Brass Threaded In-Line Check Valve (101-305NL) by ProLine0. Size: 1". Connection: FIP x FIP. ProLine Plumbing Valves provide trusted performance for a variety of residential, commercial and industrial flow control applications including use with steam, water, oil or compressed air.

Brady check valves are for use in nearly every water well/irrigation system imaginable. The main use is to prevent wter pumps from losing their prime. This is the main cause of pump failure. They can be used in vacuum systems as well as any other application where backflow prevention is desirable. Brady check valves utilize a unique, patented internal design which allows up to 50% more flow than ordinary check valves. Made of high strength acetal polymer, they are noncorrosive, environmentally safe, and will outlast most metal valves.

Brass Threaded In-Line Check Valve (101-306NL) by ProLine(R). Size: 1-1/4". Connection: FIP x FIP. ProLine Plumbing Valves provide trusted performance for a variety of residential, commercial and industrial flow control applications including use with steam, water, oil or compressed air.

Brady Check Valves are designed to prevent back flow and loss of prime, while providing the most efficient flow. Constructed of one piece polymer body, poppet and diffuser with a Buna-n-Seal, Female x Female threads. For use in areas where codes specify spring loaded Check Valve, Brady model SLC features a 316 stainless steel spring added to the poppet for positive sealing. Made of high strength acetal polymer, they are non-corrosive, environmentally safe, and will outlast most metal valves. Exclusive nose-cone design reduces turbulence and permits 30 to 50% more water flow than comparable valves. A true double seat action. The two seat action is doubly assured under the roughest conditions.
