Product Description
Proportional directional valve |
|
 |
Parker direct acting proportional directional valve D * FW/D * FT seriesThe direct acting (D * FW) directional valve series with nominal sizes CETOP3 and CETOP5 is a proportional valve used for flow control. The valve (D * FW) is electrically controlled using PWD-400/PCD-400 power amplifiers or integrated electronic components are plugged into the valve to form a whole (D * FT). A typical application is that by adjusting the ramp signal, the valve core can be gently reversed to reduce hydraulic and mechanical impacts, and mechanical function automation can be achieved by electrically adjusting the flow/speed. |
 |
Parker direct acting proportional directional valve D * FL seriesThe D * FL series valves with nominal sizes CETOP3 and CETOP5 are digital proportional valves used for flow control. This type of 4-way valve controlled by a microprocessor can adjust different given speeds through power distribution signals. Acceleration, deceleration, and speed can be adjusted on the valve. The typical fast/low-speed travel characteristics can be achieved without the need for other modules. |
 |
Parker direct acting proportional directional valve WL * NG06 seriesThe WLL series direct acting proportional valve with nominal size CETOP3 is used to control flow. The valve (D * FW) adopts Euro card standard VDR350/355 digital power amplifier or PWD-400/PCD400 power amplifier module for electronic control. Typical applications include precise and achievable flow control, fast/low-speed stroke characteristic control, and positioning of hydraulic transmission devices. |
 |
Parker direct acting proportional directional valve WL * NG10 seriesThe WLL series direct acting proportional valve with a nominal size of CETOP5 is used to control flow. The valve (D * FW) adopts Euro card standard VDR350/355 digital power amplifier or PWD-400/PCD400 power amplifier module for electronic control. Typical applications include precise and achievable flow control, fast/low-speed stroke characteristic control, and positioning of hydraulic transmission devices. |
 |
Parker direct acting proportional directional valve D * FX seriesThe direct acting D * FX directional valve series with nominal sizes CETOP3 and CETOP5 is a proportional valve used for flow control. Typical applications include precise flow control and the ability to achieve flow regulation, as well as the improvement of working characteristics under fast and low-speed conditions, soft acceleration, and deceleration. |
 |
Parker Direct Acting Proportional Directional Valve RLL SeriesThe RLL series direct acting proportional valve with nominal size NG06 (CETOP 3) is used to control flow. The valve is electronically controlled using a VRD350/355 digital power amplifier with Euro card specifications. Typical applications include precise and reproducible flow regulation, control of fast/low-speed travel characteristics, and dynamic closed-loop position adjustment. |
 |
Parker direct acting proportional directional valve D * FH/D1FM seriesThe D * FH and D1FM series proportional directional valves with nominal sizes of CETOP3 and CETOP5 are used to control flow. This valve is a high dynamic characteristic regulating valve with integrated electronic components. Its typical application is precise and dynamic position adjustment. |
 |
Parker Pilot Proportional Directional Valve D * 1FW/D * 1FT SeriesThe D * 1FW and D * 1FT series pilot operated proportional directional valves with nominal sizes of CETOP5 and CETOP10 are used to control flow. The valve (D * 1FW) is electrically controlled using a PWD-400 power amplifier or integrated electronic components are plugged into the valve to form a whole (D * 1FT). A typical application is that by adjusting the ramp signal, the valve core can be gently reversed to reduce hydraulic and mechanical impact, and the automation of mechanical functions can be achieved by electrically adjusting the flow/speed. |
 |
Parker Pilot Proportional Directional Valve D * 1FS SeriesThe D * 1FS series pilot operated proportional directional valves with nominal sizes ranging from CETOP3 to CETOP10 are used to control flow. The valve is electrically controlled using EW series analog power amplifiers or VRD350/355 digital power amplifiers. The position of the main valve core can be adjusted. Typical applications include precise flow control and the ability to achieve flow regulation, as well as improvements in fast/low-speed operation, soft acceleration, and delayed operation characteristics. |
 |
Parker D41FH series pilot operated proportional directional valveThis series of pilot operated proportional directional valves is used to control flow. This valve has integrated electronic components, and the position of the main stage valve core is adjustable. A typical application is: precise flow control and achievable flow regulation, with valve core position monitoring for fast/low-speed operation, used for press control, dynamic position adjustment, and pressure/flow closed-loop systems. Technical features: small leakage, high frequency response, large oil flow capacity, accurate fault diagnosis, mechanical zero adjustment of zero cover valve, high strength, displacement feedback of valve core position, optional valve core position stroke monitoring. |
 |
Parker D * 6FH series pilot operated proportional directional valveThe D * 6FH series pilot operated continuously adjustable directional valves with nominal sizes ranging from CETOP10 to CETOP25 (Parker's in-house standard) are used to control and regulate flow. This valve has integrated electronic components, and the valve core position of the main stage is adjustable. Compared to standard valves, integrated continuous differential circuits can provide higher flow rates. Typical applications include precise flow control and achievable flow regulation, with valve core position monitoring during fast/low-speed operation, such as press control, dynamic position adjustment, and pressure/flow closed-loop system regulation. |
