2 Voies, 2-stage, électro distributeur Clapet Valve - common cavity
![DGVA : 2 Voies, 2-stage, électro distributeur Clapet Valve - common cavity](https://cmsimages.sunhydraulics.com/cartg_DGVA.gif)
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.
- L’ensemble du doigt de gant du solénoïde est dimensionné pour fonctionner à 350 bar, hors limite de fatigue.
- All ports are rated to a maximum operating pressure of 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).
- The valve is available with a manual unscrew-type override option (L control) on the normally closed configuration. This option is also fatigue rated for 5000 psi (350 bar).
- The metal coil nut is a functional feature of the valve and should be correctly installed for proper performance of the valve.
- Coil connector options offer ratings up to IP67. See individual coil product pages for details.
- Coils can be mounted on the tube in either direction.

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.
