Resilient Sealing Gate Valves

Hamoun Nyzeh (HANYCO) is manufacturer of ductile iron pipes and fittings, with the ap­proach of producing and supplying pipes and fittings for water and wastewater projects, from DN 80to DN 1200 mm in diameter, with a nominal production capacity of 120,000 tons annually. The new product of Hanyco is Ductile Iron Resilient Wedge Gate Valves with the following specifications produced by the "Lost Foam Casting" process in a fully automatic production Line.

Nominal sizeDN (50-80-100-200)

Working pressure PN 10/I6 bar

Resilient Wedge Gate Valves Applications

The Hanyco butterfly valve can be used for wide range of applications including raw, cooling g and drinking water up to 120 C and air conditioning facilities to isolate or regulate of the water flow Thanks to numerous material options for the valve's disc and seal, special application cases can also be realized without any problems. They are available in nominal sizes from DNS0 t DN200 with Working Pressure 10/16 bar. The use of butterfly valves on transmission lines as a flow controller is not permitted and must be fully open or fully closed. The design of the valve is such that the disc is fully centered in the open position and provides the best conditions for the flow with the lowest pressure loss. This valve is suitable for installation between flanges which prepared accordance with DIN EN 1092-2 and operating pressure up to 16 bars.
