Boiler Drain Valves

Boiler drain valves, also known as drain cocks, are designed for use with boilers, water heaters and storage tanks to drain water from a plumbing or heating system. Raptor Supplies offer a wide range of these drain valves from brands like Watts, Proline and Webstone. These valves feature a full-flow design with a maximum pressure rating of 125 psi WOG. Boiler drain valves from Watts are ideal for use in hydronic heating systems and feature brass construction with 3/4 inch hose thread connection on the outlet. They are further equipped with an adjustable Teflon stem packing for providing positive shut-off and an aluminium quarter-turn tee handle for manual control. Choose from a wide variety of these drain valves available in brass, celcon(R), CPVC, forged brass and low-lead brass body materials, on Raptor Supplies.

Working Mechanism

  • The valve has a handle or lever that can be turned to open it and release the water & sediments.
  • When the valve is open, the water & sediments can flow out of the boiler and into a drain or other appropriate disposal area.
  • Once the water and sediments have drained, the valve can be closed to seal the system again.

Frequently Asked Questions

What is the difference between a boiler drain valve and a boiler blowdown valve?

A boiler drain valve releases water and sediments accumulated in the bottom of a steam boiler while the boiler blowdown valve, on the other hand, releases water containing high levels of dissolved solids.

How to avoid backflow?

Boiler drain valves can be fitted with a backflow prevention device to prevent water from flowing back into the boiler.

How can I prevent my boiler drain valve from freezing in cold weather?

If your boiler is located in an unheated space or in an area where the temperature can drop below freezing, the water in the drain valve can freeze. To prevent this, make sure that your boiler is insulated and that the drain valve is located in a location that is protected from the cold.
