When choosing the right type of valve for your industrial or other application, it is important to consider a number of factors that affect the valve’s performance, durability, and serviceability. This guide will help you navigate the complex world of valve selection and make an informed decision that meets your needs.

It all Starts with Planning

Choosing a valve always starts with careful planning. During the planning phase, it is important to determine the following factors:

Purpose of use: consider the purpose for which the valve will be used. What is the purpose of the valve? What are the flowing substances and their characteristics?

Operating conditions: what is the temperature and pressure at the point of use of the valve? Does the valve need to be resistant to corrosion or chemicals?

Flow requirements: determine the required flow rate and volume. Is the flow continuous or does it fluctuate?

Control needs: Does the valve need to be fully open or closed, or does it control the flow rate?

Maintenance Needs by Industry

Different industries have different requirements for valve maintainability. The paper and board industry, the process industry, and equipment manufacturers may require different solutions depending on operating conditions and maintenance intervals. Paper valves are designed to be fully dismountable and serviceable, which significantly extends their service life.

Paper and board industry: in these applications, valves must be able to withstand high temperatures and pressures. Maintenance can be challenging, so demountable valves such as Maper’s ball valves are an ideal choice.

Process industries: In this environment, chemical resistance and corrosion resistance are critical. Oxygen-resistant valves and sealing materials such as PTFE are recommended.

Equipment manufacturers: The need for precise control and reliability is important. Demountable and serviceable valves ensure long life and consistent performance.

Connection Heads: Weld end, Flange end, and Threaded end

The type of valve connection is a key factor in its selection. The choice depends on the installation environment, operating requirements, and maintenance needs.

Weld head: the weld head is the ideal choice for permanent installations where high durability and reliability are required. Welding heads are particularly suitable for high-pressure and high-temperature applications. They are also good where leakage risks need to be minimized.

Flange head: flange heads are common for large valves where a strong and durable connection is required. They are easy to install and remove, making maintenance and replacement quick and efficient. Flange heads are widely used in industry, especially where valves need to be replaced or serviced frequently.

Threaded head: Common on smaller valves and are well-suited for domestic use or lighter industrial applications. They are easy to install and remove, making them convenient for applications where quick installation and removal is required.


Choosing the right valve is a multi-step process that begins with careful planning and continues with an assessment of operating conditions and serviceability needs. Choosing the right connection heads ensures the valves will work reliably and efficiently in your application.
