Description

Stainless steel wafer butterfly valve is a kind of valve which is mainly used for controlling the flow of medium. It is mainly composed of body, disc and stem. The butterfly valve is named for its disc shape which looks like a butterfly wing. It has advanced design, compact structure, light weight, small size, and can be used for throttling and shut off. It is a kind of widely used valve. The stainless steel wafer butterfly valve is made of stainless steel, which has excellent corrosion resistance and is suitable for medium with higher requirements for the material of the valve body. The valve disc adopts a semi-circular structure, which is supported by a stem in the middle, and is driven by a worm gear mechanism to rotate around its own axis to open and close. The valve disc is equipped with rubber seal ring, which is sealed with the valve seat, thus realizing the function of opening and closing. The valve is suitable for various types of media, such as water, steam, oil and so on. It has the advantages of simple structure, small size, light weight, easy installation and maintenance. It is widely used in various industries such as petroleum, chemical industry, metallurgy, electric power, papermaking and so on.

 

Main Product Features of Butterfly Valves

• The design is novel, reasonable, unique structure, light weight and fast.
• Small operation moment, convenient operation and convenient maintenance.
• It can be installed in any position and convenient for maintenance.
• The sealing parts can be replaced, the sealing performance is reliable, and the two - way seal zero leakage.
• The sealing material is resistant to aging, corrosion resistance and long service life.
• The structure is simple, the universal  interchange is good and the price is low.
• Stem seal is not easy to deform to avoid the usual stem leakage.The overall support is good, stable and firm.
• Seat rubber consumption, expand the potential impact of small, easy to control the torque values within the scope of the appropriate USES two pieces type stem connection without pin, simple and compact structure, convenient in maintenance disassembly.
• The butterfly board has automatic alignment function, and the butterfly plate and seat small oversize fit. Phenolic back seat has the characteristics of non-shedding, tensile, leakproof and convenient replacement, Because seat airtight cover is integral to backrest, the seating deformation is reduced.
