Ball Valves: Design Standards and PerformanceStructure and FunctionBall valves are quarter-turn valves that use a spherical ball to control the flow of fluids. The ball has a hole through the middle, and when the valve is open, the hole aligns with the pipeline, allowing fluid to pass through. When
I. Analysis of the Causes of Excessive Switching Torque of Ball Valves<br /> (A) Problems with the Valve Body Structure<br /> • Unreasonable Sealing Structure: Insufficient machining accuracy of the sealing surface or improper selection of sealing materials will lead to an increase in the friction between the ball and the valve seat, thereby increasing the switching torque.
Valves are indispensable components in fluid transportation systems, and their main functions are to control the flow direction, pressure and flow rate of fluids. However, valves will generate certain flow resistance during the working process, which will not only reduce the flow rate of the system but also increase energy consumption. Therefore, optimizing the flow resistance coefficient of valves and improving their flow capacity have important practical significance.
Gate Valves: Design Standards and Industry NormsStructure and FunctionGate valves are linear motion valves that use a gate or wedge to control the flow of fluids. The gate moves perpendicular to the flow direction, allowing for precise control and reliable sealing. When fully open, the gate is retra
In steam systems, the selection of valves is crucial for the safe and efficient operation of the systems. The BS 1873 standard provides important technical guidance for the design and operation of steam systems.

The TRUNNION BALL VALVE API 6D relief device and the GATE VALVE quick closing design are two common emergency shutdown solutions. This article will compare these two designs from multiple dimensions to help you better choose a suitable emergency shutdown system.<br />
Understanding Butterfly Valves in Water Treatment SystemsStructure and FunctionButterfly valves are quarter-turn valves that use a flat disc mounted on a rotating stem to control the flow of fluids. The disc rotates to open or close the valve, and it remains in the flow path even when the valve is f
Understanding Trunnion-Mounted Ball ValvesStructure and FunctionTrunnion-mounted ball valves are a type of ball valve designed with a fixed ball supported by a trunnion, which enhances stability and reduces operational torque. This design allows for precise control and reliable sealing, making them
In industrial fluid control systems, the choice of valves has a crucial impact on the stability and cost-effectiveness of the system.
