Proportional Valves
Continental Hydraulics offers a complete range of proportional valves: pressure control, flow control, directional, explosion-proof, high response. The various models are available with or without on-board electronic (OBE), feedback and in closed loop as well as Fieldbus and IO-Link configurations. Along with Proportional Valves, we also offer many digital electronic cards for both Open and Closed loop applications.
Efficiency, speed, accuracy, repeatability and the chance to program the control are only some of the many benefits of proportional technology on electro hydraulics applications. Moreover, proportional components allow to speed up processes while reducing wastes and errors margins.
HIGH PERFORMANCE SERVO-PROPORTIONAL
Speed and precision control
Continental Hydraulics offer Both High Speed Direct Operated NFPA D03 (NG6) and NFPA D05 (NG10) as well as High Speed Dual Feedback Pilot Operated Proportional Directional Control Valves. Two types of integrated electronics are available, with analogue or fieldbus interfaces.
- High frequency response and fast Step Response
- Nominal Flow ranges from 1 to 1000 LPM
DIRECTIONAL CONTROL WITHOUT ON-BOARD CONTROL
Robust and dependable
Continental Hydraulics offer Both Direct Operated NFPA D03 (NG6) and NFPA D05 (NG10) as well as Pilot Operated Proportional Directional Control Valves.
These valves are designed to control the direction and oil flow rate based on the amount of current supplied to the solenoid. In event of a loss in electrical power, the centering springs will return the valve spool to the center position.
The valve solenoids can be driven by a variable current power supply or by use of external Power Amplifier Cards designed to maximize the valves’ performance.
- Pressures to 5000 PSI (350 Bar)
- Din and Deutsch coil connection available
- D03 to D10 mounting sizes
DIRECTIONAL CONTROL WITH ON-BOARD CONTROL
Factory pre-set for optimal valve performance
Continental Hydraulics G Series On-Board proportional valves are offer both in Direct Operated NFPA D03 (NG6) and NFPA D05 (NG10) as well as Pilot Operated Proportional Directional Control Valves. Three types of Digital integrated electronics are available, with analog, IO-Link or fieldbus control interfaces.
- Pressure to 5000 PSI (350 Bar)
- On-Board microprocessor controls all the valve function
- D03 to D10 mounting sizes
DIRECTIONAL CONTROL WITH FEEDBACK
On-board control with spool position feedback
Continental Hydraulics J Series On-Board proportional valves with Spool Position Feedback are offered both in Direct Operated NFPA D03 (NG6) and NFPA D05 (NG10) as well as Pilot Operated Proportional Directional Control Valves. For applications requiring highly responsive and accurate motion control. Three types of Digital integrated electronics are available, with analog, IO-Link or fieldbus control interfaces.

COMPENSATED PROPORTIONAL FLOW CONTROL
Pressure compensated two and three-way proportional control
EDF03M and EDF05M are direct operated normally closed proportional flow control valves with pressure compensation.
These valves are subplate mounted according to NFPA/T.3.5.1 R2-2002 and ISO 4401:2005 standards. These valves are used to regulate flow in a hydraulic circuit. Output flow is directly proportional to the input current to the solenoid.
- Flow rate from 3 to 21 GPM
- Pressure up to 3600 PSI
- D03 and D05 Mounting sizes
PROPORTIONAL VALVES - PRESSURE CONTROL
