Valves

Valves in this category are pipeline components used primarily for shut-off and, in purpose-designed versions, for flow control. They are installed in water supply, heating and district heating systems as well as industrial and process pipelines. Their operating principle is based on the movement of a closure element relative to the valve seat. Selecting the correct product requires consideration of the service medium, body material, connection type and actual operating conditions.

Main types of valves

Depending on the pipeline connection, the range may include flanged and threaded valves. Flanged valves are commonly used in industrial and utility piping where a detachable connection is required. Threaded versions are intended for systems designed for this type of connection and are typically used where compact installation is appropriate.

Another important distinction concerns stem sealing. Traditional gland-packed valves use a packing assembly around the stem, while bellows-sealed valves employ a bellows element to isolate the stem area. The latter design is considered where enhanced stem sealing is an important requirement of the application.

Shut-off and regulating designs should also be distinguished. A shut-off valve is primarily selected for isolating the flow. Applications requiring continuous and accurate flow adjustment should use a valve specifically designed and specified for control service.

Valve materials and design options

Common body materials for this type of pipeline equipment include cast iron, steel and stainless steel. Cast iron valves are used in various utility, heating and general engineering systems when the specifications of the selected product match the operating conditions.

Steel valves are widely used in industrial piping applications. Stainless steel versions may be selected for process environments where corrosion resistance is an important material requirement. Body material alone, however, does not determine suitability; the complete valve specification must be checked against the service conditions.

Where valves are used

Industrial valves of this type can be installed in water supply and heating systems, boiler installations, pumping systems, utility networks, manufacturing facilities and process piping.

The suitability of a particular model depends on its design, sealing arrangement, component materials and the characteristics of the medium being handled. Products with similar dimensions or appearance should therefore not be treated as interchangeable without reviewing their technical specifications.

How to select the right valve

Start by defining whether the valve is required for isolation or flow regulation and identify the working medium. The next factors include operating pressure and temperature, body material, sealing design, installation arrangement and connection type.

Pipeline compatibility also requires checking the relevant DN and PN values, but these parameters alone are not sufficient for product selection. Two valves of the same nominal size can have different materials, designs and permitted operating conditions.

Valve price depends on body material, design, connection method, manufacturer and technical configuration. Before placing an order, compare the selected product specification with the requirements of the pipeline or project documentation.

FAQ

1. What is the difference between a globe-type valve and a gate valve?
They use different closure mechanisms and flow-path designs. The appropriate choice depends on the piping layout, operating duty and whether the primary requirement is isolation or another specific flow-control function.

2. When should a flanged valve be selected instead of a threaded valve?
A flanged valve is suitable where the pipeline incorporates matching flanges and a detachable industrial connection is required. Threaded valves are used on piping designed for threaded connections, so the existing or planned installation arrangement is a key selection factor.

3. What is the purpose of a bellows-sealed valve?
The bellows element provides a dedicated sealing barrier around the stem assembly. This design is considered for applications where enhanced stem sealing is required, subject to confirmation that the specific valve is compatible with the service medium and operating conditions.

4. Can a shut-off valve be used for continuous flow regulation?
A shut-off design is primarily intended for opening or isolating the flow. Where accurate and repeated throttling is required, a purpose-designed regulating or control valve is generally the more appropriate solution.

5. What information is required when ordering a valve?
Provide the service medium, pipeline parameters, operating pressure and temperature, required connection type and intended function. For replacement projects, existing valve markings or technical documentation can significantly improve selection accuracy.
