Threaded Flow-Adjustment Valves
These valves gradually open and close to adjust and regulate flow.
Lever handles open and close faster than wheel handles.
Flow-indicating lever handles show the proportion the valve is open.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
- Valve Type: Butterfly
- For Use With: Water, Oil, Air, Argon, Helium, Krypton, Neon, Xenon
- Specifications Met: CSA Certified, CSA-US Certified, UL Listed

Drain Valves
Also known as stop cocks, install these valves on your tank for easy draining of air or fluid.
Inline handles can be operated from any position. The handle surrounds the drain outlet, so liquids may splash onto your hands or the handle. Side handles are out of the way of the flow, so your hand and the handle stay dry.
Valves with an external seal are for higher flow applications than valves with an internal seal. They also have a longer valve stem, so they’re less likely to introduce contaminants from exposed threads. Valves with an internal seal have shorter stems than those with external seals, so they fit shorter clearances. However, they’re more likely to introduce contaminants to the tank from debris collected on the exposed threads.
Valves with a brass body won’t corrode when venting air or draining water—even in wet or humid environments.
Brass handles won’t corrode.
Valves with a wing-nut handle give you leverage to open tight, stubborn valves that have been sealed for long periods of time. The wings on these handles face inward, so they have a lower profile than handles with outlet-facing wing nuts.
Valves with a tube outlet can be attached to a tube or hose to route the flow of draining liquid.

Valves with a wing-nut handle give you leverage to open tight, stubborn valves that have been sealed for long periods of time. The wings on these handles face outward, so they fit tanks without enough clearance around the drain hole to fit handles with inlet-facing wings.
A spout outlet smoothly pours any draining liquid into buckets without splashing.
