1. The Fundamental Design of Ball Valves: Dedicated to Isolation The core design of a Manual Ball Valve dictates its optimal use as an On/Off Isolation Valve—specifically for Fully Open and Fully Closed service. Its central component, the spherical ball, contains a bored port. When the valve is full...
In many industrial settings, especially in industries such as petroleum, chemicals, pharmaceuticals, and power generation, explosion-proof safety is crucial. Automatic butterfly valves, as essential components in fluid control systems, are widely used in these high-risk areas. In explosion-proof env...
In industrial automation control systems, both butterfly valves and ball valves are commonly used to control the flow of fluids. While they serve similar purposes, there are notable differences in their design, applications, and performance. This article provides an in-depth comparison of automatic ...
Multi-pump parallel systems are foundational to modern fluid dynamics across municipal water supply, industrial processing, HVAC, and large-scale utility operations. This configuration strategically leverages multiple pumps to achieve flexible flow regulation, robust redundancy, and optimized energy...
The Ball Check Valve is a uniquely structured, reliably performing fluid control component designed for unidirectional flow. It utilizes a spherical ball as the closure element (disc), relying on fluid pressure to lift the ball off the seat or allow it to return, thereby ensuring one-way flow. This ...
When discussing the performance and lifespan of automatic ball valves, installation orientation is a critical engineering factor that cannot be overlooked. Installation orientation generally involves two aspects: flow direction and the spatial position of the actuator. Based on flow direction, ball ...
