Rexroth Proportional 4WRZE16W8-150-72 6EG24N9ETK31 F1D3M Blue -25°C To +70°C High Reliability Fast Response 350 Bar Cast Iron

Description:

4WRZE” means pilot operated proportional directional control valve, ‘16’ means specification, ‘W8’ is a symbol, ‘150’ means rated flow rate is 150L/min, ‘7’ in ‘72’ means component series, ‘2’ means specific model number, ‘2’ means specific model number. “The “7” in “72” represents the component series, and “2” represents the specific model number. 6E” means pilot control valve specification 6, with removable coil proportional solenoid, ‘G24’ means the power supply voltage is 24V DC, ‘N9’ means with hidden manual emergency operation, ‘ET’ means with hidden manual emergency operation, ‘G24’ means the power supply voltage is 24V DC, ‘N9’ means with hidden manual emergency operation. N9” means with concealed manual emergency operation, ‘ET’ stands for internal control of the oil supply and external control of the oil return, ‘K31’ means without connecting plug, with connector connecting plug according to DIN EN 175201-804, to be ordered separately, ” A1” stands for ±10V control value for the electronics interface, ‘D3’ for with pressure reducing valve ZDR 6 DP0-4X/40YM-W80 (non-adjustable), ‘M’ for NBR seals. The valve is a pilot-controlled four-way valve, actuated by a proportional solenoid valve. When the solenoid valve is not actuated, the main control spool is in the center position by means of a centering spring. When the solenoid valve is energized, e.g. by controlling magnet “b”, the control spool can be moved to the right, the control oil enters the pressure chamber through the pilot valve and deflects the main control spool proportionally to the electrical input signal, thus realizing the control of the direction and size of the volume flow. When the magnet is turned off, the control spool and main control spool return to the center position. The flow rate depends on the switching position from P to A and B to T or P to B and A to T (R). The valve is also available with an optional manual operating handle that allows the control spool to be moved without energizing the solenoid, but be aware that accidental triggering of the manual override may result in uncontrolled machine movement. In addition, due to the design principle, the valve is prone to internal leakage, which increases the service life.

Fields of application:

Industrial automation: used in various automation equipment, such as robotic arms, robots, etc., to realize precise position and speed control.
Engineering machinery: in excavators, loaders and other engineering machinery, used to control the movement of hydraulic cylinders and motors, to improve the flexibility and precision of operation.
Plastic machinery: in injection molding machines, extruders and other equipment, used to control the opening and closing of the mold and the flow of materials to ensure the stability of the production process and product quality.
Marine and offshore engineering: used in ship's rudders, anchors and other equipment to improve ship's maneuverability and safety.
Aerospace: In the hydraulic system of aircraft, it is used to control the movement of flight control surfaces to ensure the stability and safety of flight.

Advantages

High-precision control: driven by proportional solenoid, it can realize high-precision proportional control to ensure the stability and reliability of the hydraulic system.
Fast response: fast response speed, able to complete the adjustment of direction and flow in a short time, suitable for high-speed, high-precision hydraulic system.
High reliability: Bosch Rexroth's high-quality manufacturing process ensures the reliability and durability of the valve and reduces maintenance costs.
Multiple control modes: Supporting multiple control signals, such as analog and digital signals, it can be compatible with various control systems.
Strong adaptability: able to work in harsh environments, such as high temperature, high pressure, high humidity, etc., suitable for a variety of industrial and engineering applications.
