3PC Internal Thread High Platform Ball Valve

Product Overview

The 3PC Internal Thread High Platform Ball Valve is a three-piece ball valve designed for compact piping systems where internal thread connections are required. The high platform design allows for easy actuation with gear operators, pneumatic or electric actuators, and facilitates maintenance without removing the valve from the pipeline.

This valve provides reliable on/off and throttling control, excellent sealing performance, and high pressure and temperature handling capability. Its three-piece body construction enables quick disassembly, maintenance, and inspection, making it ideal for high-pressure, high-temperature, and corrosive media applications.
