What other names does a continuous blowdown valve go by?

Surface blowdown valve and skimmer valve are names often heard for the valve on the steady bleed line, and metering blowdown valve describes one that lets the operator set the flow. The names are not exact matches, so describe the job when you call. Bottom blowdown is a separate, intermittent job with its own valves. Tasco Continuous Metering Blowdown Valves are for the steady bleed.

What do you need from me to pick a Tasco blowdown valve?

BoilerSupplies.com needs three things from the boiler room to pick a Tasco valve. They are the boiler's operating pressure, the pipe size of the continuous blowdown line, and the make and markings of the valve in the line now. A photo of the installed valve and its connections covers the third. Add the boiler make where the nameplate is readable.

What does a metering blowdown valve do?

A metering blowdown valve sets how much boiler water leaves through the continuous blowdown line. The operator opens it to a chosen position, and the valve can be brought back to that same position after it has been closed or adjusted. That repeatable setting is what separates it from a plain stop valve.

What is continuous blowdown for?

Continuous blowdown keeps the dissolved solids in boiler water from climbing. Steam leaves the boiler and the solids in the feedwater stay behind, so the water grows more concentrated. A small, steady bleed carries some of that water out, and fresh feedwater replaces it. The rate is set at the metering valve.
