Product introduction
The imported pneumatic vacuum ball valve produced by Breer can be driven by pneumatic, electric, manual, and flanged quick-release, looper flange, and welded. The structure can be straight-through, three-stage, and sealed. Tetrafluoroethylene, fluorine rubber, PPL, pressure range PN16MPa-6.4MPa, nominal diameter is DN10-200mm, the material can be selected from carbon steel, 304,316, titanium alloy steel and so on. Because the valve is used in a very wide range, the same valve has different combinations in different situations and working conditions.
Product Details
The imported pneumatic vacuum ball valve uses a pneumatic actuator to drive the valve stem to turn 90o to achieve the switching purpose.It is to change the gas direction through the electromagnetic reversing valve, and control the execution cylinder to drive the ball valve, so as to switch on or off the medium in the vacuum (pressure) system pipe flow. Used in vacuum, dairy, wine, bioengineering, food, pharmaceutical, beverage, cosmetics and chemical fields. Optional feedback signal device and electric valve positioner.

1; flange connection This is the most commonly used connection form in the valve. According to the shape of the joint surface, it can be divided into the following types: smooth type: for vacuum ball valves with low pressure. Convenient processing: Concave-convex type: high working pressure, medium hard washer tongue-and-groove type can be used: washers with large plastic deformation can be used widely in corrosive media, and the sealing effect is better. Trapezoidal groove type: use oval metal ring as gasket, used for high vacuum ball valve with working pressure ≥64 kg / cm2, or high temperature high vacuum ball valve. Lens type: The gasket is lens shaped and made of metal. For high pressure high vacuum ball valves with a working pressure of ≥100 kg / cm2, or high temperature high vacuum ball valves. O-ring type: This is a newer form of flange connection. It is developed with the appearance of various rubber O-rings. It is more reliable in sealing effect than ordinary flat washers.
2: Threaded connection This is a simple connection method, often used for small valves. There are two cases: direct sealing: internal and external threads directly seal. In order to ensure that the connection is not leaking, it is often filled with lead oil, linen and Teflon raw material tape; among them, the Teflon raw material tape is widely used; this material has good corrosion resistance and excellent sealing effect. It is easy to use and store. It can be removed completely when disassembling, because it is a non-adhesive film, which is far superior to lead oil and linen. Indirect sealing: The tightening force of the thread is transmitted to the gasket between the two planes, so that the gasket plays a sealing role.
