Features & Benefits:

• Engineered and sized for the application, not the line size
• One piece body casting (no body penetration, no fugitive emission to atmosphere)
• One moving part resulting in minimum wear and long life
• Short stroke length resulting in quick dynamic response and minimizing the reverse velocity through the valve, thus preventing water hammer risks
• Suitable for reciprocating compressor service (removal of chatter effects frequently associated with conventional check valves)
• Stable behavior due to the Venturi type design, the opening characteristics ensure a fully-opened check valve
• Choice of spring torques to suit critical velocity systems and improve valve response time
• Anti-spinning device to stabilize disc
• Tight shut-off
• Maintenance-free design
