Product introduction
The imported electric vacuum ball valve produced by Breer can be driven by electric, pneumatic or manual. The connection method can be flange quick-release, looper flange, welding, the structure can be straight-through, three-stage, and the seal can be used PTEF, fluorine rubber, PPL, pressure range PN16MPa-6.4MPa, nominal diameter is DN10-200mm, the material can choose 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 electric vacuum ball valve is suitable for connecting or cutting off the medium flow in the vacuum system. The valve uses a rotary electric, electronically regulated valve drive device, which can be switched by an external power supply (using a manual index switch or computer control) or External input signal to realize valve opening, closing or intermediate position control. The valve is straight-through and sealed by a spherical surface, so it can be used in both a vacuum state and a low pressure state. And can be installed in any position. Suitable working medium is acid or alkaline gas or liquid. Applicable medium temperature: Standard seals -25 ～ + 150 degrees High temperature-resistant seals -25 ～ + 230 degrees. Vacuum ball valves refer to ball valves whose working pressure is lower than the standard atmospheric pressure, forming a certain vacuum.

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 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.
