Stiefel's Boiler Parts Benefits.

Complete Compatibility With Major Boiler Brands

We particularly specialize in the manufacture of parts for boilers, with 98% compatibility to the top brands like Riello, Honeywell, and Baltur. Our silicon carbide core ignition transformers which replace legacy components in industrial boilers, emit 35kV sparks at 1,200°C. A U.S. paper mill saw a 30% reduction in repair costs after using our OEM-quality flame sensors and fuel filters that were designed for easy integration into existing Riello burners. No matter if you are looking for parts for commercial condensing boilers or heavy duty industrial systems, our cross-reference guide will help you quickly identify and install the parts.

Stiefel, a trusted supplier of combustion equipment since 2013 with headquarters in Guangzhou, China, offers high-quality gas solenoid valves for boilers, specialized flow control components that regulate the flow of gaseous fuels (natural gas, propane, butane) to boiler burners, ensuring safe, efficient combustion and precise heat output control in industrial, commercial, and residential boiler systems. A gas solenoid valve for boiler acts as a critical safety device, opening to allow gas flow only when the boiler's control system confirms proper ignition conditions and closing immediately if the flame is lost or a fault is detected, preventing unburned gas accumulation and reducing the risk of explosions or carbon monoxide leaks. Stiefel's gas solenoid valve for boiler is engineered with durable materials, including brass or stainless steel bodies, nitrile rubber or fluorocarbon seals, and copper solenoid coils, ensuring resistance to corrosion, high temperatures (up to 120°C), and gas permeation, maintaining tight shutoff and reliable operation in boiler environments. The gas solenoid valve for boiler features fast response times (less than 50 milliseconds) to control signals, enabling rapid gas flow adjustment during boiler startup, shutdown, or load changes, which is essential for maintaining stable combustion and efficient heat output. What sets this gas solenoid valve for boiler apart is its compatibility with various boiler types, including fire-tube boilers, water-tube boilers, and condensing boilers, supporting both low-pressure (up to 10 psi) and high-pressure (up to 50 psi) gas systems, and integrating seamlessly with boiler control panels for automated operation. Gas solenoid valves for boilers from Stiefel are available in sizes ranging from 1/4 inch to 2 inches, with options for normally closed or normally open configurations, offering flexibility to match specific boiler designs and safety requirements, from small residential boilers to large industrial units. Equipped with manual override options, the gas solenoid valve for boiler allows for manual gas flow control during maintenance or power outages, ensuring operational flexibility and safety. Rigorously tested for leak tightness, pressure resistance, and coil performance, these gas solenoid valves for boilers meet international standards such as EN 161 and ASME, ensuring compliance with global safety regulations for boiler equipment. Backed by Stiefel's expertise in research and development, the gas solenoid valve for boiler incorporates innovations such as low-power consumption coils and enhanced magnetic circuits that improve efficiency and reduce heat generation, extending service life. With Stiefel's comprehensive service network, customers receive expert support for selecting, installing, and calibrating gas solenoid valves for boilers, including guidance on sizing, pressure compatibility, and integration with ignition systems to maximize boiler efficiency. For boiler manufacturers and operators seeking reliable gas control, Stiefel's gas solenoid valve for boiler is an indispensable component that delivers safety, efficiency, and peace of mind.

Frequently Asked Questions

Does Stiefel offer a service for specific models of boilers to manufacture individual parts?

Definitely. Our services include custom part development through CAD/CAM, and include custom CNC machining, laser welding, and rapid prototyping. For instance, we collaborated with the European boiler manufacturer to design a control module featuring integrated IoT sensors that considerably streamlined the product development time by 30%. No matter what your requirements are, be it modified non-standard boiler flanges or proprietary seals designed specifically for cryogenic applications, our engineers will work together to ensure that you get tailor-made solutions within six to eight weeks.

Hans M.
Dependable Parts for Outdated Boiler Systems

Stiefel’s boiler parts have really saved us a lot of stress with our 20 year old industrial boilers. The replacement ignition transformers and flame sensors are working perfectly and they even work with our old Honeywell controls. We are reducing unexpected shutdowns by more than 70% since switching and also thanks to same day servicing for urgent fuel filter parts.

Tailored Stiefel Solutions for Our Waste Boiler Project

Stiefel provided us with exceptional tungsten carbide nozzles along with valves that are resistant to corrosion. The abrasively charged particles and high temperatures of over two years have not replaced their parts. With Stiefel, satisfying tight deadlines was simple due to their speedy prototyping and material selection.

Advanced Material Engineering

Advanced Material Engineering

Some of Stiefel’s more distinctive work includes silicone carbide ignition transformers (working at resistances of 1,400°C) and PEEK-sealed valves which are shut off from chemically reactive fuel systems. These materials minimize the frequency of maintenance needs, as in a Mexican refinery where our parts lowered annual replacement expenditure by 45%, and increase the lifespan of parts.
Global Certification and Compliance

Global Certification and Compliance

Parts of our boilers have CE, ATEX, UL, and CSA certification as fitting for use in regulated markets globally. For example, our explosion proof solenoid Valves EEx d IIC T6 approved for Zone 1 hazardous areas are suitable for LPG powered boilers sold in the EU and North America.
Data Driven Predictive Maintenance

Data Driven Predictive Maintenance

Using our IoT-enabled parts like sensors placed in actuators and valves, clients obtain intel concerning their parts’ health in real time. A Dutch dairy plant’s use of this data to predict nozzle wear and replace them proactively led to a 35% reduction in unplanned downtimes and improved their maintenance budget.
