2.Product Description

As a gas modulation device & a two-way switch device, 600S gas low-load pneumatic butterfly valve is suitable to ventilation and dust removing pipeline in the industrial fields of metallurgy, mineral, cement, chemical-engineering, power generation, industrial furnace and so on.


3.The characteristics of the products

It completely solved the problem of complex debugging and make the technology simpler.

The debugging can be simplified from 5 steps to 1 step.

The debugging for electrical and mechanical position can be easy achieved through rotating the knob on the top of the dial after electric actuators and valves are assembled together.

Small opening force-torque, free-friction rotation, long service life

The seal performance for two-ways between the disc and the seat is superior  when the valve  closed.The friction between the disc and the seat is small. The operation is realized by the working principle that the shaft drives the disc to rotate 90° to realize flexible switch without jam, jumpiness.


More than 50,000 operation life without fault, keep your system operating safely and reliably.

Without connecting rod and bolts inside, the valve has reliable operation, long service life, which is easy to install in any direction, and not affected by the medium flow.


Simple structure, easy operation, high cost- effective.

The valve welded by the steel plate is simple& short structure, light weight, and is convenient to use and maintain, which is equipped with electronic whole actuatorto easily realize on-site operationand remotecontrol.


With a welded structure between central line disc and steel plate, the valve hascompact structure, light weight, convenient installation, small flow resistance, large flow capability, easy operation,and can avoid the influence of high temperature expansion.


Pneumatic ventilation butterfly valve is welded by steel plate with short size structure, light weight, convenient installation, small driving torque, flexible switch and convenient operation. Be equipped with seal ring, the body has small leakage because there is no visible interstices between the sealed parts. The large expansion interstices between disc and body can effectively avoid the blockade caused by expanding with heat and contracting with cold.
