Commonly used types of manual valves

Manual valves are key control elements in the pipeline fluid transportation system, widely used in industrial fields, designed to ensure smooth fluid transportation and safe operation of the system. This article focuses on four common types: manual butterfly valve (simple structure, convenient operation, divided into handle type and worm gear type, applicable to different caliber pipeline), manual gate valve (commonly used in water distribution system, divided into open rod and concealed rod type, opening and closing status intuitive), manual ball valve (used to cut off the flow, shunt and adjust the direction of flow, opening and closing parts for the ball) and manual disconnecting valve (good abrasion resistance, maintenance is convenient, but opening and closing torque, nominal diameter). (≤200mm). Selection needs to be based on the pipeline characteristics and working environment to ensure that the system is efficient and stable.

Types of check valves and their application areas in detail

Check valves are key components to prevent backflow of fluids and ensure stable operation of industrial and civil fluid systems. The main types include swing-open (single, double, multi-valve) and lift-open (vertical, horizontal), which are suitable for different pipe sizes and flow rate scenarios. Materials such as cast iron, cast steel and stainless steel offer a wide range of options to meet corrosion, pressure and temperature requirements.
