The Regun DN15 Boiler Pressure Relief Valve is designed for HVAC technicians and homeowners looking to maintain system integrity by automatically venting excess pressure in water, oil, and gas heating circuits. Its primary benefit is providing reliable, automatic protection against over-pressurization, preventing costly structural damage to boilers or piping. While it offers excellent durability due to its high-quality brass construction, users must ensure the valve is professionally installed and regularly inspected to prevent scale buildup from affecting the pressure release mechanism.

This valve is designed for water, oil, and gas. Please consult a professional or the technical specifications before using it in a steam application.
While it depends on the system environment, it is good practice to inspect it annually and replace it if you observe persistent leaking or physical corrosion.
If you are not comfortable working with pressurized heating systems, it is highly recommended to hire a professional plumber to avoid leaks or system damage.
Yes, ensure the arrow on the valve body points away from the boiler and toward the discharge line.
The valve is constructed from high-quality brass to provide excellent corrosion resistance and heat tolerance.
Debris may be caught in the seat. Briefly trigger the manual release lever to flush the valve, or check if the system pressure is set too high.
The internal diaphragm may be stuck due to mineral buildup or corrosion. The unit should be replaced immediately as it is a critical safety component.
Tighten the connection using a wrench or re-apply thread sealant/Teflon tape if the seal was compromised during the initial installation.
For installation, ensure the system is depressurized before removing any existing valves. The DN15 features a threaded connection; use plumber's tape or appropriate pipe sealant to create a leak-free junction. Always install the valve in an upright orientation unless otherwise indicated by the flow arrow on the valve body. Compatibility is broad, covering standard heating loops using water, oil, or gas, but always verify the system's maximum pressure rating matches the valve's specification. For care, visually inspect the discharge port monthly for signs of weeping or corrosion. If the valve is located in an area with hard water, consider an annual flush or professional check to ensure mineral deposits have not impaired the mechanical movement of the internal diaphragm.
