Ball valve are the three different types of rotary valves used in industrial plants. They are widely used in fluid-handling systems for flow control. These types of rotary valves are suitable for corrosive applications. They are used in detergent, pharmaceutical, chemical, rubber, pulp and paper plants, water treatment systems, textile mills and food processing plants, In general, ball valves offer many advantages when contrasted with other valve types. They provide superior ease of operation and can maintain and regulate high volume, high pressure and high temperature flow. Most ball valves offer rugged construction providing for a long service life, and a comparably low cost. Additionally, the design of the regulating element allows the valve to function without the complications of side loads, typical of butterfly or globe valves, and the valve design permits inspection and repair of seats and seals without removing the valves?
| Product introduction: |
Characteristic of the products
Reversing ball valve of electronic Stone of stainless steel It is a ball valve in the X vertical passway, its characteristic is two passways of the spheroid in order to fix up Xly, four passway requirements distribute on the circumference section of the equator of spheroid , 90 o'clock along clockwise rotation on the spheroid , can make two adjoint passways realize two Liang is interflowed .
Features
Four-way direction changeable ball valve is a kind of ball valve with X-pattern vertical bore.It s fe ature is, the ball valve s two bores
are arranged to be X-pattern , and its four bores are connected to each other two of adjacent bores can be connected to each other.
This valve of series can dispose many kinds of drives
This ball valve can be equipped with several types of operation device.
Stone ball valve medium flows into the principle
As drawn, need not operating " LL " type Stone ball valve board the hands or carrying out device rotating 90 spheroid only ', can switch over the flow direction of two kinds of medium at the same time , convenient and fast, realize the multi-purpose result of a valve.
