When using, you should choose normally open or normally closed.
Angle seat valve is widely used for frequent start in a short time. It can save space by keeping the flow rate. It has the characteristics of sensitive response and accurate action. It can be used with solenoid valve and pneumatic control can accurately control the flow of gas and liquid. It can meet the requirements of accurate temperature control and dripping liquid.
The damp heat sterilization cabinet uses angle seat valve to control the amount of steam and accurately control the temperature.
technical parameter:
The angle seat valve can save space by maintaining the flow rate. It adopts a guided angle seat valve operated by a single-acting pneumatic actuator with spring safety protection. When using, you should choose normally open or normally closed.
The product is made of stainless steel casting and polytetrafluoroethylene. It can be used in most gas, liquid, steam and corrosive occasions. It has a radiator to protect the actuator. To ensure that the valve has a long life.
Principle and technical parameters of angle seat valve:
Single and double acting
Single-acting (pneumatic head is usually a hole); working principle; according to the effect of spring return to open and close, it is divided into normally open type and normally closed type.
Double-acting (the pneumatic head is usually two holes); working principle: control its switch by air supply. (According to customer requirements, you can also choose double-acting plus spring reset, the control is more precise)
Installation and maintenance:
Must comply with applicable safety regulations
1. The pipeline must be clean and free of pollution.
2. Install as needed, but it is best to make the actuator face upwards. Pay attention to the flow.
3. Pay attention to aligning the connecting valve with the pipeline, and remove the actuator only when the user has special requirements.
4. Before opening or repairing the angle valve, cut off the fluid and control air source and reduce the pressure in the piping system.
Notice:
Features when choosing flow direction A:
1. When the flow direction is selected, the service life of the product can be increased.
2. When the working medium is liquid, select this flow direction to prevent hammer impact.
3. For products with a diameter of Φ15/Φ20/Φ25, the working pressure must be below 0.3MPa, otherwise double
Acting actuator.
For products with diameter Φ32/Φ40, the actuator must choose a double-acting Φ100 size.
For products with a diameter of Φ50, the actuator must choose a double-acting Φ125 size.
Features when selecting flow direction B:
When the working medium is steam or gas, when the flow direction is selected, the flow tightness of the product can be improved
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 affect the service life of the product.
In addition, when the working medium is liquid, it is not waterproof against hammer impact.
