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.

Stiefel, founded in 2013 and based in Guangzhou, China, specializes in high-performance gas solenoid valves for furnaces, critical components that control the flow of natural gas, propane, or butane to furnace burners, ensuring safe, efficient combustion and precise temperature regulation in residential, commercial, and industrial heating systems. A gas solenoid valve for furnaces acts as a safety shutoff, opening only when the furnace's control system signals ignition and closing immediately if the flame is lost or a fault is detected, preventing unburned gas from accumulating in the furnace chamber and reducing the risk of explosions or carbon monoxide poisoning. Stiefel's gas solenoid valve for furnaces is engineered with heat-resistant materials, including brass bodies, stainless steel stems, and high-temperature seals (rated to 180°C), ensuring durability in the hot environment of furnace enclosures, where temperatures can reach extreme levels during operation. The gas solenoid valve for furnaces features a fast response time (less than 30 milliseconds) to control signals, enabling rapid shutdown in emergency situations, while its tight sealing (leak rate less than 0.001 cubic feet per hour) ensures no gas escapes when closed, maintaining safety and efficiency. What sets this gas solenoid valve for furnaces apart is its compatibility with various furnace types, including forced-air furnaces, boiler furnaces, and industrial batch furnaces, supporting both single-stage and two-stage combustion systems that adjust heat output based on demand, improving energy efficiency. Gas solenoid valves for furnaces from Stiefel are available in sizes ranging from 1/4 inch (for residential furnaces) to 2 inches (for industrial models), with pressure ratings up to 10 psi, ensuring they can handle the gas flow rates required for furnaces of all capacities, from 50,000 BTU to 5 million BTU. Equipped with integrated pressure taps, the gas solenoid valve for furnaces allows for easy monitoring of inlet and outlet gas pressure, enabling technicians to diagnose issues like gas line restrictions or regulator malfunctions, reducing maintenance time. Rigorously tested for compatibility with furnace control systems, temperature resistance, and durability, these gas solenoid valves for furnaces meet industry standards such as ANSI Z21.29 and EN 161, ensuring compliance with global safety regulations for heating equipment. Backed by Stiefel's expertise in research and development, the gas solenoid valve for furnaces incorporates innovations such as corrosion-resistant coatings and vibration-resistant designs that enhance performance in dusty or high-vibration furnace environments, extending service life. With Stiefel's comprehensive service network, customers receive expert support for selecting, installing, and calibrating gas solenoid valves for furnaces, including guidance on matching valve size to furnace capacity and integrating with ignition systems for optimal performance. For furnace manufacturers and operators seeking reliable gas control, Stiefel's gas solenoid valve for furnaces is an indispensable component that delivers safety, efficiency, and peace of mind.

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
