Safety Relief Valve FLAMCO 27110 3/4" x 1" threaded connection, 6 bar set pressure

FLAMCO safety relief valve model 27110 with 3/4" x 1" threaded connection and a fixed 6 bar set pressure is a compact pressure protection device intended for closed water-based heating and boiler systems. It opens automatically when system pressure exceeds the set point to release excess pressure and protect piping, vessels and components. The valve is designed for straightforward installation on return or feed lines where a reliable overpressure safeguard is required.

Advantages

The valve provides consistent pressure relief at a fixed 6 bar setting without the need for on-site adjustment. Its threaded 3/4" x 1" connection allows simple mechanical attachment to standard heating system fittings. Constructed for stable operation in water heating circuits, the component reduces risk of damage from overpressure and helps maintain system safety and integrity. The design emphasizes durability and predictable performance under typical heating system temperatures and pressures.

Suitable for

• Closed water-based heating systems and hot-water boilers
• Domestic and small commercial heating circuits
• Protection of heat exchangers, pumps and piping from overpressure

Key specifications

• Connection type: threaded 3/4" x 1"
• Set pressure: 6 bar (fixed)
• Designed medium: water for heating systems
• Application: overpressure protection for closed heating circuits

How to use

Install the safety relief valve on an appropriate branch of the heating system where it will discharge safely to drain or an approved discharge point. Ensure the valve is mounted in accordance with local plumbing codes and manufacturer installation guidance, with correct thread sealing and proper orientation. After installation, test the system slowly to operating pressure and verify the valve remains closed below 6 bar and relieves at or slightly above the set pressure. Periodic inspection is recommended to confirm there are no blockages in the discharge path and that the valve operates freely.

Usage recommendations

Specify installation by a qualified technician and confirm compatibility with system materials and maximum allowable temperatures. Do not modify the valve or attempt to change the set pressure; replace the valve if signs of corrosion, leakage or mechanical wear are present.
