SUPCON BN1101F Plastic Lined Butterfly Valve

BN1101F series plastic-lined butterfly valves have both the temperature resistance of hard liner and the sealing characteristics of soft liner. When the valve works, only the perfluorinated plastic valve seat and the fluorine-lined butterfly plate are in contact with the medium.

Product Description

Product Overview

BN1 series triple eccentric butterfly valve is a structure designed with three-dimensional eccentric principle, soft seal, soft and hard multi-level seal and full metal seal processing technology, so that the butterfly valve in operation work, reduce its torque force, to achieve the function of labor saving and energy saving. This series of butterfly valve not only can resist the severe working conditions of high temperature and pressure, but also has excellent sealing performance, hard seal valve seat sealing surface, overlay welding cobalt-based hard alloy, wear resistance, long service life.

Performance advantages

Unique structure, small torque

Small and light type, flexible operation, labor-saving and convenient

Reliable sealing, can meet the standards at all levels

Good flow characteristics and with adjustment function.

Adopting the principle of eccentricity, which makes the sealing surface nearly zero wear and extends the service life of the valve.

Wide application, can be used for water, steam, oil, air, gas and other media.

Temperature applicable range span, -40 ~ 570 ℃ are available in a suitable structure.

The use of corrosion-resistant and other working conditions of the pipeline.

And the pipeline connection has RF, RJ, FM and other flange type and clamping type and lug type.      

The flange distance conforms to GB/T 12221-2005 / ASME B16.10 or API609.ISO5752 standard.
