Products Introduction

Hydraulicaly controlled slow-closing check butterfly valve is the most advanced pipeline control equipment in China and abord. It is mainly installed at the inlet of the turbine of the hydropower station and used as the inlet valve of the turbine;Replaces the function of check valves and gate valves. When working, the valve cooperates with the mainengine of the pipeline, according to the principle of the hydraulic transition process, through the preset opening and closing procedures the water hammer of the pipeline is effectively eliminated, the reliable cutoff of the pipeline is realized, and the safety of the pipeline system is protected.

 

Products Feature

Complete control functions and high degree of intelligence, which can be controlled locally or remotely.

Strong adjustability and good controllability, which can effectively eliminate water hammer.

High-quality sealing,small flow resistance coefficient.

Replace the functions of the electric gate valve and check valve at the outlet of the water pump, and the mechanical,electrical, and hydraulic systems are integrated as a whole, reducing floor space and infrastructure investment.
