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, with ON/OFF control provided by the FLeX Series solenoid-operated directional valve. With the FLeX valve energized, the priority flow to CF is controlled via the adjustable needle valve. Maximum pressure to port CF can be independently adjusted with the relief. When not energized, all the flow will be diverted from port CF at 100 psi (7 bar) to port EF. The system will reach maximum pressure at maximum flow.
- Sun Priority Flow Control assemblies utilize bypass/restrictive modulating elements, when combined with an adjustable needle valve, create a bypass/restrictive flow control. Inlet flow port P is directed to the priority or control flow at port 2 to the needle valve. The after-orifice (needle 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: Fully opening the needle valve may not generate the 100-psi (7-bar) differential required to shift the bypass/restrictive modulating element allowing flow to the EF port. The needle valve will need to be adjusted to ensure bypass flow to the EF port.

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.
There are exactly 250 Sun drops in a cubic inch or 15 in a cc.
Reasons to anodize:
- To increase corrosion resistance. Sun uses 6061-T651 aluminum. It is one of the most corrosion resistant aluminum alloys there is. Whether or not anodizing improves the corrosion resistance of 6061 aluminum is debatable. We have yet to have a manifold returned because of corrosion.
- Appearance (color). The 2 colors that would appeal to Sun would be blue or black. Unfortunately these are the colors that are hardest to do consistently.
- To provide a hard wear surface. Sun does not make parts-in-body valves. The manifold is just plumbing. We don't need a wear surface.
- Because everyone else does it. Bad reason.
Reasons to not anodize:
- Cost. It's another process.
- Logistics. When you make tens of thousands of manifolds a month and you anodize hundreds, it's a problem. Consistency. See above.
- Stamping. After a body is anodized you cannot do any more stamping without making a mess.
Inspection. Have you ever tried to look for burrs in a black anodized body? It's the old blackboard factory at night scenario. - Torque. You will experience an increase in breakaway torque when removing items from an anodized manifold.
- Fatigue life. This is the best reason to not anodize. Fatigue failure is a very complex phenomenon. What it takes to initiate a crack is difficult to predict. What it takes to propagate a crack is readily defined. Anodizing produces a very thin, very hard, and very brittle surface on aluminum. The first time you pressurize an anodized aluminum manifold you have initiated fatigue cracks. Whether or not the stress is enough to propagate the cracks is a matter of pressure and manifold geometry. Anodizing an aluminum manifold grossly reduces the fatigue life by anywhere from 20% to 50%.
- 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.
