Double Eccentric Motorised Butterfly Valve
The double eccentric butterfly valve also named high performance butterfly valve. And our double eccentric type butterfly valve have two types,one type is the sealing is on the disc,like EPDM,the other type is the seat is on the body,like the PTFE. Compared to the triple offset butterfly valve,double eccentric butterfly valve can’t bear high pressure,high temperature because of the material of the sealing,but the it is also more cost-effective.
