Butterfly Valve vs Butterfly Check Valve Although the butterfly valve and butterfly check valve have similar names and butterfly-like valve plates, they have different structures, working principles and functions. Structure of butterfly valve and butterfly check valve: Butterfly valve is a control valve, mainly composed of valve body, valve disc, valve stem and actuator. The…
What is Pneumatic Butterfly Valve? Pneumatic butterfly valve consists of two parts: pneumatic actuator and butterfly valve. A butterfly valve is a valve used to control the medium(liquids or gases), The main characteristics of butterfly valves are simple structure, small size, light weight, and rapid opening and closing movements. They are commonly used in piping…
Introduction: Gate valves are essential for various industrial, commercial, and residential applications. They control the flow of liquids by opening or closing a gate inside the valve. Over time, gate valves may experience wear and tear, leading to leaks or operational issues. Repairing a gate valve is a cost-effective way to extend its lifespan and…
Introduction: The function of butterfly valves is to regulate or segregate the flow of a system. In a pipeline system, we use the valve to repair, cleanse, or alter liquids when there is no flow through the pipeline. This is due to its capability of initiating, stopping, or prohibiting flow. Butterfly valves can be helpful…
