Ayvaz FPCV-20 Piston Type Check Valve API 602 1 1/2″
Instant backflow protection for high-pressure and extreme temperature lines.
Ayvaz FPCV-20 Piston Type Check Valve API 602 1 1/2″ delivers absolute backflow protection in critical flow lines. Furthermore, its design stops reverse flow instantly under high pressure and extreme temperature conditions. In addition, the ASTM A182 F22 alloy forged steel body offers superior resistance to thermal fatigue, maximizing flow safety in critical processes.
The Stellite 6 coated disc and seat surfaces prevent wear and erosion completely. Moreover, a spring-supported piston mechanism provides leak-tight closure even at the lowest pressure differentials. Consequently, the Class 1500 rating and DN40 nominal diameter make it ideal for medium-scale installations.
Ayvaz FPCV-20 Piston Type Check Valve — Technical Specifications
This piston type check valve is widely preferred in superheated steam lines at thermal power plants and refineries. Furthermore, it provides reliable backflow protection in oil processing units and compressed gas systems. In addition, its forged steel construction offers much higher structural integrity than cast alternatives, while the socket weld connection ensures leak-tight and durable integration.
Key Advantages
- ASTM A182 F22 alloy forged steel body offers maximum resistance to thermal fatigue
- Stellite 6 coated disc and seat surfaces prevent erosion in high-velocity flow
- Spring-supported piston mechanism ensures full sealing even at the lowest pressure differential
Applications
- Thermal power plants: superheated steam and feedwater lines
- Refineries and petrochemical plants: high-temperature flow control
- Oil processing lines and compressed gas systems: backflow prevention
As a result, the Ayvaz FPCV-20 Piston Type Check Valve API 602 1 1/2″ is the ideal solution for maximum flow safety and long-term operational efficiency in petrochemical and energy facilities.
