Frequently Asked Questions

Q: What is the main difference between SS and WCB body check valves?

The primary difference lies in material properties; Stainless Steel (SS) bodies offer far superior corrosion resistance and heat tolerance, making them suitable for steam and corrosive media, whereas WCB (Carbon Steel) is generally used for non-corrosive fluids.

Q: Can the ZHMSS-A1 handle high-pressure industrial steam?

Yes, the SS body is specifically designed for higher heat resistance and is highly recommended for installation in piping systems where steam or weakly corrosive media are present.

Q: Which international standards does this valve comply with?

The valve is manufactured according to globally recognized standards including API 6D, ASME B16.34, DIN 3202, BS 1868, and JIS B2071.

Q: How does a swing check valve prevent water hammer?

By acting as a non-return valve, it prevents the reverse flow of liquid. This stops the sudden collision of fluid against the valve seat, thereby eliminating the pressure shocks known as water hammer.

Q: What are the available size ranges for the flanged end version?

We supply a comprehensive range of sizes, typically spanning from 2" (50mm) up to 16" (400mm) to accommodate various pipeline diameters.

Q: Is this valve suitable for food and beverage processing?

Yes, due to the stainless steel construction which is rust-proof, clean, and corrosion-resistant, it is widely used in the food and beverage industry.
