Enhanced boiler efficiency accrues with premium-quality components.
Stiefel’s boiler parts are unmatched when it comes to reliability and efficiency. Our solenoid valves made of 316 stainless steel and PTFE have a fuel containment leakage of ≤0.01 cc/min and a 10 million cycle lifespan which is essential for safe fuel control in high-pressure systems. For example, a German hospital’s boiler system upgraded to our double-block valves, which led to an annual leak reduction from 12 to zero. In a Swedish pellet plant, our biomass boiler tungsten carbide tipped nozzles get 5x the lifespan of standard nozzles, resulting in lowered maintenance downtime by 80%. To ensure compliance with ISO 17025, every part undergoes rigorous functional testing, which includes helium mass spectrometry and pressure cycling.
