How do ball valves work?

The Rising Stem Gate Valves and Non-Rising Stem Gate Valve

Understanding how a ball valve works is very simple. It is usually designed with a large drilled hole that runs from one side to the other through the center. The ball fits snugly into the base inside the pipe opening (port). It is attached directly to the valve's operating handle, which is usually located above or to the side of the device, usually on the outside of the piping assembly. By turning the handle, usually a quarter turn to 90 degrees, the ball rotates about its axis within the port.

 

This action aligns the hole in the sphere with the direction of flow of the media in the pipe, allowing it to pass freely through the ball valve. This is referred to as the open or open position. Turning the handle back 90 degrees in the other direction, closed or off, rotates the ball so that the hole through it is perpendicular to the direction of flow. At this point, the medium can no longer pass through the ball valve and the flow is completely blocked.

 

Application of ball valves

Ball valves are most commonly found in piping systems and related applications such as industrial cooling. Their role is usually to help manage the flow rate of liquid or gas through a specific port or opening, thus affecting the pressure balance in other critical parts of the system.

They are also a common feature in various types of faucets and taps, and are widely used in gas lines, household appliances and other industrial applications. In most cases, industrial ball valves tend to be more durable and sturdier in construction than their domestic counterparts. They are typically used in applications where machines or systems operate at significantly higher pressures and temperatures in manufacturing, assembly and production, plastics and metals, chemical, medical, industrial power, food and beverage, printing and textile, electronics, automotive, and logistics.

Types of Metal Seat Gate Valves

According to the sealing surface configuration, it can be divided into wedge gate valve and parallel gate valve. Wedge gate valve can be divided into: single gate, double gate and elastic gate; parallel gate valve can be divided into single gate Plate type and double gate type. Divided according to the thread position of the valve stem, it can be divided into two types: open stem gate valve and dark stem gate valve. 【 Resilient Seat Gate Valve 】 For industrial valves, the opening and closing parts of soft-sealed gate valves are gates. The movement direction of the gates is perpendicular to the direction of the fluid. The gate valves can only be fully opened and fully closed, and cannot be adjusted or throttled. [Principle of Resilient Seat] The resilient seat l gate valve is divided into two types: bright-stem resilient seat gate valve and dark-stem resilient seat gate valve. Usually there is a trapezoidal thread on the lifting rod, through the nut in the middle of the gate and the gui...

What is a knife gate valve?

Knife gate valves are designed primarily for on/off and isolation service in systems with high suspended solids content. Knife gate valves are particularly suitable for handling slurry, viscous, corrosive and abrasive media. These valves have minimal pressure drop in the fully open position, they are easy to start, they have a relatively low weight and are cost effective.   When are knife gate valves used? Knife gate valves are commonly used in mining , power plants and in the paper, chemical and food industries. Knife gate valves have the advantage of being very compact due to the linear movement of the closing flap (the plate that stops the flow of fluid in the closed position). The knife gate valve is primarily a globe valve, although it can also be used as a control valve when the flapper valve is in the partially open position. Knife gate valves can be used for fluids containing solid particles, such as waste water or sludge. Generally, knife gate valves are designed to seal o...

Midline (concentric) The structural characteristics of the midline Centerline (concentric) The structural feature of the centerline is that the shaft center of the valve stem , the center of the gate, and the center of the body are in the same position. The structure is simple and the manufacturing is convenient. Common rubber linings belong to this category. The disadvantage is that the gate and the valve seat are always in a state of squeezing and scratching, large resistance distance, and fast wear. In order to overcome squeezing, scratching, and to ensure the sealing performance, the valve seat is basically made of elastic materials such as rubber, but the sealing material is also limited by temperature in use, which is why people traditionally think that it is not resistant to high temperatures. Applicable to the pipelines of petroleum, chemical, food, medicine, paper, water and electricity, ships, water supply, drainage, smelting and energy, etc., and can be used in a variety of ...
