8-Channel Relay Controller Modbus RTU/TCP over Ethernet/PoE (Waveshare Model B)

Product Introduction

The DN15 (G1/2″) brass safety valve is a critical protective device for pressurized systems such as air compressors, boilers, and solar water heaters. Manufactured from high-quality H59-1 brass, it ensures durability and excellent heat resistance in industrial environments.

Key Features

• Premium Material: The valve body is cast from H59-1 brass, offering corrosion resistance and the ability to withstand continuous working pressure.
• Smart Design: Features an integrated side port (female thread), allowing users to install an additional pressure gauge for easy operation monitoring (Note: The standard product typically does not include a pressure gauge).
• Automatic Mechanism: When pressure exceeds the set threshold (8 Bar), the valve automatically opens to release excess air/water, ensuring absolute safety for the system and users.
• Standard Size: Common 21mm (1/2 inch) connection thread for easy installation and replacement.

Practical Applications

• Installation on piston and screw air compressors.
• Pressure tank systems, foam lance tanks.
• Industrial and residential steam boiler systems.
• Solar water heaters.
