Crash Course to Valves – 3 Valve Mechanisms


Ever wondered what is the difference between Manual, Control and On-off Valves?

Valves are crucial components in regulating fluid flow in piping systems. They can be divided into three types: Manual Valve, Control Valve, and On-Off Valve.

Manual Valve can be operated manually, without additional accessories. It only functions to open or close the flow completely. This type of valve has advantages in terms of cost, so it is cost-effective. An example of this type of valve is the butterfly valve, which can be used from the JA Series.

Control Valves operate automatically and use the principle of changing pressure, flow, and temperature in the fluid flow. They consist of Valves, Actuators, and Positioners. This type of valve allows for flow adjustment according to specific needs, and one example of a valve suitable for this is the Ball Valve, such as the Neles – RA Series (Segment), M-1 (Ball Valve).

On-Off Valve is controlled automatically via a signal sent by an electric, hydraulic, or pneumatic actuator. This type of valve only functions to completely open or close the flow, but can be controlled automatically. An example of a valve suitable for use is the Butterfly valve with the L12 product, as well as the Knife Gate Valve- Stafsjo.

To select the appropriate valve type, it is necessary to consider the needs and conditions of the piping system. Consult with our experts for further guidance on valve selection and specific applications.
