An angle seat valve is a valve used to control the flow of gases and liquids, widely applied in industries such as steam systems, water treatment, food and beverage, chemical and pharmaceutical industries, as well as in automation fields. Due to its quick opening and closing, precise operation, fast response, and ease of maintenance, it is popular in various applications.
The valve body is the main shell of the angle seat valve, designed to connect to the pipeline and support the internal components. Depending on the application, the valve body is typically made from materials like stainless steel, cast iron, and brass to withstand various working conditions.
2.Valve Core (Piston)
The valve core is the critical part that controls the flow of fluid. It is connected to the actuator and moves up and down to open and close the valve.
3.Sealing
Seals are used to ensure the valve is tight when closed and to prevent leakage of fluid. Common sealing materials include PTFE (polytetrafluoroethylene), EPDM (ethylene propylene diene monomer rubber), and Viton (fluororubber). EPDM has better heat and corrosion resistance but is more expensive and slightly less effective in sealing than other materials.
4.Actuator
Different types of angle seat valves use different types of actuators. Manual angle seat valves generally use a handwheel actuator. Automated angle seat valves use actuators similar to pneumatic cylinders, equipped with pistons, springs, and air ports, which can be connected to solenoid valves for precise automatic control. Electric angle seat valves are usually fitted with motors that convert electrical energy into torque to control the valve core.
Smooth Fluid Path
The 90-degree design of the valve body reduces resistance and turbulence during fluid flow. Compared to other valve types with the same nominal size, the angle seat valve offers higher flow rates and less pressure loss.
Excellent Sealing Performance
Angle seat valves have excellent sealing properties. The contact surfaces between the valve seat and core are precisely designed to prevent leaks effectively.
Wide Range of Applications
Thanks to their unique design and material choices, angle seat valves can be used in demanding environments. They can control various media such as steam, liquids, corrosive, and viscous fluids, and can work in high-temperature and high-pressure conditions.
Flexible Actuation Methods
Angle seat valves can be equipped with various types of actuators depending on the application:
◆ Pneumatic Actuators: Suitable for applications requiring fast opening and closing. They use air as the power source and can respond quickly, often used in automation systems.
◆ Electric Actuators: Ideal for situations where precise adjustment of the opening is needed. They allow for more accurate flow regulation.
◆ Manual Actuators: Suitable for systems that do not require automation, allowing for easy manual control on-site.
Compact Design, Space-Saving
The compact structure of angle seat valves is especially beneficial in environments where installation space is limited. The 90-degree layout of the valve and pipeline makes it easy to install the valve in confined spaces, making it suitable for automated systems with tight spatial constraints.
High Cost and Long Service Life
The specialized design and materials lead to a higher initial cost compared to other valve types. However, the long service life of the angle seat valve allows it to provide a return on investment over time.
For a single-acting pneumatic angle seat valve, the working process is as follows:
The angle seat valve is a unidirectional control valve; the fluid can only enter from one inlet and discharge from the other end.
◆ Opening: When the fluid enters the valve, an external solenoid valve sends a control signal, causing compressed air to enter the actuator. This forces the valve core to move upward, allowing the fluid to flow through.
◆ Closing: When the control signal is turned off, the compressed air exits the actuator, and a spring pushes the piston to return the valve core to the normally closed position, blocking the flow.
Food and Beverage Industry
In food processing, angle seat valves are commonly used in the transport of liquids such as milk, juice, syrup, etc. These valves are made from food-grade stainless steel and high-quality sealing materials to meet the hygiene standards required in the food industry.
Water Treatment Industry
In the water treatment industry, angle seat valves are used to manage different types of water flows and ensure water quality meets standards, such as in wastewater treatment and reclaimed water systems, while effectively controlling water flow and pressure.
Chemical Industry
Angle seat valves are often used to control the flow of corrosive chemicals, such as acids, alkalis, and other aggressive liquids. These valves are usually made from corrosion-resistant materials like stainless steel or PTFE to ensure long-term stability in extreme environments.
Pharmaceutical Industry
In pharmaceutical manufacturing, angle seat valves are used to precisely control the flow of liquid medicines, ensuring product quality and stable production processes. They are also used in cleaning and sterilization systems (CIP) to remove residuals and contaminants, ensuring hygiene standards are met.
Steam Systems
In high-temperature steam pipelines, the sealing performance of angle seat valves is critical to preventing steam leakage, ensuring efficient operation, and reducing safety risks. These valves are used in heat energy conversion, industrial heating, and steam generators to regulate the flow of steam.
Energy and Oil & Gas Industry
In the energy and oil & gas industries, angle seat valves are employed to control high-pressure, corrosive, and high-temperature fluid flows, playing an essential role in oil refining, natural gas transmission, and energy conversion.
