Product Description
The ball check valve model 702 is designed to ensure unidirectional flow in installations where the following are important:
-
High resistance to contamination and solid particles
-
Maintenance-free operation and reliable performance
-
Long service life even under harsh process conditions
The valve’s design allows for automatic shutoff of the flow using a freely moving ball that shifts due to pressure differences. The absence of complex mechanisms makes this valve extremely durable and easy to operate, even in aggressive or particle-laden environments.
Design features of the model:
-
Intended for industrial installations with water, wastewater, contaminated or chemically aggressive liquids
-
No spring – the ball operates based on pressure differential
-
Self-cleaning ball available (in versions with appropriate surface finish)
-
Low pressure drop thanks to simple flow geometry
-
Easy maintenance – access to internal components without removing the valve from the pipeline (in flanged and bolted versions)
Working media:
-
Water, wastewater, liquids with suspended solids
-
Petroleum products, oils, gasoline
-
Acids and alkalis (depending on material version)
-
Chemically aggressive media (including those with phosphates, sulfur)
-
Liquids containing solids: sand, coal, sludge
