Xizheng

Xizheng is a Chinese manufacturer of hydraulic components supplying an extensive range of hydraulic directional valves, pressure relief valves, proportional valves, gear pumps, and hydraulic cylinders for industrial and mobile hydraulic systems. The company produces hydraulic components conforming to international standards ISO 4401 and CETOP for straightforward interchangeability with existing hydraulic systems. At Verkopershulp.nl, more than 718 Xizheng products are available for direct delivery.

Xizheng hydraulic valves are designed for operating pressures up to 350 bar and include 4/3-way and 4/2-way directional control valves, pressure relief valves, check valves, and flow control valves. Xizheng proportional directional valves provide continuous flow control for applications requiring precise speed and position regulation. All valves are manufactured with Cetop 3 and Cetop 5 mounting faces conforming to ISO 4401 for direct interchangeability.

Xizheng gear pumps are available in external and internal gear versions for operating pressures up to 250 bar with displacement volumes from 1.6 to 160 cm3 per revolution. These pumps are widely used as working pumps and pilot pumps in industrial hydraulic systems, hoisting installations, and mobile hydraulics. The robust construction guarantees long service life under continuous loading conditions.

Xizheng hydraulic cylinders are available as double-acting, single-acting spring return, and telescopic versions for operating pressures up to 200 bar. Connections conform to ISO 6020 and ISO 6022 for straightforward integration into existing hydraulic systems. Stroke length and bore diameter are available in standard DIN dimensions and custom specifications.

At Verkopershulp.nl, you will find the complete Xizheng range for direct ordering. Our hydraulics team advises on the correct valve selection, pump specification, and cylinder dimensioning based on your hydraulic circuit design and process parameters.

Frequently Asked Questions

What is the standard operating pressure for Xizheng hydraulic valves?
Xizheng directional valves and pressure relief valves are standard available for maximum operating pressures from 160 to 350 bar, depending on type and series. Proportional valves are available for operating pressures up to 315 bar. Specify your desired maximum operating pressure and nominal flow rate when ordering for the correct valve selection.
Are Xizheng valves interchangeable with Cetop valves from other manufacturers?
Yes, Xizheng directional valves are designed conforming to ISO 4401 Cetop 3 (NG6) and Cetop 5 (NG10) mounting faces. This means they are in most cases directly interchangeable with valves from Bosch Rexroth, Parker, Eaton Vickers, and other manufacturers following the same Cetop standard. Always verify the valve configuration (NC/NO and spool pattern) before mounting.
What flow rate can Xizheng gear pumps deliver?
Xizheng external gear pumps are available with displacement volumes from 1.6 to 160 cm3 per revolution for maximum operating pressures up to 250 bar. At a typical drive speed of 1450 rpm, these pumps deliver flow rates from 2.3 to 232 liters per minute. Select the correct displacement volume based on your desired flow rate and pump speed.
Are Xizheng hydraulic cylinders conforming to ISO standards?
Yes, Xizheng double-acting hydraulic cylinders are available conforming to ISO 6020-2 (medium duty) and ISO 6022 for bore and stroke standardization. This guarantees interchangeability with cylinders from other ISO-conforming manufacturers. Special stroke lengths and bore diameters are available on request.
What is the delivery time for Xizheng hydraulic components?
Common Xizheng valves and gear pumps in stock are shipped the same business day when ordered before 4:00 PM. Less common types or special configurations are typically available within 5-10 business days. Contact us for current stock status of your required component.
Are Xizheng proportional valves suitable for PLC control?
Yes, Xizheng proportional directional valves are equipped with analog inputs (0-10V DC or 4-20mA) or PWM inputs for direct control by PLCs and CNC controllers. Some models are available with integrated position controller (OBE) for precise valve positioning without an external controller.
What is the difference between internal and external Xizheng gear pumps?
External gear pumps are simpler in construction, lower cost, and suitable for mineral oil at pressures up to 250 bar. Internal gear pumps offer lower noise levels, higher efficiency at part load, and are suitable for higher viscosities and synthetic fluids. Choose based on noise requirements, efficiency requirements, and the properties of your hydraulic fluid.
Do you offer technical support for designing a hydraulic circuit with Xizheng components?
Yes, our hydraulics specialists assist in selecting and dimensioning the correct valve type, pump size, and cylinder specification for your hydraulic circuit. Send your circuit diagram or description of the desired machine function, and we will compile a complete component list using Xizheng components.
