Butterfly check valve is a professional technological achievement of ivalve in the field of cutting-edge valves.

This valve is designed for the water industry, taking into account the best available dual offset technology and complying with the requirements of EN593 (BS 5155&DIN 3354) and AWWA C504. This is a well proven design used in thousands of devices around the world. these years,

ivalve has undergone continuous improvement and refinement, thus possessing unique features and benefits that are favored by both engineers and users.

The disk has a streamlined design to reduce head loss. There are a wide range of materials to choose from; Internal hard rubber lining also used for saltwater applications. The size and pressure can reach DN3000 and PN25 standards.

Equipped with hydraulic dampers as an option. It is easy to replace the valve disc seal on site without disassembling the valve from the pipeline.

When configuring dampers, reduce the eccentricity to protect the valve and shaft. Usually, powder epoxy coatings with drinking water certificates are used.

Quality first: honest materials, advanced production technology,

First class testing equipment and strict quality control ensure years of trouble free performance.
