2-Way Pressure Balance Mixer Valve

F980V – 1/2" NPT Valve Standard threaded connection using 1/2" NPT (National Pipe Thread), compatible with typical threaded plumbing fittings. F980VPEX – PEX-A Valve Designed with integrated PEX-A inlets for direct connection to PEX-A tubing using cold-expansion fittings (ASTM F1960). What is PEX-A? PEX-A is a type of cross-linked polyethylene tubing, which allows for the highest degree of crosslinking, resulting in maximum flexibility, shape memory, and resistance to cracking from freezing.     PEX-A vs. PEX-B: Key Differences Both PEX-A and PEX-B are types of plastic piping, but: PEX-A is more flexible, making it easier to install—especially in tight spots. It’s better at handling freezing temperatures, because it can expand and return to shape without cracking. If it gets kinked, you can fix it with a heat gun, instead of cutting it out. It connects with a special expanding ring system that creates a super-tight, leak-resistant fit.   Why Choose PEX-A? It’s easier to work with,
