Electrical proportional valve

EPV Electrical Proportional Valves: With an accuracy of 0.5%, they outperform comparable products in the industry; featuring a self-developed high-speed micro‑valve, these valves boast a service life exceeding 100 million cycles; flow rates range from 60 to 3,000 L/min, and pressure can be adjusted in real time; pioneering the industry with proportional valves equipped with the MODBUS‑485 protocol, offering customers a variety of options. Widely deployed across numerous sectors, including lithium‑ion battery winding, laser cutting, and glass grinding.

ZK vacuum generator

It offers a variety of vacuum nozzle diameters and features built-in vacuum‑holding and pressure‑maintaining functions, with an operating pressure range of 0.25–0.7 MPa. Additionally, it supports multi‑plate integration, multi‑unit assembly, and flexible configuration options to suit diverse application requirements. It is widely used in industries such as 3C electronics, automation, photovoltaics, and semiconductors.

VT valve manifold

The only domestic manufacturer whose valve bodies are made of engineering plastics, featuring a simplified air‑path layout and a more robust structural design, allows for flexible combinations of various solenoid valves; it reduces labor and material costs, streamlines commissioning, and enables online monitoring and fault diagnosis. With a modular design, it supports IO‑Link, EtherCAT, and Profinet protocols. Currently, this product is primarily used in industries such as photovoltaics, lithium‑ion batteries, 3C electronics, and automation equipment.
