Product Feature:

1, the disc lift check valve disc, seat around tunnel axis rotation, due to the channel into a streamline in the valve, flow resistance is smaller than l butterfly check valve, suitable for low velocity and flow not often change the large diameter of occasions, but should not be used for oscillating flow, its sealing performance than lift.Butterfly check valve points single type, double disc type and for the most part three, the three forms mainly by the valve diameter, the purpose is to prevent the backflow medium flow or stop, decrease hydraulic shock.


2, lift check valve: disc revolve around pin in the seat of the check valve.Disc check valve has simple structure, can only be installed in horizontal pipe runs, sealing is good.


3, lift check valve: disc sliding along the center line of the body of the valve.Pipeline check valve is a new kind of valve, its small size, light in weight and good processing technology, is one of the check valve development direction.But the fluid drag coefficient is slightly superior to swing check valves.


Applications:Pumping stations. Water treatment and supply. Networks for clean water distribution, irrigation (filtered water). Fire protection networks.

Silent Lift Check Valve

Brief introduction:

The silent resilient check valve is applied to the vertical pipelines in which medium flow runs upwards

and the

back-wards flowing are effectively stopped. It could be widely used in water-supply system and drain system and it works silence.


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.
