Key Specifications / Features

Model No. : 185301008

This API 600 Class 800 piston check valve is forged from ASTM A105N carbon steel with a bolted bonnet and butt-welded ends for high-pressure industrial piping. Its piston-style disc automatically opens under forward fluid flow and closes tightly to stop backflow, protecting pumps and equipment from reverse flow damage. With hardened seat trim, it works reliably for steam, oil, and gas media up to 425℃. The raw forged surface maintains high structural strength, complying with ASME B16.34 for strict process service requirements.
