Product Description:
Rexroth superimposed check valve adopts a valve block superimposed design, which has the characteristics of space saving, high integration, and strong adaptability. It is widely used in hydraulic system control. The following are its core advantages and precautions for use:
Advantages and Features
Space Optimization
The superimposed structure can be directly installed on the valve block, reducing the number of pipe connection points, reducing the risk of leakage and simplifying maintenance. For example, the Z2S series can be directly integrated into the hydraulic valve group to save installation space.
High-pressure sealing performance
Some models (such as Z1S6-P133/V) support 31.5MPa high-pressure environment, and the cone valve structure ensures leak-free sealing, which is suitable for high-precision pressure maintenance scenarios.
Flexible Adaptation
Supports combined use with hydraulically controlled check valves, and controls the reverse opening of the valve core through external hydraulic signals to achieve two-way locking or slow pressure release. For example, Z1S6F05-4X/V can achieve dynamic adjustment through the control oil circuit.
Applicable in multiple scenarios
Machine tool hydraulic system : Control the feed and clamping action of the workbench to prevent reverse leakage of oil.
Construction machinery : Prevent the hydraulic cylinder from flowing backward due to gravity or impact to ensure equipment safety.
Injection molding machine : Maintain high pressure in the mold and optimize the injection speed and pressure curve.
Precautions for use
Control oil circuit connection
Make sure that the control oil circuit is correctly connected to avoid abnormal opening or closing of the valve core due to signal errors.
Regular maintenance
The valve core sealing and spring status need to be checked regularly to prevent leakage due to aging.
Selection basis
Selection needs to be based on the maximum system pressure (such as Z1S6 series supports 31.5MPa), diameter (such as Z1S6 diameter 6mm) and flow requirements.
