Mazzei MV-5 NPVDF 1/2" Metering Valve with V Port Control
Precision flow control valve with characterized V-port seat for consistent chemical dosing in venturi injector systems
The Mazzei MV-5 NPVDF metering valve features a customized V-port characterized seat that delivers linear flow control across a wide range of injection rates. Built from natural-colored PVDF (polyvinylidene fluoride), this valve provides superior chemical resistance and precise control for adjusting chemical feed rates in Mazzei venturi injector applications.

System Integration
The MV-5 NPVDF metering valve is designed specifically for use with Mazzei venturi injectors to regulate chemical feed rates in fertigation, water treatment, and industrial dosing applications. The 1/2" NPT female ports integrate directly with Mazzei injector discharge lines and chemical supply tubing. PVDF construction offers excellent resistance to acids, bases, chlorine, and most agricultural chemicals. This natural-colored version allows visual confirmation of fluid flow and helps distinguish it from black valves in multi-injector installations.
