• Stainless steel or copper alloy valve body for strong corrosion resistance
• Adapts to oil-contaminated environments (NAS 9 hydraulic oil cleanliness recommended)
• Special valve core surface coating reduces wear and extends service life

• Complies with ISO 4401 standard interface for quick integration
• Reduces system installation costs
• Supports multiple signal inputs (±10V/4-20mA) and external logic control (PLC interface)

• IP65 protection level for harsh industrial environments
• Adaptable to high temperature (-30℃ to +120℃), dust, and humidity
• Built-in overcurrent protection and temperature alarm for fault diagnosis

The direction of the arrow on the valve body must be consistent with the flow direction of the medium. Vertical installation requires advance specification of customization requirements. Stay away from strong electromagnetic interference sources and ensure that the wiring is firm. It is recommended to install a manual gate valve at the front end for maintenance.

The working voltage must be controlled within the range of ±10% of the rated voltage to avoid impact damage caused by frequent switching on and off. Avoid using in high temperature, high humidity or dust-intensive environments, and regularly clean the surface oil and impurities of the equipment.

Before starting, it is necessary to power on several times for preheating, and the pipeline needs to be cleaned and a filter installed to prevent clogging by impurities. It is forbidden to disassemble the solenoid valve privately. When a fault occurs, it must be repaired by a professional. In an emergency, the implicit manual operation function can be used. Regularly check the aging of components, replace worn parts in a timely manner, and upgrade the software according to the specifications.
