The wafer thin ball valve
Short name: The wafer ball valve Thin ball valve
Model: Q71F-16/40P
Overview of thin wafer ball valve:
The wafer thin ball valve of Q71F-16/40P is also called Italian ball valve. The flange is threaded. The product has the characteristics of short structure length, light weight, easy installation, etc. It is suitable for working conditions such as narrow space, difficult installation at high altitude, etc. The full bore design reduces the air resistance of the flow passage and facilitates flow control. The thin wafer ball valve can also provide a linear flow passage port and a V-shaped flow passage port.
Design features of thin ball valve:
1. ISO5211 platform connection
2. Anti fly out design of valve rod
3. Anti static device
4. Adjustable function of upper seal
5. Fire protection structure design
6. Shell dewaxing precision casting
Design standard of wafer ball valve:
1. Design and manufacture: DIN 3357
2. Flange connection: DIN EN1092-1
3. Wall thickness standard: ASME B16.34
4. Inspection and test: API 598
Thin the wafer ball valve is a new generation of short flange pitch ball valve developed by introducing foreign technology for domestic design. The shape of the ball core channel is rectangular, V-shaped and O-shaped. Wafer type ball valve uses stud bolts to connect the valve between two pipe flanges. It can be quickly opened and closed only by rotating 90 °. The operation is simple. The platform and handle are equipped with 90 ° switch with hole positioning piece, which can be locked as required to prevent misoperation. The valve can be widely used in petroleum, chemical industry, metallurgy, power station, light industry and other fields to cut off and control propylene, oil, water, gas and pulp or fibrous fluid.
