Thomas & Betts DBV-1/4 – Frequently Asked Questions
1) What thread size does the Thomas & Betts DBV-1/4 ball valve drain use?
The DBV-1/4 is a 1/4 inch hub size fitting, and both the drain adapter and the ball valve carry a female NPT threaded connection so you can thread on a drain tube and route the liquid where you want it. Order your tube nipple to match that 1/4 inch NPT.
2) Is the DBV-1/4 drain valve suitable for washdown enclosures?
Yes. When the T&B drain adapter is assembled with this ball valve, the assembly is rated UL Type 4X, which is what you need for washdown areas. The body is Type 316 stainless steel for corrosion resistance in those environments.
3) Can this drain valve be used in a food or beverage plant?
It can. Both the T&B drain adapter and the ball valve are NSF Certified for food and beverage applications, and the wetted parts are 316 stainless, which is the grade specified for sanitary and corrosive duty.
4) Do I need anything else besides the DBV-1/4 to drain an enclosure?
Yes, the ball valve is not a standalone drain. It assembles onto the T&B drain adapter, which is what mounts into the enclosure wall; the valve then gives you the ability to open, close and inspect the drainage. If you want the liquid directed away from the box, add a drain tube to the 1/4 inch female NPT outlet.
5) How much room do I need around the enclosure to fit the DBV-1/4?
The valve itself is small: 2.03 inches long and 0.75 inch wide, at 0.19 lbs. The matching T&B drain adapter uses a compact body and a special-grade silicone gasket so it will seat in tight spaces and even on curved enclosure surfaces, but you still want clearance below for the valve handle and any drain tube.
6) Should I use a plain drain breather or add a ball valve like the DBV-1/4?
A plain drain and breather fitting vents and drains continuously with no way to shut it off or verify it. The DBV-1/4 valve threads onto the T&B drain adapter so you can control and inspect the drainage process, and it lets you pipe the discharge away through a tube. Pick the valve where you need to confirm the drain is clear, capture the liquid, or stop flow during cleaning; a bare drain breather is enough on a dry indoor box.
7) Will a drain valve clog if the enclosure collects oil or debris?
The T&B drain design uses large drain orifices, an integral breather, and has no moving parts in the drain path, so it keeps working with viscous liquids or small debris. Adding this ball valve on top lets you flush or inspect the drain manually instead of waiting to see whether it is passing.
8) Does the DBV-1/4 ball valve come individually or in a multi-pack?
It ships as a single piece (inner quantity of 1), with 5 pieces to an outer carton. If you are standardizing drains across a run of enclosures, the five-pack carton is the full master pack.
