1. Equipped with a constant tension and pressure-stabilizing closed-loop oil circuit, the tension values remain stable during stretching, and the staged slow unloading structure prevents damage from component rebound.
2. Supports multi-channel synchronous stretching, with even force distribution across multiple steel strands, and an external easy pressure-adjustment setup so onsite staff can quickly tweak stretching parameters.
3. The valve body is designed to resist temperature differences, dust, and water, making it suitable for complex construction environments like open sites, rain, and dust.

Application:

Widely used in supporting hydraulic lifting platforms, forging presses, ship hydraulics, new energy, blow molding machines, and infrastructure prestressed tensioning equipment. The complete valve assemblies have undergone long-term continuous tension endurance testing, exhibiting excellent sealing and anti-clogging performance, as well as outstanding differential pressure resistance. The modular structure facilitates transportation and assembly/disassembly. Standard specifications are available for mass supply, while large-scale infrastructure projects can be customized with multi-link and multi-channel non-standard configurations, reducing procurement and maintenance costs associated with the simultaneous use of multiple tensioning devices.
