When it comes to valve types, there are gate valves, ball valves, needle valves and the like. While managing flow of the fluid in various industrial applications like oil and natural gas industry, ball valves are the most common option. These valves are known to be simple in their design, easy to operate, and capable of precise flow control. Handles are the important component of a ball valve, which can be used for opening, closing and throttling the valve when required. This guide will feature the various types of ball valve handles, their materials, installation, maintenance, and how to select the best one for your individual application.

What is a Ball Valve Handle?

A ball valve handle is the part of the valve that is manipulated by the user to adjust the fluid flow direction through the valve. It is tightly screwed onto the valve stem that is, in turn, connected to the ball inside the valve body. Through the handle rotation, the ball will either go with the flow path, and let the media pass through, or block the flow path, and stop the media flow.

Ball valve handles can be found in a multitude of designs, each of which is intended for a particular purpose and for user convenience. For example, handwheels, gear operators, and automatic actuators are some commonly used types. The choice of handle is determined by the valve size, the required torque and the frequency of valve operations.

Information on Common Ball Valve Handle Types

The ball valve handles have such design as to be able to meet the requirements of different industries and working conditions. Here, we will present different types which include lever handles, butterfly handles, push-button handles, T-handles, gear-operated handles, and electrical and pneumatic handles. There are different types of manufacturing systems. Each of them has its own structure, mode of operation, pros and cons and typical applications in different industries, making it important to understand the specific type of ball valve handles needed for optimal function and performance.

Lever Handles

Lever handles serve a simple design to operate since operators open or close the valve with a quarter-turn motion. This handle is convenient for rapid operation in both the industrial and residential areas. Its main advantage is that it is easy to use. However, in high-pressure situations, its effectiveness is limited by the force that needs to be applied manually.

Butterfly Handles

Butterfly handles, also known as flange handles, are circular in shape and have a valve stem that connects to the shafts that rotates at a 90° angle. This handle is a compact one and it needs less space than a lever handle so that it is suitable for small spaces. It provides process control but it might not be able to offer the fine control needed in some industrial applications.

Push-Button Handles

Push-button handles are made for quick and easy operation. These devices have a spring-loaded button that, when pressed, enables the ball to spin and direct the flow. These valve handles are widely used in pneumatic and hydraulic systems where quick on/off control is a necessity.

T-Handles

These T-handles have a T-shape that gives a comfortable grip and effortless operation. These are usually used in places where a broader gripping surface is required, for instance, in high-torque valves or valves that are located in hard-to-access areas.

Gear-Operated Handles

A manual gearing ball valve handle is a tool of operation. It is used for the control of large size valves or the valves under high pressure. Sometime these valves are difficult to operate even with the lever handle. The handle is complete with a gearbox. Thus, this transmission system provides a force multiplication, whereby the operator applies more force. Therefore, it is possible to turn the valve with less effort.

Electrical and Pneumatic Handles

In some industrial places, the automated control of ball valves is indispensable. This is where electric and pneumatic handles are used. These handles that are also called actuators permit remote control of the valve. They can be regulated by the signals from the process control system. Electrical and pneumatic handles allow for exact control of the valve. Consequently, they are suitable for applications that require either regular or complex valve operation. This handle type is often used in different applications including chemical processing and industrial settings.
