Shut-off valves: For safe operation of your machine or system
Shut-off valves have the task of blocking the volume flow of a medium with the "on-off function". For the safe operation of a machine or system, this must be guaranteed even after thousands of repetitions.
A shut-off valve often has to fulfil even more requirements, especially when it controls the flow of compressed air, (potable) water, oil, gases and other fluids. In pipe systems, shut-off valves distribute the media in a targeted manner or meter and merge them.
Areas of application for shut-off valves
Shut-off valves are used in numerous industrial sectors. The right choice ensures process reliability, minimised maintenance and a long service life.
Which shut-off valves are available?
The most important types of shut-off valves at a glance:
- Ball valve: Full bore, robust and durable, ideal for gaseous and liquid media
- Knife gate valve: For large nominal pipe diameters, slow switching behaviour
- Butterfly valve: Compact design, good compromise between price and performance
- Needle valve: Precise control of small flow rates
- Check valve: Prevents backflow, works automatically without actuator
- Sleeve valve: Inexpensive to purchase, mostly for simple applications
When choosing the right shut-off valve for your application, the flow rate, medium, pressure and material are among the most important parameters. Depending on the function and effect, one of these different shut-off valves is used.
Difference between shut-off valve and stopcock
The difference between a shut-off valve and a stopcock lies primarily in the design and application:
- Shut-off valve: is a generic term for all valves that shut off the flow. They can have different functional principles and designs.
- Stopcock: Used as a synonym for ball valve. It is characterised by a rotating ball or cone that releases or blocks the flow in a hole. A stopcock is therefore a special form of shut-off valve - easy to operate, robust and suitable for standard applications.
As far as the actuator is concerned, you can choose between electric, pneumatic or manual actuation. Peripheral devices such as control and pilot valves, solenoid coils, switch boxes, electric and pneumatic positioners, hoses and fittings are also available. The TRI-MATIC range has a modular structure. This enables customised solutions for your specific application.
FAQ
A shut-off valve, also known as a shut-off fitting, is a technical component in pipework systems that can completely interrupt or release the flow of a medium. It is used to distribute, meter or combine media in a targeted manner or to isolate individual system components, e.g. for maintenance purposes.
There are numerous types: Ball valves, flap valves, gate valves, needle valves and more. The selection depends on the medium, temperature, pressure range and hygienic requirements.
A shut-off valve is a special type of shut-off valve, usually in ball valve form. The term shut-off valve is more comprehensive and includes many other designs, such as flap or slide valves.
