Excess Flow Check Valve


Available in Brass, SS, SS 316, and Monel.


Designed for protection of system handling noxious, toxic or flammable fluids. The valve assures automatic protection from liquids or gas flows beyond pre-determined limits. When Valve’s predetermined flow-rate is exceeded, a spring-loaded poppet closes automatically, instantly. It remains closed as long as system imbalance remains across the valve. When normal equilibrium Is restored, the valve resets automatically and normal flow resumes.
