Precision Control for Steam Systems in Industrial Applications
Product Features & Applications
Purpose:
The Y43H Series Steam Pressure Reducing Valve is engineered to regulate and stabilize high-temperature steam pressure, protecting downstream equipment from overpressure and ensuring efficient thermal energy transfer. Ideal for:
- Power Generation: Turbine bypass lines, boiler feedwater control, and steam distribution networks.
- Petrochemical Processing: Reactor heating, distillation columns, and heat exchanger systems.
- HVAC/Industrial Heating: Building heating loops, autoclave sterilization, and dryers.
- Specialized Applications: Geothermal plants, food processing sterilization, and pharmaceutical steam lines.
Key Advantages:
- High-Temperature Resilience: Designed for continuous operation up to 350°C (662°F) with corrosion-resistant materials.
- Noise Reduction: Advanced trim design minimizes cavitation and steam hammer effects.
- Robust Construction: Forged steel body and hardened trim components for long-term durability.
- Flexible Control: Available in direct-acting or pilot-operated configurations for precise pressure management.

Product Details
- Operational Principle:
- Direct-Acting Design: Spring force counteracts upstream steam pressure, adjusting the valve plug position via a high-temperature diaphragm.
- Pilot-Operated Option: External sensing line for remote pressure control in high-vibration environments.
- Advanced Features:
- Built-In Condensate Drain: Prevents water hammer and erosion in saturated steam lines.
- Adjustable Blowdown: Optimizes energy efficiency by minimizing steam waste.
- Bellows Seal: Isolates the valve stem from high-temperature steam (optional).
- Typical Applications:
- Combined Cycle Power Plants: Regulating steam from HRSGs to steam turbines.
- Oil Refineries: Controlling steam pressure for catalytic cracking processes.
- District Heating Networks: Maintaining constant pressure in underground steam distribution lines.
