2350 / DUAL CHECK VALVE - Compañía de válvulas Faf

Features

• 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
• No maintenance needed.
