Concentric and eccentric styles as well as our tapered disk design are available for horizontal, vertical applications and are working well without leaking while getting a return pressure. Our special designed Check valve can be using for many applications in such as food, dairy, beverage, pharmaceutical, chemical, and many other industries.
