Features and applications
The ball check valve is extremely reliable in both vertical and horizontal installations thanks to its simple design and absence of mechanical parts.
Its working principle is based on the free movement of the “ball” inside the valve body and the particular design of the ball guide and of the pipe guarantee a complete opened passage without obstruction or asperity that could catch some solids.
Thanks to the free passage, lost of charges are very low.
The valve’s balls guarantees a minima inertia
and the opening pressure of the check valve is
about the half of the clapet valve type and the
pipe remains opened without the application
of spring or other mechanical supports.
To guarantee perfect sealing and silent running,
the ball is the phenolic resin or coated with
rubber resistant to clean fresh or sea water, waste
water or rainwater even with residual hydrocarbon.
The extremely simplified project assure the valve free from service.
