VBN Electric Butterfly Valve

VBN series butterfly valve is a type of flow control device, used to make a fluid start or stop flowing through a section of pipe.

Application

VBN series butterfly valve is a type of flow control device, used to make a fluid start or stop flowing through a section of pipe. Stainless steel sanitary valves is well applied to stainless steel pipe systems for food,

beverage, dairy, brewing, pharmaceutical, biopharmaceutical and chemical industries.

Materials

Valve wet parts: SS304 or SS316L
Disc: SS304 or SS316L
Other steel parts: SS304 or SS316L
Seal: EPDM, Silicon or FPM
Finish: Semi-bright
Actuator: SS304

Standard Design

The actuator is made in three standard versions, normally closed (NC), normally open (NO) and air/air activated(A/A).
Manually handle locks the valve in 3 position: Full open, half open and closed.*
For different handles type, see Handle Available.
