Frequently Asked Questions

Q: What is the difference between standard and nonstandard valves?

A: Standard valves are designed and manufactured according to universal industry specifications (such as ANSI, DIN, or JIS). Nonstandard valves are custom-engineered to meet specific sizing, material, pressure, or operational requirements unique to a particular system layout.

Q: When should I choose a nonstandard custom valve?

A: Custom nonstandard valves are ideal when you encounter space limitations in piping configurations, require unique connection sizes, or need to handle extreme temperatures, high pressures, or highly corrosive media that standard off-the-shelf valves cannot accommodate.

Q: What materials can be used for custom valve manufacturing?

A: A wide range of industrial materials is available, including carbon steel, various grades of stainless steel (304, 316, 316L), duplex steel, super duplex steel, alloy steel, and special alloys such as Hastelloy or Monel, tailored to your application's medium.

Q: Do nonstandard valves undergo the same quality testing?

A: Yes, all custom and nonstandard valves undergo strict pressure, leakage, and shell testing in compliance with global testing standards to ensure structural integrity and safe operation before dispatch.

Q: How long does the customization process typically take?

A: The lead time for nonstandard valves depends on design complexity, raw material availability, and specific engineering validations. We optimize each stage of production to minimize delivery schedules while maintaining maximum quality.
