Advantages of Stiefel's Boiler Parts

Superior Parts Designed for Improved Boiler Efficiency

Stiefel's Boiler Parts are manufactured with high-grade materials which ensures the maximum dependability and proficiency. The solenoid valves made with 316 stainless steel and PTFE guarantees no more than leakage of 0.01 cc/min and a life span of 10 million cycles which is important for safe fuel control in high-pressure systems. An example is the double block valves for a German hospital boiler system that upgraded from 12 annual leaks to zero with their new valves. The propane-fueled biomass boilers at the Swedish pellet plant experience 80% less maintenance downtime due to the tungsten carbide tipped biomass boiler nozzles that have 5x the lifespan of standard nozzles. Stiefel’s parts are manufactured using stringent processes that include thorough functional tests with helium mass spectrometry pressure cycle and other ISO 17025 standard tests.

These valves are created for the largest industrial furnaces and use piston-style actuators with rapid response times (under 80 ms) and seats made of tungsten carbide which is known for being highly wear resistant. In a German steel mill’s reheating furnace, our valves endured 1,200 °C Surrounding temperatures and fierce gas pressure bursts, reducing maintenance intervals from monthly to quarterly. With the addition of shock mounts, these valves can easily withstand harsh vibrations.

Frequently Asked Questions

Do Stiefel’s boiler parts fit both gas and oil boilers?

Certainly. Our products serve a wide range of fuel types. Gas boiler specific components include premix nozzles and FGR valves that guarantee low-NOx emission (≤30 mg/Nm³) combustion. Oil boilers come equipped with high-pressure (200 bar) pumps and viscosity controllers heavily optimizing fuel for atomization and thus increasing periphery. A Russian maritime boiler saw an 18% reduction in fuel consumption when shifting between gas and biodiesel due to the versatility our dual-fuel parts offer.

Cutting-Edge Sealing Technology Ensures No Leaks

Cutting-Edge Sealing Technology Ensures No Leaks

This guarantees that the valves will be leak free even at high pressures and will not be compromised over time. The enhanced safety does not compromise efficiency. However, leak-free operation improves overall system efficiency and reduces gas losses and potential hazards.
Space Efficiency with Compact Structural Design

Space Efficiency with Compact Structural Design

These valves have compact space saving design features. They can be placed in constricted areas where standard performance valves could not fit. This design feature is beneficial for small scale industrial equipment and residential gas devices where space is limited. Reduced physical dimensions also facilitates easier installation, lower mounting space requirements and greater flexibility for system configuration.
Integration is Easy with Various Connection Sizes

Integration is Easy with Various Connection Sizes

The diameters of our connection complete our gas solenoid valves. From small - diameter connections for household appliances to larger ones for industrial pipelines. The variety of gas valves readily integrates into numerous gas systems. If you are building, upgrading an existing system, you will find a valve with the right connection size, which makes installation smooth.
