Floating ball valve and Trunnion ball valve

Ball Valves are a type of piping controller that shuts off or controls the flow in a pipeline by utilizing a hollow ball and round seats held at a valve body. There are two fundamental technologies for the layout of ball valves, floating ball design and trunnion mounted ball layout.  The Significant components of a ball valve would be:  The Bonnet …

High Performance of Sinov Cryogenic Ball Valve

Due to the rising demand of Liquid Natural Gas (LNG) nationally and internationally as well as the boost in Ultra High Purity cryo systems for the semiconductor marketplace, our cryogenic ball valves obtained much more orders this year. We collaborate with several renowned industrial gas manufacturers worldwide Sino Valve (SINOV) cryogenic ball valve has a three (3) pieces valve body degreases …

Trunnion Ball Valves Operating Dynamics Analysis

For a time, the idea has been around that a trunnion mounted ball valve could be opened under complete differential pressure if the piping system can withstand the forces as well as the increase in pressure. As dimensions and operating pressures grow, however, if that valve is opening with very little if any pressure downstream, several factors need to be …

The Most Important Things When Repair Ball Valve

Ball valves are process valves specified to be used in chemical plants, mining, and settings that are non-refinery. These valves are used in applications that require critical isolation, higher temperature, higher pressure, rust, erosion/abrasion and solids (slurry or differently). It’s these processes that drive the demand to get metal-seated valves that are quarter-turn. End users who choose ball valves need …

The History of Ball Valve Material

The Roman ball valves were made from a bronze alloy to the ASTM B62 bronze chemistry of today. These ball valves were used in plumbing systems in homes and buildings. The valves and technological discoveries of the Roman period could disappear under those dark ages’ cloak, and it was that valve materials became a topic of interest.  The 19th century …

What is DBB Valve: Double Isolation and Bleed Valves or Double Block and Bleed Valves(2)

In the previous article we talked about the introduction and definition of DBB valves, please see  What is DBB Valve: Double Isolation and Bleed Valves or Double Block and Bleed Valves(1) In this article we will continue with application of DBB valves. Application DIB and DBB valves are used in applications where crucial isolation is needed to make sure that leakage …

What is DBB Valve: Double Isolation and Bleed Valves or Double Block and Bleed Valves(1)

Introduction “Whenever a customer says they want DBB, most people may think it refer to monoflange double block and bleed valves, or integral type and modular type. But it is principally depending on the application and their previous experience with what they believe DBB valves to be,” states Wilia Wu, Technology Manager for Sino Valves. “Based on clients’ favorite valve …

What Is a Ball Valve

There are four basic body styles of ball valves: fully welded, three-piece body (also referred to as side or end-entry), split-body, and top-entry.  The distinction is based on the valve’s parts are manufactured and assembled, however, the valve operation is exactly the same in each kind.  Each design has its advantages.  By way of instance, the plan of this Sino …
