The Cla-Val 581 is a silent globe-type check valve designed for water distribution networks and pump stations. The spring-loaded disc closes prior to flow reversal, minimizing hydraulic shock and water hammer events.
Suitable for pump discharge lines, fire pump stations, vertical turbine pumps, booster stations in high-rise buildings, and house pump systems. Compatible with potable water and other non-corrosive media.
Valve selection should consider:
Requires full-face gaskets and concentric flanges. Bolts should be tightened in a cross-pattern. Seat and disc are field-replaceable, reducing downtime during maintenance.
Where is the Cla-Val 581 typically used?
Installed in water pump stations where rapid closure is required to prevent flow reversal.
Is a soft seat option available?
Yes, Buna-N resilient seat is available for specific applications.
Can it be installed vertically?
Yes, suitable for both horizontal and vertical installation per manufacturer guidelines.
The Cla-Val 581 Series Silent Globe Check Valve has a spring-loaded poppet that allows the valve to close before flow reversal occurs, resulting in a silent, non-slam closure.
Constructed of a cast iron body with bronze trim, the Cla-Val Silent Globe Check Valve offers watertight shutoff with metal-to-metal seating. For special applications, stainless steel trim is available and Buna-N® resilient seats are available as options.
