Product Description

Product Specifications

Valve Type Eccentric butterfly valve Structure Eccentric
Standard EN/DIN/API Workmanship Investment casting
Sealing Direction Single-directional Sealing Grade Zero leakage
Temperature -20°C < T < 120°C Operation Hydraulic control

Characteristics

The cylinder controlled quick-closing butterfly valve is driven by a hydraulic cylinder with an eccentric disc structure, featuring rapid cut-off capability that can achieve second-level flow interruption in emergency conditions, effectively preventing medium backflow and leakage. The opening and closing speed as well as the buffer stroke can be flexibly adjusted according to the on-site pipeline anti-shock requirements, adapting to different working scenarios. Equipped with an energy storage device, the valve can automatically link to complete quick closing in case of power failure, pressure loss or system failure, providing safety guarantee for equipment and pipelines.
