This solenoid-operated, 2-way, 2-position cartridge is a pilot-operated, directional poppet valve. This valve offers 2-position, 2-way directional control with a lower pressure drop than its direct-acting counterpart. The valve is available in the normally open and normally closed condition.
- 电磁铁组件的疲劳耐压等级为5000 psi (350 bar)。
- 所有油口最大工作压力都为5000 psi (350 bar)。
- This valve is not suitable for load-holding. Up to 9 in3/min (147 mL/min) of leakage is allowed when below a pressure differential of 1000 psi (70 bar) between its ports.
- The cartridge installation torque of 37 lbf-ft (50 Nm) is required for best performance.
- The valve is available with a manual push-type, with detent, override option (L control) on the normally open configuration. This option is also fatigue rated for 5000 psi (350 bar).
- 该阀常闭选项可提供旋开形式的手动操控(L控制)。该选项疲劳耐压等级为5000 psi (350 bar)。
- 金属线圈螺母为电磁功能的一部分,其应当正确安装到位以保证阀的正常功能。
- 线圈接头选项提供最高IP67的防护等级。详见线圈产品页面。
- 线圈可以双向安装到螺线管上。

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.
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.
