Advantages and features of Hawe balancing valves
High safety and load control capability
The bidirectional pressure control design can prevent load from accelerating out of control or oil column rupture, and is suitable for cranes, construction machinery and other scenarios.
With self-adjusting throttling function, it can dynamically adjust the return oil resistance according to load changes to maintain pressure balance (the set pressure is usually about 15% higher than the load pressure).
Precise adjustment and high energy saving
Support linear flow adjustment, achieve hydraulic balance of the pipe network by setting the flow, and effectively solve the problem of uneven heating and cooling in the heating/air conditioning system.
The working pressure is up to 420bar, with small pressure drop and high pressure shock resistance, suitable for complex hydraulic systems.
Diverse structures and adaptability
Provide a variety of installation structures such as pipe connection, plate connection, and screw plug-in to meet different hydraulic pipeline requirements.
The flow coverage range is wide (such as the LHK series supports 65-365L/min), and it is suitable for double-acting actuators (hydraulic cylinders, hydraulic motors).
Durability and maintenance convenience
The valve body is made of ductile iron or corrosion-resistant material with a long service life; some models are equipped with opening indicators and locking devices for easy commissioning and maintenance.
The modular design supports the rapid replacement of key components (such as seals and valve cores) to reduce downtime.
Precautions for use
Installation requirements
The matching model should be selected according to the system pressure to ensure that the nominal pressure is higher than the maximum pressure of the system; the installation direction should match the load direction to avoid reverse installation and functional failure.
It is recommended to install filters and manual valves before and after the valve to prevent impurities from clogging the valve body and facilitate fault maintenance.
Medium and environment adaptation
The cleanliness of the medium is high, and the pipeline needs to be cleaned regularly (the oil cleanliness level is recommended to be no less than ISO 4406 18/16/13).
High temperature or corrosive media require temperature-resistant sealing materials (such as fluororubber) or special coating valve bodies.
Operation and Maintenance
Avoid long-term overpressure operation (over 420 bar peak pressure), regularly check valve core wear and spring reset function, and stop the machine for replacement in case of abnormality.
During debugging, special intelligent instruments should be used to calibrate flow and pressure, and arbitrary adjustment is prohibited after locking the opening.
Selection Recommendation
For frequent start-stop scenarios, the sliding valve structure is preferred, and it is recommended to use a two-stage pressure valve in high-precision control scenarios.
For explosive environments, explosion-proof certified models should be selected, and the power supply voltage fluctuation should be ensured not to exceed ±10%.
Summary: The core advantages of Hawe balancing valves are high safety, precise adjustment and diversified adaptation, but they must strictly follow the installation specifications and medium requirements, and pay attention to regular maintenance and pressure matching.
