DANFOSS drain valve with chrome handle 3/4"

The DANFOSS drain valve with chrome handle 3/4" is a manual valve intended for controlled draining or venting in plumbing and heating systems. It provides a dedicated access point for releasing water, bleeding radiators or sections of pipework, and performing maintenance tasks. The chrome-finished handle offers corrosion resistance and a firm grip for straightforward operation in residential and commercial installations.

Advantages

The valve is designed for reliable manual operation, combining a robust body with a chrome-plated handle that resists corrosion and wear. Its 3/4" connection size makes it compatible with common pipe fittings, and its simple mechanism allows precise control over flow during draining or venting procedures. The compact design enables installation in tight spaces and integration with existing plumbing and heating systems.

Suitable for

• Draining water from boilers, radiators and pipe sections
• Bleeding air from heating circuits
• Temporary system isolation for maintenance or repair
• Use in domestic and light commercial plumbing and heating installations

Key specifications

• Connection size: 3/4"
• Operation: manual
• Handle finish: chrome-plated for corrosion resistance
• Application: drain and vent point for plumbing and heating systems
• Mounting: inline or at designated drain points depending on system layout

How to use

Install the valve at the system's designated drain or bleed location using compatible 3/4" fittings and ensure all connections are tightened to correct torque to prevent leaks. To drain or vent, position a suitable container beneath the outlet, open the chrome handle slowly to control flow, and close the valve when the required amount of fluid or air has been released. For radiator bleeding, open the valve until water flows steadily without air; for full draining, keep the valve open until the system is empty. After use, ensure the handle is fully closed and check connections for any sign of leakage.

Usage recommendations

Use corrosion-resistant sealing materials compatible with the system fluid and perform periodic inspections to ensure the handle and body remain free of scale and corrosion. Operate the valve slowly to avoid water hammer and wear protective gloves when handling hot fluid. For pressurised systems, isolate and depressurise the section before full removal or replacement of the valve.
