Frequently Asked Questions
Q1: What is the typical application of this valve?
This valve is designed for marine steam systems, such as main steam lines, auxiliary boilers, steam heating systems, and process steam on ships and offshore platforms.
Q2: Can the valve be used for other fluids besides steam?
While primarily for steam, it can also handle other non-corrosive gases and liquids within the temperature and pressure range. Consult our engineers for specific media compatibility.
Q3: What documentation is provided with the valve?
Every valve includes a Mill Test Report certifying material chemical and mechanical properties as per EN 10204 3.1. Additional certifications like NACE or PMI are available upon request.
Q4: What are the available flange standards?
The standard flanges are PN16 to PN64 (DIN/EN). Optional ANSI Class 150/300 flanges are available upon request. Please specify when ordering.
Q5: How do I select the correct size for my system?
Selection depends on steam flow rate, inlet pressure, desired outlet pressure, and pipe size. Our technical team can assist with sizing calculations based on your process parameters.
Q6: Is the valve suitable for high-temperature steam?
Yes, with appropriate material selection (e.g., WCB for up to 400°C, or alloy steel for higher temperatures). The standard cast steel version is suitable for most marine steam applications up to 400°C.
Q7: What is the expected service life?
With proper installation and maintenance, the valve can last 10–15 years or more in typical marine environments. Regular inspection of internal parts is recommended.
Q8: Do you provide after-sales support?
Yes, we offer technical support, spare parts, and repair services. Our team can also provide on-site troubleshooting guidance upon request.
