Silence Lift Stainless Steel Check Valve Resilient Seated WCB Body Material

Guaranteed performance0 General;
o The silence resilient seated check valve is applied to the vertical pipelines in which medium flow run supwards and the back-wards flowing is effectively stopped. It could be widely used in water-supply system and drain system and it works silence.
Professional design:
o The inner cavity of valve is designed as streamline shape ,which can effectively stop the turbulence.
o 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.O Thin shell structures is employed when design the diversion component to ensure the laminar flow and greatly drop the weight.
o The reasonable open height and cavity space enable the obtaining of maximum area of flow section.
O It can avoid occurring of the air chamber; the valve parameter Cv is improved
Excellent proof corrosion characteristics:
O Internal and external epoxy resin coating.
Reliable hygiene principles:
o epoxy resin and rubber comply with hygiene standardGB/T17219-1998.
o The trim, such as disc, spring, etc., are made of stainless steel.
Suitable application:
OWater-supply system ,drain system and heating system
