Q: Which industry standards does this check valve comply with?

Our valves are designed and manufactured according to MSS SP-71, BS 5153, and EN 12334 standards, with flange dimensions matching ASME B16.1 and EN 1092.

Q: What materials are used to prevent corrosion in the valve?

We utilize Bronze for the disc and high-grade Stainless Steel for both the stem and the spring to ensure superior corrosion resistance in various environments.

Q: How is the valve tested before shipping?

Every unit undergoes strict test and inspection processes in accordance with API 598 to guarantee leak-proof performance and operational reliability.

Q: What is the maximum available size for these valves?

Our Control Check Valves are available in a wide range of sizes, extending up to 24 inches to accommodate large-scale industrial pipelines.

Q: Can these valves be used in high-temperature environments?

Yes, the use of Graphite packing and specialized alloy components allows these valves to maintain a seal under significant thermal conditions.

Q: What is the primary function of a check valve in a piping system?

A check valve allows fluid to flow in only one direction, automatically preventing reverse flow (backflow) which could damage pumps or contaminate the system.
