This valve is a solenoid-operated 3-position, 4-way proportional directional valve spring centered to the neutral position. It is available with a Blocked Center condition or an A and B Bleed to T Center condition. The flow from Port 3 (P) to Port 2 (B) and from Port 4 (A) to Port 1 (T) increases proportionally to the current applied to coil A. The flow from Port 3 (P) to Port 4 (A) and from Port 2 (A) to Port 1 (T) increases proportionally to the current applied to coil B.
- Cette valve est à action directe et ne nécessite pas de minimum de pression hydraulique pour fonctionner.
- There are three flow ranges for each center configuration. See performance curves for more information.
- For best performance, an amplifier with current sensing and adjustable dither should be used. Reported performance is at recommended dither.
- Recommended dither varies per spool type (see proportional performance data) and may be adjusted to better suit the application.
- For best stability and control, recommended use is with a properly-sized restrictive (LPDC) or bypass (LRDC) compensator. Provisions to dampen the load-sense line of the compensator may be helpful in achieving the best performance.
- Self-compensated use is possible to a degree. Please refer to performance curves for details. For more precise flow control consider a separate compensator.
- Use of this valve with its 12V coil variants (778212 and 778912D) yields a lower rated performance when operating the coil at a 100% duty cycle. See performance curves for details.
- Port 1 (Tank) is rated to a maximum of 1000 psi (70 bar). All other ports are rated to a maximum operating pressure of 3600 psi (250 bar).
- The valve is available with a manual override option (T control). This hand-actuated lever option is also rated to a maximum of 1000 psi (70 bar) at Port 1 and can be actuated under pressure. Rotating the lever away from the manifold block will connect port 3 to port 4 and port 2 to port 1. Rotating the lever towards the manifold block will connect port 3 to port 2 and port 4 to port 1.
- The manual override option includes two mounting bolts which fasten the mechanism onto the valve via mounting holes on the manifold. For details on the mounting holes, refer to the product page of any Sun manifold configured with an SC-10-04 cavity (i.e. model code: JPA).
- 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.
- Le noyau du solénoïde est à bain d’huile, ce qui signifie que le fluide du système, qui entoure le noyau, est soumis à la chaleur générée par la bobine. Il faut en tenir compte dans les cas où la bobine est excitée pendant une durée prolongée. Certains fluides, notamment les mélanges eau/glycol, se détériorent à ces températures et avec le temps, des vernis se forment et peuvent affecter le fonctionnement de la cartouche.
- The cartridge installation torque of 30 lbf ft (40 Nm) is required for best performance.
- 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.
