Marine Valves by Pressure Rating
Halcyon Valve supplies marine valves for shipbuilding, offshore and industrial applications with various pressure ratings including JIS 5K, 10K, 16K, ANSI Class 150 and PN standards. We provide reliable valve solutions according to vessel requirements, classification standards and operating conditions.Valves are classified by nominal pressure into the following categories: low vacuum valves, medium vacuum valves, high vacuum valves, ultra-high vacuum valves, low-pressure valves, medium-pressure valves, high-pressure valves, and ultra-high-pressure valves.
Overview
Vacuum Valves (by Vacuum Level)
| Valve Classification | Pressure Range (Pa) |
|---|---|
| Low vacuum valves | 10⁵ to 10² Pa |
| Medium vacuum valves | 10² to 10⁻¹ Pa |
| High vacuum valves | 10⁻¹ to 10⁻⁵ Pa |
| Ultra-high vacuum valves | Below 10⁻⁵ Pa |
Pressure Valves (by Nominal Pressure)
| Valve Classification | Nominal Pressure (PN) |
|---|---|
| Low-pressure valves | PN ≤ 16 |
| Medium-pressure valves | PN 16 < PN ≤ 100 |
| High-pressure valves | PN 100 < PN ≤ 1000 |
| Ultra-high-pressure valves | PN > 1000 |
