GMK Tilting Disc Check Valve

Benefits:

• The valve body, guiding fluid, disc with axial movement, and spring components make up a Tilting Disc Check Valve. The medium cannot leak backward because of this product. The pipes must be checked for safety.
• For better fluid performance and reduced flow resistance and pressure, the valve body, disc, and tail vertebra are all built as streamlined channels.
• Third, the high-performance spring materials used in the Tilting Disc Check Valve have outstanding corrosion resistance, oxidation resistance, and mechanical qualities, guaranteeing the springs’ durability and reliability throughout time.
• Fourth, it operates quietly, preventing damage to equipment and pipes from water hammers and other noises that can occur when a valve is opened and closed.
• The disc of the valve opens and closes rapidly in reaction to shifts in fluid pressure, and this is made possible by the valve’s extremely dependable pre-compression spring.

Feature

• Tilting disc check valves produce slightly more pressure drop than swing check valves of the same size. These check valves have a single-piece disc without a hinge. In response to flow forces, the disc pivots about hinge pins that are located within the geometry of the disc and slightly above the center-line of the valve body. Due to the disc rotating onto the seat, the sealing surfaces must be conical. Some tilting disc check valves include a counterweight on the disc, dramatically increasing the disc stability with lower flow rates.
• Tilting disc check valves were designed specifically to minimize the potential for high-energy water hammers. This objective is accomplished by locating the disc center of rotation a short distance from its pivot point, thus allowing the disc to quickly close with flow stoppage or flow reversal. Although it is best to size this valve to be fully open, the disc is reasonably stable under some less than full-open flow conditions.
• When it comes to maintenance, tilting disc check valves are more challenging than swing check valves. To keep seat leakage to a minimum, the conical seating surfaces of the disc and in-body seat must mate well, and the disc pivot location must be precise.
