Frequently Asked Questions (FAQs): KANGFENG DN40 316L Angle Seat Valve

1. An angle seat valve has what is the greatest benefit of an angle seat valve over a typical solenoid valve?

Angle seat valves are suitable for high-cycle, high-flow, and high-temperature applications. They have a more robust piston actuator that enables them to withstand greater pressures and faster cycle times than most solenoid valves. They are significantly better suited for steam, heavy liquids, and high-switching applications.

2. Is the valve Normally Closed (NC) or Normally Open (NO)?

This KANGFENSION valve type is Normally Closed (NC). The valve will close without applied air pressure and the valve will open with applied air pressure. This is a standard failsafe feature.

3. Is the 316L Stainless Steel valve suited for steam service?

Yes, exactly. It is one of its primary applications. That it consists of 316L stainless steel body and PTFE seals merely means that it is highly resistant to corrosion and acceptable for continuous operation with saturated steam at temperatures of up to 180°C (356°F) and pressures of up to 10 bar.

4. What are the types of connection ports of this DN40 valve?

You will need to check the exact thread specification. This valve typically will have a DN40 (40mm) port, which is equivalent to 1-½ inch.- The exact thread will typically be BSPP (G thread) or NPT. Refer to product specs or product images on the listing to determine the exact thread type (e.g., G1-½\\" or NPT 1-½\\" ) before purchasing.

5. What pressure of air is required to operate this pneumatic valve?

Actuator air pressure must be 2 - 8 bar (29 - 116 PSI). The valve will work at its full capacity within those limits. Keep your factory air supply clean and dry in order to provide optimum performance and longest valve life.

6. What is the Cv (Flow Coefficient) rating for this valve?

Cv value is a critical indicator of efficiency of flow. Here, in this DN40 angle seat valve, Cv value is approximately [Insert Value, i.e., 15]. i.e., very good flow rate with very small pressure drop. Ref. to technical datasheet for actual value.

7. Is the valve suitable for use for food, beverage, or pharmaceutical applications?

Yes. The 316L (1.4404) sanitary stainless steel body is the common option for sanitary and corrosive application in such an industry since it is even more corrosion-resistant. The PTFE gaskets are also chemically compatible with most chemical and food media. For full sanitary requirements, you would need valves with specially polished surfaces and certificates (e.g., 3-A), which this common industrial valve might not necessarily possess.

8. Are there accessories with the valve?

Yes, the valve comes with a muffler (silencer) built into the exhaust port that significantly reduces operating noise, which is of utmost importance for industrial comfort and safety. Solenoid valves, limit switches, and quick-connect fittings are generally optional accessories that might be purchased separately.

9. How do I fix or service this valve if it doesn't function?

Among the advantages of angle seat valves is that they can be repaired. The seal cartridge (spring and PTFE seal) can be replaced easily in most situations without having to unbolt the valve from the pipeline. KANGFENG valves are easy to service and repair kits are usually available to purchase.

10. How long is your warranty on this product?

We trust the quality of our KANGFENG valves. Product is covered by a standard [Insert your warranty period, e.g., 12-month] manufacturer's warranty against defects in workmanship and materials for normal use. For full information and terms, visit our warranty policy page.
