The globe valve plays a key role in maintaining stable pressure in hydraulic systems. It is an irreplaceable element of the installation, responsible for controlling the flow of fluids and ensuring optimal operation of the system. In what situations are globe valves used and where should they be installed?

Application of globe valves
Correct installation requires the use of appropriate, matching components. Important elements include valves that enable control of the flow between subsequent elements of the installation. Depending on the specificity of a given system, various variants are used, including: poppet valves, ball valves, globe valve , non-return valves, gas valves, angle valves, anti-contamination valves and many other types, and each of them performs a specific task in the system.
The poppet valve is a frequently used element. The simplicity of construction, solid workmanship and resistance to various substances make the scope of use extremely wide. One example is water installations with a characteristic structure. The design includes the following elements: pin, body, choke and handle that allows for flow regulation. The gland seals the body against the plug to protect the system from flooding and leaking. The ball is responsible for regulating the water flow.
Many currently available models use special filters to protect the ball against contamination, thus extending the life of ball valves. An example of the use of poppet valves are central heating installations, both in the case of a heat pump and a central heating boiler. When preparing appropriate safeguards, remember to properly locate individual system elements and safeguards. In water and heating installations, including gas, in single- and multi-family houses, as well as in industry - the poppet valve is a commonly used solution
Where is a globe valve useful in a hydraulic system?
Depending on the specificity of a given installation, poppet valves equipped with a traditional knob or lever are used, which seems to be an easier solution to use. In many situations, it also allows for a faster and more efficient response, but only if they are in the right places. In the event of a failure, a quick response is necessary to cut off the water supply to avoid additional losses. Depending on the model and application, they can be made of acid-resistant steel or carbon steel, the properties of which improve resistance and durability to various substances.
The ball valve is used in both open and closed water installations. In the first variant, a special hydraulic pump is responsible for maintaining the pressure, in the second - this role is performed by hydraulic elements. The use of poppet valves and their installation depends strictly on the type of installation. In open systems, the ball valve should be placed upstream or downstream of the pump so that a constant pressure can be maintained regardless of other factors, including operating power or engine load. In turn, the installation is closed with a system in which the use of a valve allows the system to be safe against overheating and too high pressure.
Globe valves at the Onninen wholesaler
At the Onninen wholesaler, we have a wide selection of globe valves, available in various variants. One of the simplest and basic models is the Valvex VIKING GW 1/2" cast iron globe valve, figure M83 , which looks like a tap. The prepared model is characterized by high durability, so it can be used even in difficult conditions. It is made of white malleable cast iron, thanks to which it is more resistant to cracking. According to the information provided by the manufacturer, the strength is increased by as much as 45%, and the tightness is increased by as much as 35%. assembly. The handle itself is also worth mentioning as it is resistant to UV radiation and temperature changes.
A special variant of the product is the Wolf globe valve with thermal protection 3/4" . This model is prepared for installation in a surface-mounted installation. Prepared by the Wolf brand. The whole is solid, durable and safe. The valve is additionally covered with a chrome layer.
Onninen's offer also includes the Honeywell Home 2 DR 1" globe valve KV = 8.6 . It is a characteristic solution, equipped with an electric drive with a rated power of 230V. A two-way model with a maximum working pressure of 8.6 bar. Body The valve is made of brass, making it durable and solid.
The EkoTech Presto 12 flow-through time valve is equipped with a special mechanism that allows automatic closing of the water outflow. This is an excellent way to save water, sewage and energy. An interesting feature is that the model is equipped with anti-theft protection, including heads that are resistant to strong impacts.
