The Cast Carbon Steel Non-Return Valve (NRV) Class 150, Swing Type with Bolted Cover, is engineered for efficient backflow prevention in high-performance pipeline systems. Built from cast carbon steel (WCB), this valve delivers exceptional strength, corrosion resistance, and durability under demanding pressure and temperature conditions.
The swing-type disc mechanism allows free forward flow and instantly closes upon flow reversal, minimizing water hammer and protecting equipment. The bolted cover design ensures ease of maintenance and long-term reliability, making it ideal for applications in oil & gas, steam lines, water supply, chemical processing, and power generation.
Key Features:
Valve Type: Swing Type Non-Return Valve (NRV)
Pressure Rating: Class 150
Body Material: Cast Carbon Steel (WCB)
Disc Material: Stainless Steel / Carbon Steel
