The 3-inch Single Plate Check Valve features a mild steel body and disc with a Nitrile (NBR) soft seat for dependable, leak-free backflow prevention. Designed for compact wafer installation, it offers low pressure loss, quick closure, and durable sealing performance…
The Single Plate Check Valve – 3 Inch (DN80) is engineered to deliver efficient non-return (NRV) performance in industrial and commercial pipeline systems. Its spring-loaded single plate design enables quick shutoff when flow reverses, protecting pumps and pipelines from backflow damage.
Manufactured with a mild steel body and disc, the valve ensures mechanical strength and resistance to wear. The Nitrile rubber seat (NBR) provides a soft, tight seal for superior leak protection, even under low-pressure conditions.
The wafer-type body makes this valve compact, lightweight, and easy to install between standard flanges, reducing installation space and overall system cost.
Suitable for water supply, HVAC, fire-fighting, and general process industries, this valve offers a perfect balance of performance and economy.
