Pnematic angle Seat Valve has become an ideal choice for many pneumatic control systems due to its fast response speed, large flow rate, and high temperature and pressure resistance due to its PTFE seal. Unlike traditional valve designs, An angle seat valve is operated by pneumatically actuated piston,can accurately control the flow rate of fluids.Seat valve primarily constructed with a stainless steel body,these kinds of valve are distinguished by their angled seat design.This design enhance fluid velocity and reduced pressure on the valve body, making them highly effective for use in high flow fluids.
Introduce
Angle seat valve also as known as pneumatic angle seat valve,has unique foot seat design distinguishes it from other pneumatic valves. The inclined installation surface inside the valve body and the valve seat sealing insert constitute the foot seat design. This design can achieve the maximum fluid path and minimize fluid pressure loss.
Features
The angle seat valve has multiple angle designs, including 30 degrees, 60 degrees, and even 90 degrees. But the most common angle is 45 degrees. The 45 degree angle design not only makes the angled channel smoother, reduces turbulence and pressure drop, but also reduces the occupied space, which is more conducive to equipment integration.
Operate
There are two operating modes for angle seat valves: manual or automatic. Manual operation requires operators to directly open and close valves through mechanical means such as handwheels and handles; Automatic refers to the use of actuators, including electric or pneumatic, to control the automatic opening or closing of valves, in situations where frequent valve operation or remote operation is required.
Regardless of manual or automatic method, the first step is to act on the piston and then drive the valve rod to open the valve.
Valve seat angle is the angle formed by the fluid flow channel and the piston rod,this design make it has fast response speed and large flow rate, Unlike globe control valves that have slower response times and focus more on adjusting accuracy.Valve seat angle is suitable for applications with fast switching and high-frequency operation.
Angle seat valve has a very high flow capacity, making it a ideal for high-flow liquid, gas, or steam transmission,Because it is usually typically tilted at an angle of 45° or more, allowing fluid to pass through without making sharp 90-degree turns as seen in traditional straight valve seat. This significantly reduces flow resistance and pressure loss, enabling a smoother flow path and increasing the Kv value. Additionally, this valve features a large bore design, which provides a greater effective flow area when the seat valve is open, allowing more medium to pass through quickly.The unique angle design reduces flow resistance, enabling higher flow rates at lower pressures.
Angle seat valve is typically equipped with high-performance sealing elements, ensuring reliable sealing even under extreme working conditions. This makes seat valve highly popular in applications where sealing performance is critical.
Angle seat valves can be configured with either an automated control system or manual operation.
The automated versions use electric or pneumatic actuators to achieve precise flow control, making them suitable for applications that require real-time flow adjustments.
To meet the demands of different working environments, angle seat valves are usually made of materials that are resistant to high temperatures and corrosion.
This enables them to work reliably over long periods in industries such as chemicals, food processing, and steam.

Pneumatic angle seat valve has fast response speed and large flow rate,the applicable industries are as follows:
Angle seat valves are often used for controlling the flow of liquids, particularly in high-flow systems that require precise flow regulation.
For example, they are commonly used in water treatment, pharmaceuticals, and food processing industries to ensure precise fluid flow and regulation.
In gas systems, angle seat valves are used for controlling gases such as compressed air and natural gas, thanks to their low-pressure loss and high-flow capacity.
These valves are essential in pneumatic control systems, gas transmission, and automated equipment.
Angle seat valves are widely used in steam systems, especially in steam boilers and steam heating systems.
Their high-temperature resistance and excellent sealing capabilities allow them to effectively control steam flow and pressure, ensuring system stability and safety.
When selecting an angle seat valve, several key factors should be considered to ensure optimal functionality and performance:
The type of medium being controlled, including liquid, gas, or steam, must be clarified first. Different media have different material requirements, especially regarding corrosion resistance and high-temperature resistance.
Choosing a valve suited for a specific medium can extend its service life and improve operational efficiency.
The flow capacity of an angle seat valve is closely related to its size. It is important to select the right model based on system flow requirements and working pressure.
For higher pressures, a high-pressure angle seat valve is recommended, while systems requiring larger flow rates may require larger valve sizes.
The choice between an automated or manual angle seat valve should be based on application needs. Automated valves allow for precise flow regulation through control systems, making them ideal for automated production lines and remote control applications. Manual valves are suitable for systems where frequent flow adjustments are not necessary.
Different operating environments require different valve body materials. For high-temperature, high-pressure, or corrosive media applications, materials such as stainless steel or alloys should be selected to ensure the angle seat valve performs reliably under harsh conditions.
The sealing performance of an angle seat valve is a critical factor influencing its efficiency and lifespan. Selecting the appropriate sealing material for the working environment ensures the valve will not leak over time, maintaining system efficiency.
Angle seat valve belongs to the type of angle seat valve driven by pneumatic actuator. The piston rod of the pneumatic actuator drives the valve stem under the action of compressed air, further controlling the contact or separation between the valve core and the valve seat, thereby achieving the opening and closing of the angle seat valve. In this way, it is possible to control the diagonal seat valve with a pneumatic driven actuator, including regulating the flow of fluid, gas, or steam.
Pneumatic angle seat valves are generally used in conjunction with single acting actuator structures, which can only be ventilated in one direction. The piston rod can only extend under the action of air pressure and cannot retract under the action of air pressure, requiring the use of a reset spring. Compared to double acting actuators, it has a simple structure, low cost, and easy maintenance
