當前位置：首頁 >> >>Butterfly Seriesoverview: long-life energy-saving type butterfly valve pneumatic butterfly valve is the development of the new company. Butterfly valve uses the design principle of three-dimensional eccentric, a new machining process of elastic sealing and hard and soft multi-level compatible with seals, butterfly valve in the operation of the seal is reliable, can achieve the sealing without leakage, the eccentric design and prolong the service life of the valve. Pneumatic actuator using the crank conversion structure, has the characteristics of large output torque, small volume, stable and reliable performance. With the valve positioner or solenoid valve supporting the use of proportional control can be achieved or switch control, suitable for gas, solid and liquid medium. Automation is widely used in papermaking, petrochemical, chemical, metallurgy, electric power, petroleum, light industry, environmental protection, building automation, industrial control system.
