Minimizing the pressure loss of wafer type swing check valve ASME 79/MA NE 5. These results primarily the optimum valve diameter and elliptical inlet shape have been incorporated into the Bray/Rite design. Like a venturi, the aerodynamic shape accelerates the line media through the valve with the lowest possible pressure drop.
The low pressure drop of the Bray/Rite valve was achieved by Ritepros many years of research and developmentbination with universities and federal research agencies. Several theses and papers were published including minimizing the pressure loss of wafer type swing check valve ASME 79/MA NE 5. These results primarily the optimum valve diameter and elliptical inlet shape have been

Therefore high pressure check valves such as are encountered in steam and high pressure process services tend to be other designs than the swing type. In small sizes, the opposite problem exists. Although the fluid flow provides most of the force to close a check valve, gravity is also required most of the time. Small check valves, say under 2 in. pipe size, do not have

The Cameron WHEATLEY Series 500 check valve is a fire tested carbon steel flanged end check valve with a full open, through conduit design for low pressure drop and less turbulence.
11/10/2019· Wafer check valves are designed to fit into small spaces between two flanges, where swing check valves may not fit. One other major difference between swing check and wafer check valves is the wafer check valve restricts flow by a greater percentage than the swing check valve.
02/08/2010· Swing check valves cause very little pressure drop and is best suited for low velocity flow service where flow changes are infrequent. If used where high frequency flow reversals are encountered such aspressor and pump service, the disk will have a tendency to chatter, which may damage the valve seats. Swing check valves are furnished in both regular and full opening
The principle of a swing type wafer check is much the same as full bodied versions except when the disc opens it is forced up to a point of contact with the pipe bore. This however means the disc must be smaller than the NPS and thus higher pressure drop is a characteristic. Swing type wafer check valves have the advantage that they are of a
Wafer check valves areg the preferred type of check valve for most applications, due topact design and relatively low cost. Wafe Type Check Valve also can avialble with Spring Loaded Type. Wafer Type Check Valve Single Plate Body Type,
ull Port Wafer Check Valves provide more flow and lower pressure drops than conventional check valves. Our elastomer hinge wafer check valve design takes it to an entirely new level by eliminating the restrictive valve seat and substantially increasing the valves open area and flow coefficient Cv.
The split disc check valve or dual plate check valve is designed toe the size and pressure drop limitations of the swing and disc type wafer check valves. The flap of the swing check valve is essentially split and hinged down its centre, such that the two disc plates will only swing in one direction.
The low pressure drop of the Bray/Rite valve was achieved by Ritepros many years of research and developmentbination with universities and federal research agencies.

These valves produce the lowest pressure drop,pared with other check valves of the same size, the internal contours and shapes allow them to fully open at low fluid velocities and create a smooth flow path through the valve. The design is simple and easy to maintain and can be used for either horizontal or vertical fluid flowing upward pipe layouts. Because of their design, swing
