Product Details

ZFV Ni-alloy steel wafer triple offset butterfly valve. The valve shown in photo is DN80, PN10. lever operator. The seat of triple offset butterfly valve is made of stainless steel sheet and graphite sheet laminated, this structure can effectively prevent the influence of tiny solids in the medium and the possible sealing surface occlusion caused by thermal expansion. So it will not cause leakage even if there is a small damage on seat.
