Function
A check valve ensures that water only flows in a single direction of a
plumbing or hydronic system. The NA51 series low-lead serviceable
inline spring check valves, ideal for residential and commercial
applications, feature union connections with a variety of end connection
options for easy installation and maintenance. The valve is constructed
of a stainless steel body and low-lead brass or copper tailpieces. It
complies with low lead laws and listed by ICC-ES, and meets codes
IPC, IRC, UPC and NPC for use in accordance with the US and
Canadian plumbing codes.
