Valveco Swing Check Valves from HMA Flow & Industrial feature:

• 100% unrestricted flow area for improved flow characteristics and lower head loss.
• One-piece precision-moulded steel disc reinforced with nylon and backed by a 25-year warranty.
• Memory-flex disc is the only moving part for long life and minimal maintenance.
• Full-sized top-access port allows disc removal without removing valve from the line.
• Integral O-ring on the disc ensures positive seating at high and low pressures.
• Short disc stroke, combined with memory flex disc action, reduces potentially destructive water hammer.
• Backflow capabilities are available by means of an optional screw-type backflow actuator.
• Every Swing-Flex Check Valve is 100% tested, including a seat test to ensure drop-tight sealing and hydrostatic testing to ensure casting integrity.
