Sun Hydraulics DRBCCEV/AP 换向阀
DRBCCEV/AP - 3-way, direct-acting, directional valve with internal drain to port 3 (1 blocked, 2 to 3 open)
Sun Hydraulics
Direct-acting, 3-way directional cartridges (1 blocked, 2 to 3 open) are switching devices typically used in moderate flow circuits. They can be used by themselves or to actuate larger pilot-operated directional cartridges or logic cartridges. The valve shifts when the pressure differential between port 1 and port 3 exceeds the setting. Pressure at port 3 is directly additive to the setting of the valve. Because of this, port 3 may not be useable as a work port in your circuit. If this is a consideration, the 4 port version of this valve may be a solution. Because of their direct-acting design, these cartridges feature low internal leakage and low pilot flow consumption. Direct-acting and pilot-operated versions of these valves are interchangeable. They fit the same cavities and have the same flow paths. This valve is not bistable; it is capable of modulating between the two positions shown. 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.

There are exactly 250 Sun drops in a cubic inch or 15 in a cc. I used a DP** in a circuit but it hangs. What happened? DP**s and DR**s are from the reducer/reliever family and are very capable of modulating. They are not bistable. Where would I use a DR__ instead of a DP__? In many circuits the directional cartridge is set to shift at a low pressure no matter how high the pilot pressure goes. If you use a DP__ , the pilot flow increases to significant amounts. A DR__ however will only consume a small amount of flow. A DP__ is useful when you want to block or open the pilot flow to shift the valve. Direct acting, 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.
