Ductile Iron Silence Globe Needle Check Valve Flange End Epoxy Coating
 
 
The Silent Check Valve is the preferred choice in applications where silent operation and cost are major concern.
 
Its short linear stroke and spring return action combine to close the valve prior to flow reversal which effectively eliminates the shock and water hammer normally associated with the sudden stoppage of a reverse flow.
 
Features: 
⊙Professional design
The inner cavity of valve is designed as streamline shape, which can effectively stop the turbulence. The spherical surface is introduced to form the front of disc and cone contact for the seating couple; these structures will extremely the shock force of medium and decrease the resistance coefficient of flow.  Thin shell structures is employed when design the diversion component to ensure the laminar flow and greatly drop the weight.  The reasonable open height and cavity space enable the obtaining of maximum area of flow section.  It can avoid occurring of the air chamber; the valve parameter Cv is improved.
⊙Excellent proof corrosion characteristics
Internal and external epoxy resin coating.                      
⊙Reliable hygiene principles
Epoxy resin and rubber comply with hygiene standard, the trim, such as disc, spring, etc., are made of stainless steel.
