Ayvaz FPCV-20 Piston Type Check Valve API 602 3/4 inch

Ayvaz FPCV-20 Piston Type Check Valve API 602 3/4 inch

Instant reverse flow protection for high-pressure, high-temperature systems.

Ayvaz FPCV-20 Piston Type Check Valve API 602 delivers uninterrupted protection against reverse flow in superheated steam lines. In addition, its 3/4 inch (DN20) nominal diameter and socket weld connection allow easy integration into precise heat treatment circuits. Moreover, the spring-loaded piston mechanism ensures a tight seal even at the lowest differential pressures.

The valve features a Class 1500 (PN250) pressure rating and withstands temperatures up to +300°C. Its ASTM A182 F22 alloy forged steel body and bonnet provide higher structural integrity than cast alternatives. Furthermore, Stellite 6 hard-coated disc and seat surfaces resist wear and erosion. As a result, the valve maintains leak-tight performance through millions of open-close cycles.

Ayvaz FPCV-20 Piston Type Check Valve API 602 — Technical Specifications

This check valve is particularly suited for thermal power plants, where it prevents reverse flow in superheated steam and feedwater lines. In addition, petrochemical reactors rely on it for safe control of hot oil and reactive fluid transfer. Consequently, industrial steam generators and heat treatment systems also benefit from its reliable protection.

In conclusion, Ayvaz FPCV-20 Piston Type Check Valve API 602 is the ideal choice for reliable high-pressure, high-temperature service. ORFA supplies worldwide and provides technical support and stock availability information.
