All our coils for solenoid and proportional cartridge valves are robust, compact and PLUS+1™ Compliant.
We have coils for all valve sizes and in various connector types and voltages. In addition to our standard range, our robust coils are made to tolerate the extremes – whether voltage, temperature or water ingression due to power spray or submersion. And, thanks to the robust coil design, there is no need for o-rings around the coil.
Our PLUS+1 Compliant coils equip our valves for seamless integration in our powerfully intelligent mobile control systems.

Solenoid valves are electrically-operated, on-off poppet or spool-type valves for load holding, blocking, or directional control applications.
Comatrol solenoid valves are PLUS+1™ compliant. PLUS+1 compliance means our valves are directly compatible with the PLUS+1 machine control architecture. Adding solenoid valves to your application using PLUS+1 GUIDE software is as easy as drag-and-drop. Software development that used to take months can now be done in just a few hours. For more information on PLUS+1 GUIDE, visit www.comatrol.com or www.sauer-danfoss.com/plus1. The table below details available GUIDE function blocks for controlling Comatrol solenoid valves.

flow control valves
Pressure compensated flow control valves are used to limit or regulate flow.
Three basic types of cartridges are available; restrictive-type, priority-type, and divider/combiner type.
Combination valves in manifolds for additional features such as fully adjustable flow or free reverse flow are also available.
Restrictive-type pressure compensated flow control valves are two-ported valves that maintain a constant flow rate from 1 to 2 regardless of load pressure changes in the circuit downstream of 2. The control orifice in the spool is factory set to the flow specification. The valve begins to respond to load changes when flow through the valve creates a pressure differential across the control orifice of approximately 7 bar [100 psi], and accurately maintains flow within +/- 10% across the range of 35‑207 bar [500‑3000 psi]. Reverse flow from 2 to 1 returns through the control orifice and is non-compensated.
Restrictive-type flow control valves can be used in meter-in or meter-out applications to control actuator speeds.
