Direct-Acting Steam Pressure Reducing Valve (PRV) with Dual Pressure Gauges

About this part

High-performance direct-acting steam pressure reducing valve (PRV) designed to step down high boiler header steam pressure to a constant, stable low process pressure. Features a heavy bronze/ductile iron body, internal stainless steel diaphragm/bellows sensing mechanism, top adjustment handwheel, and dual integrated pressure gauges for instantaneous upstream and downstream pressure monitoring.

Key features

• Self-contained, direct-acting design requiring no external air or electric power
• Includes upstream inlet and downstream outlet dial pressure gauges for real-time monitoring
• Stainless steel hardened valve plug, seat, and internal diaphragm for extended service life
• High flow turndown ratio with rapid response to downstream demand variations
• Top ergonomic handwheel for easy downstream setpoint calibration

Typical applications and wear

Process steamers, ironing/laundry presses, autoclaves, dye vats, and jacketed heating vessels. Wear is caused by wet steam wire drawing and diaphragm fatigue.

Compliance

Critical for process repeatability, textile fabric quality, and protecting low-pressure downstream machinery.
