The throttle valve is a reliable element used in installations. First of all, it is used to regulate the flow of the working medium. It is worth learning more about the effective models available at Onninen.

How does a throttle valve work?
The throttle-return valve is used in pneumatic systems to regulate the flow of the medium. It allows you to maintain the appropriate pressure. It should be noted that the method of operation here is very simple. It is based on the pressure difference. You need to know that when the pressure on one side of the valve is higher, the receiver flap opens and allows the medium to flow. However, when the pressure increases, the flap closes and blocks the flow. The media flows through valve channels and choke holes. The plug is then moved until the through hole is closed.
When the valve is energized in the opposite direction, the media will flow completely freely. Also pay attention to the knob that allows you to control it. You should also check the maximum flow of the medium. You can choose a needle valve, which is used in industry wherever precise flow control is required. Such valves can be used to control the flow of various liquids as well as gases not only in the opposite direction, but in both directions. When choosing throttle-return valves, you also need to remember the oil viscosity.
Where should the throttle valve be installed?
Properly installed throttle valve affects effective operation, but also reduces the risk of reverse flow. You need to know that you need to check the flow direction carefully, so make sure that the arrow on the valve indicates the correct direction. The throttle valve is most often installed directly behind the pump. It should be located before the shut-off valve. In some cases, throttle-return valves can be installed at the medium return point.
When it comes to vertical or horizontal installation, it depends largely on the structure. Thanks to it, you don't have to worry about damaging the pump. The use of the pressure difference on the throttling element allows the flow to be opened or closed, but this occurs only after the threshold pressure difference is exceeded. Remember that individual elements of the installation cannot press on the body. During installation, you also need to check whether the ground clearance has not been restricted.
The use of a throttle valve in pneumatics
Pneumatics is used on a wide scale. However, for pneumatic systems to function properly, not only the medium is needed, but also throttle valves. Thanks to them, the medium can flow freely in one direction. They are an integral part of the pneumatic system, which means that it is possible to install a throttle valve on the actuator.
Thanks to this solution, you can reduce costs and gain convenient regulation. The valve ensures free flow of compressed air in one direction. It also allows throttling in the opposite direction. The use of additional needle valves allows you to control the flow rate and ensure full precision of work. Needle valves in this case are used when the flow rate is low. The firing pin can be screwed in and out of the socket. This limits the size of the gap. It also makes the throttling take place in one direction.
Throttle valves are one of the most important elements in a compressed air installation. They regulate the speed of piston rod extension in pneumatic actuators. They can be placed on the body or on the cables, although it must be admitted that the first solution is better because there is no need to install connectors. You can also make settings more easily. Valves regulate the extension speed. If the flow is reduced to a minimum, their operation will be very slow. They also allow you to correct the actuator's operation. They are used on a large scale in production lines and machines.
Proper connection of the throttle valve
Connecting the throttle valve is very easy and does not involve high costs. This is due to the fact that the connections are standardized. We can use a combination of two types of connections here. For example, thanks to external threads, you can quickly and easily fit the valve to the connection in the body, while the plug-in connector enables the installation of cables when the hose is placed in the connector. Vertical, horizontal and indirect installation can be performed.
Throttle valves in the Onninen offer
Onninen's offer includes the HERZ-ZTB DN20 thermostatic throttle valve . It is used for domestic water with a circulation pump. There is no need to support it with additional energy. It should be noted that it is resistant to pressure changes. It has automatic hot water distribution. Of course, when installing on a circulation stack, the flow direction marked on the body must be observed.
The manufacturer used a strong valve cone that responds to an increase in temperature using a thermostatic element. Also noteworthy is the HERTZ-ZTB DN15 thermostatic throttle valve and temperature limiter . It is equipped with a temperature limiter. It is suitable for domestic water circulation installations. Also in this model, there is no need to support the device with external energy.
