As a professional manufacturer from Shanghai Zhibang Valve Manufacture Co., Ltd, we proudly present our Marine Steam System Check Valve with Metal Seat. Designed to withstand temperatures up to 400°F and available in sizes from DN25 to DN200, this flanged check valve is engineered for high-pressure steam applications in marine environments. Built with a heavy-duty metal seat, it ensures reliable backflow prevention under demanding conditions. Every valve is ISO 5208 pressure tested to guarantee leak-tight performance and long service life.
Key Features & Technical Specifications
- High Temperature Capability: Rated for steam up to 400°F (204°C), ideal for marine boiler and steam line systems.
- Metal Seat Design: Provides excellent wear resistance and sealing reliability in steam applications, minimizing the risk of seat distortion.
- Flanged Ends: Easy installation and maintenance with standard flange dimensions (ASME B16.5 or EN 1092-1, customizable upon request).
- Size Range: DN25 (1") to DN200 (8"), covering a wide variety of pipeline needs.
- ISO 5208 Pressure Tested: Each valve undergoes rigorous pressure testing (shell and seat test) to ensure zero leakage and structural integrity.
- Heavy Duty Construction: Robust body and disc materials (carbon steel, stainless steel, or ductile iron options) ensure longevity in harsh marine environments.
- Low Pressure Drop: Optimized flow path design reduces energy loss and maintains system efficiency.
- Applications: Suitable for main steam lines, auxiliary steam systems, condensate return, and deck steam services on ships and offshore platforms.

Frequently Asked Questions (FAQ)
-
Q: What is the maximum pressure rating for this check valve?
A: The standard design is Class 150 / PN16. Higher pressure ratings (Class 300 or PN40) are available as custom options. Please contact us with your required pressure. -
Q: Can this valve be used for superheated steam above 400°F?
A: For temperatures above 400°F, we recommend consulting our engineering team for material upgrades (e.g., high-alloy stainless steel or with thermal insulation). Standard metal seat design can handle temperatures up to 400°F continuously. -
Q: What flange standards are available?
A: We offer flanges according to ASME B16.5, EN 1092-1, JIS, or other standards upon request. The standard is ASME Class 150 RF. -
Q: How does the metal seat perform compared to soft seat in steam service?
A: Metal seat is preferred for high-temperature steam because it resists thermal degradation, offers better wear resistance, and maintains sealing integrity. Soft seats (elastomer) are not recommended above 250°F. -
Q: Do you provide a test certificate for each valve?
A: Yes, we provide a material test report (MTR) and a hydrostatic test certificate per ISO 5208. A factory acceptance test (FAT) can also be arranged. -
Q: What is the typical lead time?
A: For standard sizes (DN25-DN100), lead time is 15-25 working days. Larger sizes or special materials may require 30-40 days. We can expedite for urgent orders. -
Q: Can the valve be mounted in vertical pipeline?
A: Yes, this swing check valve can be installed in horizontal or vertical pipelines (flow direction upward). For vertical down flow, a spring-loaded check valve is recommended.
