Side setting radiating fin can further improving radiating effect, promoted butterfly valve high temperature resistant endurance.
2, by being provided with tantalum carbide hafnium alloy layer and antifriction metal (AFM) layer, the high temperature resistant of tantalum carbide hafnium alloy in valve interior wall
Performance is high, can further poppet body high temperature resistance, by using antifriction metal (AFM) layer can be with poppet body inside
Wear-resisting property, the service life of poppet body, the dual-seal circle being made by polytetrafluoroethylene PTFE are closeer than general
Seal high temperature resistance is higher, while sealing performance is also more preferable.
3, by the protective cover being arranged outside driving motor, driving motor can be effectively protected not by ambient pressure
Damage, promotes the service life of driving motor, at the same the cooling fan of driving motor side setting can be by driving motor work
As when the heat that generates sufficiently radiate, promote the working efficiency and service life of butterfly valve.
