The stainless steel ball valve is a ball valve that realizes the unblocking or blocking of the valve by rotating the spool. It belongs to the same type as the plug valve, the difference is that the stainless steel ball valve is a closing part of the ball, which is a valve that can be opened and closed by rotating the ball around the center line of the valve body.
Product features of ball valve:
1. There are O-type ball valves and V-type ball valves.
Among them, the O-type adopts a floating structure, the ball core is a precision casting, and the surface is plated with hard chrome. The valve seat is made of reinforced polytetrafluoroethylene. No leakage, suitable for high viscosity, fibrous and granular media.
The V-type ball valve adopts a fixed structure, and there is a V-shaped cutout on the ball core, which can realize proportional adjustment, and the flow characteristic is approximately equal percentage.
2. The process is divided into pneumatic or electric.
Pneumatic ball valves must be equipped with a valve positioner if they want to achieve proportional adjustment; electric ball valves must be equipped with electronic electric actuators or servo amplifiers if they want to achieve proportional adjustment.
3. The material is divided into stainless steel ball valve, carbon steel ball valve, 304 ball valve, 316 ball valve and copper ball valve.
4. The application is divided into high pressure ball valve and low pressure ball valve.
High pressure ball valves are mainly used in petroleum, hydraulic oil, natural gas, construction machinery and other industries.
Low-pressure ball valves are mainly used in non-corrosive pipelines such as water.
