Products Introduction

This series of butterfly valve adopts double eccentric metal sealing structure,which is suitable for water supply and drainage,thermoelectric, gas pipeline,textile and papermaking flow regulation with temperature ≤ 225°C and pressure ≤ 5.0MPa.

 

Products Feature

Compact structure, light weight, easy to operate.

Bi-directional flow sealing with1.1xPN,installation is not limited by the medium flow direction, arbitrary installation.

Metal sealing ring can be selected according to different media.

Adjusting retaining ring fastened with A2-70 screws and extra dowel pins.

Self-lubricating shaft sleeve, low operating torque.

Streamlined disc design,reduces the flow resistance coefficient, making the fluid channel more stable. reducing pressure loss and reducing sensitivity for vavitation.

Truss type disc design, disc has higher strength, suitable for high pressure grades and large diameters.
