Non-Slam
Tilting Disc 
Check Valve

Designed for high-performance flow control, this valve features a tilting eccentric disc combined with a hydraulic damper to ensure smooth, non-slam operation. The eccentric disc design minimizes contact with the seat during opening and closing, reducing wear and extending service life. When closing, the disc tilts gently into position, assisted by the hydraulic damper which controls the speed and prevents sudden shutoff. This eliminates water hammer and protects the pipeline from pressure surges. Ideal for pumping stations, water transmission lines, and critical applications requiring quiet, shock-free operation, this valve offers durability, reliability, and long-term performance.
