Product List |
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
