Product Name: Forged Piston Check Valve, Bolted Bonnet
Design Standard: API 602
Body Material: ASTM A182 F316L
Size: 1/2 Inch, DN15
Pressure: Class 800 LB, PN130
End Connection: FNPT

Forged Steel Check Valves are built to meet international standards like API 602 and ASME B16.34. They are designed to minimize flow resistance and pressure drop, ensuring maximum efficiency. These valves are meant for horizontal installation only, with a lapped and screwed seat ring that provides a tight seal for long-lasting service. The valve disc is carefully designed, precisely machined, and guided to ensure automatic shutoff even at zero pressure. Available in both swing and piston styles, these valves have a compact design and low-emission service, offering reliable performance in various applications.
