Product Name: Pressure Seal Lift Check Valve
Design Standard: API 602
Body Material: ASTM A105N
Size: 2 Inch, DN50
Pressure: Class 2500 LB, PN420
End Connection: Socket Weld

Pressure Seal Check Valves are designed and manufactured in strict accordance with international standards, including API 602, ASME B16.34, or equivalent. These valves minimize flow resistance and pressure drop, making them ideal for use in horizontal positions only. The lapped and screwed seat ring ensures a tight seal and long service life. The valve's disc is precisely designed, machined, and guided to provide efficient automatic shutoff even at zero pressure. Additionally, the valve features a compact structure and low-emission service, available in both swing and piston constructions.
