The Sun Hydraulics FPCCMAV812 (FPCCMAV812) is a normally-closed, electro-proportional throttle valve designed to provide precise flow control in hydraulic systems. This valve is spring-biased closed, and energizing the coil generates an opening force on the spool proportional to the command current. This force is countered by the spring and flow forces, creating a metering orifice whose effective size is proportional to the current. The FPCCMAV812 valve offers self-compensation in the 1 to 2 direction and can provide proportional flow control in the 2 to 1 direction with an external compensator. It allows full reverse flow from 2 to 1 with full command without a compensator under all conditions. Available in normally open or closed configurations, this model supports three different capacity ranges and operates at pressures up to 5000 psi. It features low leakage levels when closed and interchangeable coils that can be mounted in either direction on Sun's other solenoid-operated valves. For optimal performance, it's recommended to use an amplifier with current sensing and adjustable dither between 100-250 Hz. The FPCCMAV812 also includes several manual override options for flexibility, including a momentary-twist option that allows manual shifting of the valve by twisting clockwise 90 degrees. The cartridge incorporates Sun's floating style construction, minimizing internal part binding due to excessive installation torque or machining variations. With a capacity of up to 10 gpm (40 L/min), this valve model fits into cavity T-13A and requires specific installation torque parameters for proper function. Additionally, it supports EPDM seals for compatibility with phosphate ester fluids while being vulnerable to petroleum-based substances.

This valve is a normally-closed, electro-proportional throttle. The valve is spring biased closed. Energizing the coil generates an opening force on the spool proportional to the command current and this force is countered by the spring and flow forces. This force balance creates a metering orifice whose effective size is proportional to the current. The valve exhibits a large degree of self-compensation in the 1 to 2 direction and will provide proportional flow control in the 2 to 1 direction with the addition of an external compensator. Full reverse flow (2 to 1) with 100% command in the 2 to 1 direction is possible without a compensator under all conditions.
- Available in either a normally open or normally closed configuration with three different capacity ranges.
- Capable of operating with pressures up to 5000 psi.
- Low leakage levels in the closed position.
- Coils are interchangeable with Sun's other full flow, solenoid-operated valves and can be mounted on the tube in either direction.
- This cartridge has several manual override choices, including no manual override. See Option Configuration.
- For optimum performance, an amplifier with current sensing and adjustable dither should be used. Dither should be adjustable between 100 - 250 Hz.
- On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, E, L and T manual control assemblies have a mechanical life expectancy of approximately 7,000 cycles.
- The momentary/twist override option "E" allows the operator to shift the valve by twisting the manual override clockwise 90 degrees.
- Cartridges 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.
