Wafer tilting disc check valve is designed to open at 1 psi of pressure and withstand pressures up to 150 psi. The entire valve is a cast design for better strength and stability. Sizes from 2" through 40" and in body materials ranging from carbon steel, low carbon steel, stainless steel, and duplex, The Vatac Wafer Ends Tilting Disc Check is an excellent choice for raw water, cooling water and treated water/wastewater applications. Its streamlined body contouring, flow area 40% greater than nominal pipe size and hydrodynamic disc combine to provide the lowest headloss of any check valve produced today.

TYPICAL DESIGN FEATURES ON VATAC WAFER TILTING DISC CHECK
» Small face to face dimension
» Light weight for easy site installations
» Allows opening at low pressure differentials
» Tight shut-off resilient seated design to “Zero” Leakge
» Metal to metal shut-off at both high and low pressure differentials

MAIN ADVANTAGES
» Suitable for all usable flange standards
» Short face-to-face length invaluable where space is limited
» Low weight results in low handling costs and ease of installation
» Low pressure drop and low opening pressure
» Fully open with small water velocity, without closing spring
» Excellent tightness
» Rapid response - oblique seat reduces closing travel
» The circular wafer body is designed to be clamped between two pipe fl anges.
» The valve disc is suspended on two heavy stub shafts with the selected suspension points giving the fastest closing possible.
» The stub shafts are sealed externally by integrally welded plates.The seat is oblique in order to give a short closing travel and thus a short closing time.
» Spring Loaded Construction reduces water hammering

APPLICATIONS IN THE AREAS BUT NOT LIMITED TO
