Description
Probably the most popular type of ball valve is the Three-piece design. The 3-piece ball valve is ideal for almost any application where a straightforward on/off action is required. It can swiftly and easily open or shut off flow for the majority of liquids, oils, and gases. By varying the degree of partial opening or closure of the valve, the flow rate can also be managed. It is also known as a two-way ball valve because it permits bidirectional flow from the inlet to the outlet. This valves are used for high working pressure in Gas Application.
