Disc Check Valve (Non-Slam)
Product Range
Disc Check Valve (Non-Slam)
The Disc Check Valve (Non-Slam) offered by Sparkey Valve and Fitting Pvt. Ltd. is engineered to provide highly efficient and reliable backflow prevention while eliminating the risk of water hammer. Unlike conventional check valves that rely on gravity or flow reversal, this valve uses a spring-assisted disc mechanism that closes rapidly upon reduction or reversal of flow. This swift closure minimizes fluid shock, protecting pumps, pipelines, and process equipment. The non-slam operation ensures quiet system functioning, making it particularly suitable for high-speed fluid transfer applications.
Compact Disc Check Valve PreventingReverse Flow and Hammer
Manufactured using premium-grade materials such as stainless steel, carbon steel, and alloy steel, the Disc Check Valve delivers excellent performance even under high pressure and temperature conditions. Its compact and lightweight wafer-style design allows easy installation between flanges, significantly reducing space and material requirements.
Each valve from Sparkey Valve and Fitting Pvt. Ltd. is designed and tested according to strict international standards such as API, ASME, and DIN. With optional sealing materials including PTFE, EPDM, and NBR, this valve offers enhanced compatibility with a wide range of media such as water, steam, gas, oil, and chemicals. Its low pressure drop characteristics improve overall system efficiency, contributing to energy savings in high-capacity industrial networks. The Disc Check Valve (Non-Slam) is widely used across industries such as water treatment, power generation, petrochemical, oil and gas, HVAC, fire protection, and industrial processing systems. severe pressure surges.
