Magic Plastics 0801-20H2 2 in. CR2 Corrosion-Resistant Check Valve
Brand: Magic Plastics | SKU: 0801-20H2
Product Overview
The Magic Plastics 0801-20H2 CR2 Check Valve is built for 2-inch circulation systems where chemical exposure makes corrosion resistance especially important. Magic Plastics developed the CR2 family to help protect equipment such as heat exchangers from backflow associated with inline chlorination while maintaining a full-flow circulation path.
The valve uses a Hastelloy spring, glass-filled Noryl shaft, silicone gasket and a clear serviceable lid. A 1/2 lb. spring-loaded gate allows flexible installation orientation, while the clear lid provides access for inspection and service.
