Zhejiang stainless steel angle seat valve

Zhejiang stainless steel angle seat valveApplication scope:

Widely used in various fields such as chemical, petrochemical, petroleum, papermaking, mining, electricity, liquefied gas, food, pharmaceuticals, water supply and drainage, municipal, mechanical equipment supporting, electronics industry, urban construction, etc.

Zhejiang stainless steel angle seat valveFeatures:

1. Has valve open or closed position display.
2. External pneumatic pilot can increase service life and is maintenance free.
3. There is a self-adjusting sealing cover between the overflow port and the slider, which can improve the sealing performance.
4. The valve body corner seat structure can achieve high flow (especially compared with ordinary globe valves), with a compact structure and fast response. The angle seat valve can maintain flow rate and save space It adopts a single acting pneumatic actuator with spring safety protection to operate the guide angle seat valve When using, one should choose between normally open or normally closed Angle seat valves are widely used for short-term frequent starting, with the characteristics of sensitive response and accurate action. When used in conjunction with solenoid valves, pneumatic control can accurately control gas and liquid flow rates. It can meet the requirements of accurate temperature control and liquid dripping. The wet heat sterilization cabinet should use angle seat valves to control steam volume and temperature accurately.

Zhejiang stainless steel angle seat valveInstallation and maintenance:

Must comply with applicable safety regulations
1. The pipeline must be clean and free from pollution.
2. Install as needed, but with the actuator facing upwards. Pay attention to the flow direction.
3. When connecting the valve, pay attention to aligning it with the pipeline, and only remove the actuator when the user has special requirements.
Before opening or repairing the angle valve, cut off the fluid and control gas source, and reduce the pressure in the pipeline system.
Note:
Characteristics when choosing flow direction A:
When selecting this flow direction, it can improve the service life of the product.
When the working medium is liquid, selecting this flow direction can prevent water hammer impact.
3. For products with diameters of Φ 15/Φ 20/Φ 25, the working pressure must be below 0.3MPa, otherwise double pressure must be selected
Action actuator.
For products with a diameter of Φ 32/Φ 40, the actuator must be selected with a double acting diameter of Φ 100.
For products with a diameter of Φ 50, the actuator must be selected with a double acting size of Φ 125.
Characteristics when choosing flow direction B:
When the working medium is steam or gas, choosing this flow direction can improve the flow sealing performance of the product. However, due to the long-term contact of the V-shaped sealing ring in the valve body with the working medium, it has a certain impact on the product's service life. In addition, when the working medium is liquid, it is not protected from water hammer impact.
