Trait and purpose
Hard Seal Butterfly Valve triple offset series are our company's leading products,
Which are used in such fields as metallurgy, light industry, electric power, petrochemistry,
Coal gas channel etc.
The Seal principle of hard Seal Butterfly Valve triple offset
The Triple Offset Butterfly Valve Provides a bi-directional bubbletight shut-off.
This geometry ensures that the disc seal contacts the body seat only at the final shut-off
Position without rubbing or galling, providing atorque generated resilient seal with sufficient
"wedging" to ensure auniform seal contact.

I:The machine apply the advanced micro electronic multi-function relay(PLC).that can be done based on the previous program,to connect and shut-off the electrical circuit.This program compose [ soft relay" to instead of the previous middle relay on drills machine.this control programs constitute by language software.to
achieve one by one single machine programs.that realize the simple of electrical circuit, decrease malfunction.easy to determine.and increase durable and certify reliable and the control accuracy.This multi-function relay (PLC) use on ordinary vertical drills that is a great innovation.to make this vertical drills upgrade distinguishing feature.and make a perfect products. The machine also add to
The foot-step switch and the hand-touched emergency stop switch to reinforce and protect worker safety.to strengthen the protection characteristic.allow this machine humanization.
