Y-Pattern Globe Valve – Class 150 & 300
Y-pattern globe valves with angled flow path design for reduced flow resistance and minimal pressure drop. Manufactured to BS 1873 / API 623. Available in carbon steel, stainless steel, and alloy steel. Sizes 1" to 12". Ideal for high-pressure and high-temperature services including main steam, boiler feed water, and process lines.
Quick Summary
Y-Pattern Globe Valve = Globe valve with stem/seat angled at ~45° to pipe axis. The angled flow path reduces pressure drop by 40–60% vs standard T-pattern globe valves. Excellent throttling with lower energy loss. Used in high-pressure steam, boiler feed, and petrochemical process lines.

Key Specifications
Export Ready: EN 10204 3.1 MTCs. Third-party inspection supported. Also available in WC6, WC9, C5, C12, LCB, LCC body materials.
Design Features: Y-Pattern vs T-Pattern
Y-Pattern Advantages
- 40–60% lower pressure drop than T-pattern
- Straighter flow path reduces turbulence
- Better for high-pressure services (Class 600+)
- Reduced erosion from flow impingement
- Self-draining when installed at angle
- Lower pumping energy costs
When to Use T-Pattern
- Vertical pipe runs (space constraints)
- Low-pressure services where ΔP is not critical
- Applications requiring vertical stem access
- Budget-sensitive projects (lower cost)
- Standard flow regulation duties

Frequently Asked Questions
What is a Y-pattern globe valve?
A Y-pattern globe valve has a stem and seat angled at approximately 45° to the pipe axis. This angled flow path reduces flow resistance and pressure drop by 40–60% compared to standard T-pattern globe valves, while retaining excellent throttling capability.
What is the advantage over T-pattern?
40–60% lower pressure drop, straighter flow path reducing turbulence, better for high-pressure services, reduced erosion, and self-draining capability when installed at angle.
What sizes and materials are available?
1" to 12" in Class 150 & 300. Body materials: WCB, WC6, WC9, C5, C12, LCB, LCC, CF8, CF8M. Flanged (ASME B16.5) and butt-weld (ASME B16.25) ends.
