Everlasting

Boiler Blowdown Valves | Boiler Supplies

Everlasting quick opening and slow opening repair kits for boiler blowdown valves are listed on BoilerSupplies.com. The complete Everlasting blow-off valves sit in the BoilerSupplies.com blowdown and blow-off valve category. The kits go to mechanics rebuilding a blowdown valve that no longer shuts tight. Read the tag on the valve for size, type (quick opening or slow opening) and pressure class before ordering. Match the kit and order it, or send the tag details and ask for a quote.

About Everlasting Blowdown Valve Repair Kits

Everlasting Valve Company of South Plainfield, New Jersey, makes boiler blowdown valves built around a rotating disc rather than a wedge or plug. The valves handle bottom blowdown on steam boilers. Scale, sludge and high velocity discharge cut an ordinary gate or globe valve seat there.

BoilerSupplies.com carries the Everlasting quick opening and slow opening repair kits on its Everlasting page. The complete Everlasting blow-off valves are listed in its blowdown and blow-off valve category. A kit is matched to the valve it goes into: quick opening or slow opening, valve size, and the pressure class stamped on the body. In a tandem pair the slow opening valve does the throttling and takes the wear.

Do blowdown valve and blow-off valve mean the same thing on a boiler?

Yes: blowdown valve, blow-off valve, bottom blow-off valve, boiler drain valve and blowdown cock all name the same valve on a steam boiler. It sits at the lowest point of the boiler and discharges sludge and scale to the blowdown tank. Everlasting makes them in quick opening and slow opening types, and the repair kits on BoilerSupplies.com fit those two types.

What do you need from me to pick the right Everlasting repair kit?

Start with the markings on the valve body or tag: the valve size, whether it is quick opening (lever) or slow opening (handwheel), and the pressure class. A photo of the valve and its tag is the fastest way to get all of that across. Add the quantity and BoilerSupplies.com can match the kit or quote it.

Is my Everlasting blowdown valve worth a repair kit instead of a new valve?

A repair kit is the answer where the body is sound and the valve just will not shut tight or drips into the blowdown line after closing. A cracked body, a stripped stem thread or a valve that has been welded on needs a new valve. Take the bonnet off during a cold outage and look at the disc and seat before deciding.

Do the repair kits fit both quick opening and slow opening Everlasting valves?

No single kit fits both: Everlasting repair kits are listed by type, one for quick opening valves and one for slow opening valves. A kit fits the type and size it is listed for. Order the kit that names your valve type and size. Send the valve markings if the type is not clear from the handle, since a lever and a handwheel are the usual tell.

Where are the complete Everlasting blowdown valves on BoilerSupplies.com?

Complete Everlasting blowdown valves are listed in the BoilerSupplies.com blowdown and blow-off valve category, beside the other quick opening and slow opening blowdown valves there. This Everlasting page holds the repair kits. To replace the whole valve, add the end connection to the size, pressure class and type.

A photo of the valve and its tag, plus the quantity, is all a quote takes: send it through BoilerSupplies.com, or call 1-770-957-9599 (toll free 1-800-780-3776).

In-stock orders eligible for small-pack shipments placed before 2:00 PM EST, Monday through Friday, will ship the same day. If ordered after 2:00PM EST, it will ship the following business day.
