The body and the disc when the determined flow in the system starts.
The disc hinged on the body is placed within the flow section.
Halves stainless steel disc, which are positioned in the body seats on sealing EPDM gaskets and provides 100% tight sealing.
Expanders shorten and halves discs lap and let to flow between the body and the disc when the determined flow in the system starts.
With the start of movement at defined flow direction on the system, the disc leaves the flow section by turning in its axis and allows the flow pass.
When the flow stops, the disc sits on the EPDM sealing rings placed on the body through disc spring force and maintains 100% tight sealing.
Deigned to maintain the minimum head loss on the pipeline.
Through its short installation length and eye screw (hook), easy to install between two flanges.
A partially open disc creates an obstruction that produces a higher pressure drop and fluttering of the valve disc – disturbing the flow and increasing the chance of water hammer.
Constructed with stainless steel disc.
Can be installed in horizontal or vertical position
