Cast Iron Butterfly Pneumatic Actuated Valve

Description

Pneumatic actuated center line butterfly valve is a type of valve that uses compressed air to open and close a disk-shaped valve in a fluid flow line. The valve is typically used to regulate the flow of liquids and gases. The valve is operated using an actuator, which is a pneumatically powered device that is activated by a controller. The controller can be mechanical or electronic, depending on the specific needs of the application. The valve can be opened and closed manually or automatically, depending on the requirements of the system. The center line butterfly valve is generally used in applications where a tight shutoff is required or when bi-directional flow needs to be regulated.

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.
