Reliable Fluid Control Using Precision Engineering
Stiefel's solenoid valves are of the utmost accuracy, including a leakage rate of ≤0.001 cc/min and a lifespan of over 10 million cycles. Our valves are made of 316 stainless steel and PTFE with a salt water (up to 100 bar) high pressure and extreme temperature durability (-40°C to 300°C). This makes them useful for industrial fuel systems, steam lines, and chemical processing. For instance, a German pharmaceutical plant's sterilization system over 5 years used our double-block valves without any leakage. Our valves use dual-seal design which incorporates a secondary safety mechanism. The tungsten carbide seats maintain tight seals even in high viscosity fuel applications, like waste oil burners, due to their resistance to coking and abrasion.
