The angle seat valve maintains the flow rate and can save space. It uses a single-acting pneumatic actuator with spring safety protection to operate the guided angle seat valve. When used, you should choose normally open or normally closed.
Angle seat valves are widely used for frequent starts in a short time. They have the characteristics of sensitive response and accurate movement. When used with solenoid valves, they can accurately control the flow of gas and liquid with pneumatic control. It can achieve accurate temperature control, dripping liquid and other requirements.
The moist heat sterilization cabinet uses an angle seat valve to control the amount of steam and accurately control the temperature.
The principle and technical parameters of the angle seat valve
The angle seat valve maintains the flow rate and can save space. It uses a single-acting pneumatic actuator with spring safety protection to operate the guided angle seat valve .When in use, normally open or normally closed should be selected.
The product is made of stainless steel casting and polytetrafluoroethylene. It can be used in most gases, liquids, steam and corrosive occasions. It comes with a heat sink to protect the actuator. Ensure the valve has a long life.

The principle and technical parameters of the angle seat valve:
Single-acting and double-acting
Single-acting (the pneumatic head is usually a hole); working principle; reset according to spring To achieve the function of opening and closing, it is divided into normally open type and normally closed type.
Double-acting (the pneumatic head usually has two holes); working principle: air supply controls its switch. (According to customer requirements, you can also choose double action plus spring return for more accurate control)

6 Features
1. With valve open or closed position display.
2． External pneumatic pilot increases service life and is maintenance-free.
3． There is a self-adjusting sealing gland between the overflow port and the slider, which can improve the sealing performance.
4. The angle seat structure of the valve body can achieve large flow (especially compared with ordinary stop valves).
The structure is compact and the response is fast.
Applicable safety regulations must be followed
1. Pipes must be clean and free of contamination.
2． Install as needed, but preferably with the actuator facing upwards. Pay attention to the flow direction.
3． When connecting the valve, be sure to align it with the pipe, and remove the actuator only when the user has special requirements.
4. Shut off fluid and control air supplies and reduce pressure in the piping system before opening or servicing this angle valve.
Note:
Characteristics when selecting flow direction A:
1. When this flow direction is chosen, the service life of the product can be increased.
2． When the working medium is liquid, selecting this flow direction can prevent hammer impact.
3． For products with diameters of Φ15/Φ20/Φ25, the working pressure must be below 0.3MPa, otherwise double-acting actuators must be selected.
For products with a diameter of Φ32/Φ40, the actuator must be of double-acting Φ100 size.
For products with a diameter of Φ50, the actuator must be a double-acting Φ125 size.
Characteristics when selecting flow direction B:
When the working medium is steam or gas, selecting this flow direction can improve the flow sealing of the product
< p>Yes, but because the V-shaped sealing ring in the valve body is in contact with the working medium for a long time, it will have a certain impact on the service life of the product. In addition, when the working medium is liquid, it is not waterproof against hammer impact.
