Hot-selling Motorized Butterfly Valve - PTFE lined butterfly valve – Nortech
Product Detail: What is PTFE lined butterfly valve ? PTFE lined butterfly valve is a valve used for flow regulation in large pipe diameters in which the disc takes the form of disk. Operation is similar to that of a ball valve. A plate or disc is positioned in the center of the pipe. The disc has a rod passing through it that is connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc... -

The disc is connected to an actuator or handle through the shaft,... -
Factory best selling Level Ball Valve - Trunnion mounted Ball Valve – Nortech
What’s Trunnion mounted ball valves? The ball valve is a form of quarter-turn valve which uses a hollow, perforated and fixed/supported ball to control flow through it. A trunnion mounted ball valve means that the ball is constrained by bearings and is only allowed to rotate, the majority of the hydraulic load is supported by the System constraints, resulting in low bearing pressure and no shaft fatigue. Advantages of trunnion ball design is the lower operating torque, ease of operation...
