A floating ball valves is a type of valves with disc, which is part of the valve that controls flow through them. The ball has a hole, or port, by the way, if the port is in line with the two ends of the valve occurs, the flow rate. When the valve is closed, the hole is blocked perpendicular to the ends of the valve and flow. The handle or lever may be in the position of the port for the position of the valve in line. The butterfly valve and ball are part of the family of rotary valves.
Ball valves are durable and usually work to get a perfect cut, even after years of stagnation. They are an excellent choice for applications detention.They do not provide precise control needed in applications that can control, but sometimes used for this purpose.
mounted ball valves are widely used in industry because they are very versatile, bearing pressure of 700 bar and temperatures up to 257 ° C. sizes typically range from 0.5 cm to 45 cm. They are easy to repair and operate.
There are five common body styles of ball valves: single body, in three parts, with the divided body, top entry, and soldiers. The difference is how the parts of the valve is based primarily on the cabinet containing the balloon, manufactured and assembled. The valve is the same in each case.
ball valves have a hole three-way L or T in the middle. Different combinations of flows are presented in Fig. It is easy to see that a T-valve, each pair of ports, or three to answer, but the position of 45 degrees, which could separate the three leaves no room for error. The valve can connect the port on each side of the port or separate the three, but can not connect all the lateral connections.
Butterfly Valves 4-way or more are also available commercially, the gateway is usually perpendicular to the plane of the branches. For special applications, such as driving compressed air motors from forward to reverse, turning the handle 4-way valve is simple. 4-way valve has two ports on the L-shaped balloon that does not connect, sometimes called an "X" connection.
