FAQ
Frequently Asked Questions
Selection requires a comprehensive assessment of operating conditions, fluid characteristics, and pressure requirements. You must determine the valve's function—whether for shut-off, regulation, or check (non-return) purposes—to match it with the most suitable type and material, ensuring it meets system needs.
If a leak is detected, immediately shut off the flow of the medium. Inspect the gaskets, seals, and check for any debris. Contact the manufacturer for repairs regarding seal issues; serious faults, such as valve body cracks, require replacement or professional after-sales handling.
Standard models are available from stock. Custom orders typically take 15 to 45 days, depending on complexity. For urgent orders, we recommend communicating in advance so the manufacturer can coordinate expedited production.
The selection is based on the corrosiveness of the medium and the temperature.For highly corrosive environments, 304 or 316 stainless steel is recommended; for conventional media such as water, oil, and gas, cast iron or carbon steel can be used, balancing cost and operating conditions.
Services cover selection guidance, installation and commissioning, and warranty repairs. Top-tier manufacturers provide rapid response times and on-site support to ensure stable production operations.
