Top Entry Eccentric Half Ball Valve

Introduction

This series of butterfly valve adopts double eccentric soft sealing structure,suitable for food,medicine,chemical industry,
petroleum,electric power, textile, paper and other water supply and drainage, gas pipeline for regulating the flow and
interception of medium.

Features
1、Low pressure loss: The flow channel is completely unblocked when fully opened, and the water loss is zero.

2、Particle abrasion resistance: suitablefor fibers,tiny solid particles, pulp,etc.

3、Suitable for high-velocity media:straight-through flow channel,strong eccentric crankshaft makes it suitable for high-velocity
and vibration-free.

4、Long service life:no wearing parts,no friction between the sealing surfaces when the valve is opened and closed.

5、Convenient maintenance: Open the valve cover to perform maintenance without removing it from the pipeline.
