed for modulating pressure control in various applications. This normally closed modulating element features an integral pilot control cavity, allowing it to accept any T8A pressure control cartridge for precise pressure regulation. It operates with a balanced piston design and is ventable and externally drained, making it suitable for use in cross port relief circuits. The valve begins to open to tank port 2 when the inlet port 1 reaches the pilot control cartridge setting, effectively throttling flow to maintain desired pressure levels. 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 spool leakage. The valve's construction includes Sun's floating style design, minimizing the risk of internal parts binding from excessive installation torque or machining variations. The maximum operating pressure at port 4 should not exceed 5000 psi (350 bar), with the pressure at this port being directly additive to the valve setting at a 1:1 ratio. Installation requires specific torque values: the main stage valve should be installed first, followed by the T8A pilot control valve into its designated cavity. The RVID8DV supports various pilot control cartridges sold separately, including electroproportional, solenoid, air pilot, and hydraulic pilot options. With a capacity of 120 gpm (480 L/min) and typical response time of 10 ms, this valve provides reliable performance in demanding environments. Its compact design features a hex size of 1-5/8 inches (41.3 mm) for the main stage and weighs approximately 3.10 lb (1.40 kg).

This valve is a normally closed modulating element that incorporates an integral pilot control cavity. It is ventable, externally drained, and is a balanced piston design. The pilot control cavity will accept any T-8A pressure control cartridge. When the pressure at the inlet (port 1) reaches the pilot control cartridge setting, the modulating element starts to open to tank (port 2), throttling flow to regulate the pressure. The pilot cartridge's setting determines the difference in pressure between the inlet (port 1) and the drain (port 4). The vent port (port 3) that tees in between the main piston and pilot control cartridge, allows the modulating element to also be controlled by remote pilot or 2-way valves.
- Will accept maximum pressure at port 2; suitable for use in cross port relief circuits.
- 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).
- NOTE: With the -8 control option, the main stage valve should first be installed to the correct torque value. The T-8A pilot control valve should then be installed into the main stage valve to its required torque value.
- The -8 control option allows the pilot control valve to be incorporated directly into the end of the relief cartridge via the T-8A cavity. These pilot control cartridges are sold separately and include electro-proportional, solenoid, air pilot, and hydraulic pilot operation. See Pilot Control Cartridges.
- 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.
