2pc ball valve with groved connection.

The working principle of stainless steel pneumatic ball valve is to rotate the valve to unblock or block the valve. Pneumatic ball valve switch light, small size, can be made into a large diameter, reliable sealing, simple structure, convenient maintenance, sealing surface and the sphere is often in the closed state, not easy to be washed away by the medium, has been widely used in various industries.

Insulated ball valve is a kind of valve, general horizontal installation, it and flange gate valve is a type, the closing part is a ball, the ball around the center line of the valve body for rotation to achieve opening and closing. Ball valve in the pipeline is mainly used to cut off, distribution and change the direction of the flow of the medium.

The extended rod gate valve is one of the commonly used block valves, which is mainly used to put through or cut off the medium in the pipeline; Especially suitable for medium and large diameter pipe. The stem of the soft seal gate valve drives the stem of the gate to lift together. The transmission thread on the stem is outside the valve body. Therefore, the opening and closing and position of the gate can be determined intuitively according to the direction and position of the valve stem, and the transmission thread is easy to lubricated and free from fluid corrosion, but it requires a large installation space.
Features:
Valve stem lengthening, convenient for high position operation;
Smooth channel, flow coefficient is small;
Reliable sealing, light and flexible operation

Quick ball valve with internal and external polishing treatment, for food, medicine and other health conditions. There are two control modes: switch type and regulator type. Full diameter sanitary ball valve basically no flow resistance; Simple structure, small volume, light weight; Tight and reliable, it has two sealing surface, and the sealing surface material of the ball valve is widely used in various plastics, good sealing, can achieve complete sealing

1. Check valve refers to a valve whose opening and closing part is a round disc and acts to block the backflow of media by its own weight and medium pressure. It is an automatic valve, also known as check valve, check valve, return valve or isolation valve. The motion mode of valve disc is divided into lifting type and swing type. Lift check valves are similar in construction to globe valves, except that they lack a stem that drives the disc.
2, the medium from the inlet end (lower side) into, from the outlet end (upper side) out. The valve is opened when the inlet pressure is greater than the sum of disc weight and flow resistance. On the contrary, the valve is closed when the medium flows back.
3. Swing check valves have an oblique disc that rotates about the shaft and work in a similar way to lift check valves. The check valve is often used as the bottom valve of the pumping device to prevent the return of water. The combination of the stop valve and the stop valve can play the role of safety isolation. The disadvantage is that the resistance is large and the sealing is poor when closed.
