AYVAZ FPCV-20 Piston Type Check Valve API 602 1 1/4”
Instant reverse flow shutoff and dependable sealing in extreme pressure and temperature service.
AYVAZ FPCV-20 Piston Type Check Valve with its spring-loaded piston system stops reverse flow instantly. Moreover, the ASTM A182 F22 forged steel body resists thermal fatigue up to 450°C. Therefore, it delivers dependable flow control in high pressure lines, and its Class 1500 rating suits superheated steam and reactive chemicals.
A spring-loaded piston mechanism halts reverse flow even at the lowest differential pressure. In addition, Stellit 6 coated disc and seat surfaces prevent erosion during high velocity flow. Consequently, this forged steel construction offers higher structural integrity than cast alternatives, which raises sealing reliability. The valve is socket weld connected for leak-tight installation and follows API 602 and ASME B16.34.
