Overview

Feature:

GB/T3036-94 Marine center line-type Butterfliy Valve is surplus sealing type, that is, inlaid rubber liner on the seat of the valve body. If the medium is highly corrosive, PTFE can be inlaid and lined with rubber on the back of PTFE to increase resilience.

The center type butterfly valve is limited in applicable pressure because of the overfilling mandatory sealing form, and is usually used under working conditions not greater than PN10. For the drain pipe is enough.
