This assembly provides an efficient way to supply auxiliary hydraulic power to various systems. The assembly divides the inlet flow of port P into a priority flow to port CF with excess flow to port EF. It provides electro-proportional priority bypass flow control using the FP*K electro-proportional throttle valve with reverse flow check. When the FP*K valve is given a proportional command signal, the output of the controlled priority port will start to increase proportionally to the signal provided. The LH*A priority valve (a bypass/restrictive priority modulating element) will act as a pressure compensator to ensure that the flow to port CF will remain constant during pressure changes. This will allow for very stable, continuous flow for a given command signal to control even the most demanding applications like hydraulic hammers and rock breakers. The FP*K valve will provide optimal performance when combined with a factory-tuned XMD driver.
- Model FP*K can be configured with Sun's coil mounted XMD driver. Mounting holes are also available for user to assemble an XMD driver to the manifold.
- Sun Priority Flow Control assemblies utilize bypass/restrictive modulating elements, and when combined with FP*K electro-proportional throttle valve, create a bypass/restrictive flow control. Inlet flow port P is directed to the priority or control flow at port 2 to the FP*K electro-proportional throttle valve. The after-orifice (FP*K electro-proportional throttle valve) signal is connected to port 1. Once the priority requirements are met, excess flow is bypassed to the EF.
- The bypass/restrictive modulating element (LH*A) requires 100-psi (7-bar) differential pressure across the throttle valve before modulating to allow flow to EF port.
- Note: Full command signal to the FP*K throttle valve may not generate the 100-psi (7-bar) differential required to shift the bypass/restrictive modulating element allowing flow to the EF port.

There are exactly 250 Sun drops in a cubic inch or 15 in a cc.
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.
- Important: Carefully consider the maximum system pressure. The pressure rating of the manifold is dependent on the manifold material, with the port type/size a secondary consideration. Manifolds constructed of aluminum are not rated for pressures higher than 3000 psi (210 bar), regardless of the port type/size specified.
