Fisher globe valves are renowned in the industrial sector for their reliability, precision, and durability. As a supplier of Fisher globe valves, I am delighted to guide you through the various types available in the market. This comprehensive overview will help you understand the unique features, applications, and benefits of each type, enabling you to make an informed decision for your specific industrial needs. Fisher Globe Valve
1. Fisher Single – Port Globe Valves
Single – port globe valves are one of the most commonly used types in the Fisher product line. These valves have a straightforward design, consisting of a single plug that fits into a single port. The simplicity of their design makes them highly reliable and easy to maintain.
The operation of a single – port globe valve is based on the movement of the plug. When the valve stem is moved, the plug either closes or opens the port, controlling the flow of fluid. This design provides precise flow control, making it ideal for applications where accurate regulation is required.
One of the key advantages of Fisher single – port globe valves is their ability to handle a wide range of pressures and temperatures. They are suitable for both low – pressure and high – pressure systems, and can operate in extreme temperature environments. For example, in chemical processing plants, these valves can be used to control the flow of corrosive chemicals at high pressures and temperatures.
Another benefit is their excellent shut – off capabilities. The single – plug design allows for a tight seal when the valve is closed, preventing any leakage of the fluid. This is crucial in applications where safety and environmental protection are of utmost importance, such as in the oil and gas industry.
2. Fisher Double – Port Globe Valves
Double – port globe valves, as the name suggests, have two ports and two plugs. This design offers several advantages over single – port valves, especially in applications where high flow rates are required.
The dual – port arrangement allows for a larger flow area compared to single – port valves. As a result, double – port globe valves can handle higher flow rates with less pressure drop. This is particularly beneficial in large – scale industrial processes, such as power generation plants, where large volumes of steam or water need to be regulated.
In addition to high flow capacity, Fisher double – port globe valves also provide balanced forces on the plugs. When the fluid flows through the valve, the forces acting on the two plugs tend to cancel each other out, reducing the overall force required to operate the valve. This results in less wear and tear on the valve components, leading to a longer service life.
However, it should be noted that double – port globe valves may not provide the same level of shut – off as single – port valves. Due to the presence of two ports, achieving a completely tight seal can be more challenging. Therefore, they are typically used in applications where shut – off is not the primary concern, but rather flow control and high – capacity operation.
3. Fisher Cage – Guided Globe Valves
Cage – guided globe valves are a specialized type of Fisher globe valve that features a cage – like structure to guide the movement of the plug. The cage provides several important functions, including guiding the plug’s movement, reducing vibration, and improving stability.
One of the main advantages of cage – guided globe valves is their ability to handle high – pressure drops. The cage helps to distribute the pressure evenly around the plug, preventing cavitation and other flow – related problems. Cavitation can cause damage to the valve components and reduce the efficiency of the system, and Fisher cage – guided valves are designed to minimize this risk.
Another benefit is their precise flow control. The cage – guided design allows for a more accurate and predictable movement of the plug, resulting in better control over the flow rate. This makes them suitable for applications where precise regulation of fluid flow is essential, such as in the pharmaceutical and food industries.
Fisher cage – guided globe valves also offer good noise reduction properties. The cage helps to absorb the energy of the flowing fluid, reducing the noise generated by the valve. This is an important consideration in industrial environments where noise pollution needs to be minimized.
4. Fisher Split – Body Globe Valves
Split – body globe valves are designed with a body that is split into two parts. This design makes the valve easier to maintain and repair. When maintenance is required, the two parts of the body can be separated, providing easy access to the internal components of the valve.
The split – body design also allows for quick replacement of parts. In case of component failure, the damaged parts can be easily removed and replaced without having to disassemble the entire valve. This reduces downtime and maintenance costs, making split – body globe valves a cost – effective solution for many industrial applications.
Fisher split – body globe valves are available in various materials, including stainless steel, carbon steel, and alloy steel. This allows them to be used in a wide range of applications, from general industrial services to highly corrosive environments.
5. Fisher Angle Globe Valves
Angle globe valves have a unique design where the inlet and outlet ports are arranged at an angle, usually 90 degrees. This design makes them suitable for applications where space is limited or where a change in flow direction is required.
The angled design of Fisher angle globe valves offers several benefits. Firstly, it reduces the overall footprint of the valve, making it a good choice for installations where space is at a premium. Secondly, the change in flow direction can help to reduce turbulence and pressure drop in the system, improving the efficiency of the fluid flow.
Angle globe valves are commonly used in applications such as heating, ventilation, and air – conditioning (HVAC) systems, where they can be used to control the flow of water or refrigerant. They are also used in some industrial processes where a change in flow direction is necessary for the efficient operation of the system.
Applications of Fisher Globe Valves
Fisher globe valves find applications in a wide range of industries due to their versatility and reliability. Here are some common industries and the specific applications of these valves:
Oil and Gas Industry
In the oil and gas industry, Fisher globe valves are used for various purposes, such as controlling the flow of crude oil, natural gas, and refined products in pipelines, refineries, and offshore platforms. They are also used in well – head control systems to regulate the flow of fluids from the well.
Chemical Industry
Chemical processing plants rely on Fisher globe valves to control the flow of corrosive chemicals, acids, and bases. The valves’ ability to handle high pressures and temperatures, along with their excellent shut – off capabilities, makes them suitable for these demanding applications.
Power Generation Industry
Power plants, whether they are coal – fired, gas – fired, or nuclear, use Fisher globe valves to control the flow of steam, water, and other fluids. These valves play a crucial role in maintaining the efficiency and safety of the power generation process.
Water and Wastewater Treatment Industry
In water and wastewater treatment plants, Fisher globe valves are used to control the flow of water, chemicals, and sludge. They help in regulating the treatment process and ensuring the proper distribution of water.
