Safety Valve Husty 3/4" 6 bar — pressure relief valve for plumbing systems

The Husty safety valve 3/4" 6 bar is a pressure relief valve designed for domestic and light commercial plumbing systems. It opens automatically when system pressure exceeds 6 bar to discharge excess fluid and reduce the risk of damage to boilers, water heaters, pumps and connected pipework. The valve is intended to help maintain safe operating pressure and support compliance with common installation requirements.

Advantages

This pressure relief valve provides reliable automatic pressure release at a fixed set point of 6 bar, helping to protect heating and hot water equipment from overpressure. Its 3/4" connection size is compatible with widely used pipe fittings, enabling straightforward integration into existing systems. The device is constructed for continuous service in potable and heating circuits and is suitable for vertical or horizontal installation positions as allowed by standard plumbing practice.

Suitable for

• Domestic hot water heaters and gas or electric boilers
• Closed heating systems and central heating circuits
• Pumps and pressure vessels where overpressure protection at 6 bar is required
• Commercial plumbing installations with compatible 3/4" connections

Key specifications

• Rated opening pressure: 6 bar
• Connection size: 3/4" (female/male dependent on installation fittings)
• Function: automatic pressure relief for liquid systems
• Typical application medium: potable water and heating fluids
• Installation orientation: compatible with common plumbing orientations (follow manufacturer instructions)

How to use

Install the Husty safety valve in accordance with local plumbing codes and the equipment manufacturer's instructions. Fit the valve at a suitable location on the system where it can safely discharge to a drain or safe area. Ensure correct thread sealing and secure mechanical connections; use appropriate sealing materials compatible with potable water if required. After installation, perform a pressure test of the system to verify correct operation and absence of leaks. Regular maintenance checks are recommended to confirm the valve remains free-moving and unobstructed.

Usage recommendations

Use this valve only within its rated pressure and media specifications. Do not modify the set pressure. Periodically inspect and, if necessary, replace the valve according to local regulations or equipment maintenance schedules to ensure ongoing safety and compliance.
