Description
The Mosmatic 90.038 Check Valve is a brass-bodied valve engineered for applications requiring low opening pressure, made possible by its soft spring (~1.5 psi opening, ~2 psi closing). With a 1/4″ NPTF inlet and 3/8″ NPTF outlet, this model is ideal for fluid systems that need a smooth pressure transition and anti-backflow protection.
Its 3″ length offers added flow stability, while the 4000 psi rating makes it suitable for general-purpose fluid and pneumatic installations.
Applications:
-
Car wash and cleaning systems
-
Light-duty spray and dosing lines
-
Low-resistance backflow prevention
-
Pneumatic and fluid step-up configurations
Features:
-
Brass construction for reliability and economy
-
Soft spring for low-pressure response
-
1/4″ NPTF inlet to 3/8″ NPTF outlet
