No. 2330

Nickel-Plated with Buna-S Rubber Poppet

Description

The No. 2330 is electroless nickel plated inside and outside, with all other internal parts of stainless steel. Designed to operate in any position, a sensitive spring has been added to close the poppet automatically. The rubber poppet is fully-formed around a solid steel insert to provide greater strength in commercial applications. Each valve is tested twice for casting integrity and backflow prevention. All valves are 100% American-Made and built to last.

Application

Used as an all purpose check valve for multiple applications, including cold and warm water, ethylene, and glycol. (Same as No. 300)
