The Mosmatic 90.058 Check Valve is a stainless steel (INOX) valve designed for low-pressure activation, ideal for sensitive fluid control systems. Featuring a soft spring, the valve opens at ~1.5 psi and closes around 2 psi, enabling smooth, low-resistance flow while preventing backflow.
With a 1/4\\” NPTF inlet and a 3/8\\” NPTF outlet, this model offers a stepped connection and supports pressures up to 5000 psi—perfect for high-demand environments that still require soft-flow performance.
