Product Name: Y Type Check Valve, Pressure Sealed
Design Standard: API 602
Body Material: ASTM A182 F304
Size: 1/2 Inch, DN15
Pressure: Class 2500 LB, PN420
End Connection: FNPT
Pressure Sealed Check Valves are meticulously designed and manufactured in strict compliance with international standards such as API 602 and ASME B16.34 (or equivalent). These valves are engineered to minimize flow resistance and pressure drop to the lowest possible extent, making them ideal for horizontal installation only.
The lapped and screwed-in seat ring ensures a tight seal and extended service life. The valve disc is precisely designed, accurately machined, and expertly guided for efficient automatic shutoff at zero pressure. Featuring a compact structure and low-emission performance, these valves are available in both swing and piston configurations to suit various applications.
