Super Check

Two semi-circular plates are mounted to the valve body by a hinge pin. When the fluid flows, each plate opens in a V shape centering on the hinge pin and fully opens up to the stop pin.

Characteristics of Super Check Valve

Short face to face dimensions
It is easy to install and remove the valve to/from the piping at a narrow space.
Light weight
In comparison with the convensional check valves, Astam Check Valves can reduce a burden for the piping.
Simple structure
It is easy to maintain because of a small number of assembling parts.
Various materials
Material for the bodys,plates and other parts are abundant variety for the fluid.
Cylindrical structure
Since the structure is cylindrical shape, it is suitable for high pressure.

Kinds of Super Check Valve

C1 type (standerd type) metal seat

Each seat of the valve body and plates is metal to metal ,
therefore, it can prevent the reverse flow under the condition of more high temperature・high pressure.
