fire gate valve DN40-DN600

the elastic valve to compensate for the role of micro-elastic deformation to achieve a good sealing effect.

Main technical parameters:Product Name: attached to the opening instructions resilient seated gate valvesProduct Model: Z45XNominal pressure :1.6-2 .5 MpaNominal diameter: DN40-DN600Suitable medium: waterUse temperature :0-80 degreesFlange standards: GB/T17241.6GB/9113Test Standard: GB/T13927 AP1598Features:Three "O" ring seal: As the stem with three "O"-ring seal not to reduce the frictional resistance when closed, significantly reducing water leakage and can turn off the water construction to replace the seals.    Help to drink: and thus will not rust water or corrosion due to the internal body to non-toxic epoxy resin coating, the valve inner and outer surfaces are completely rubber coated, available to drink.    Valve to ensure that the overall plastic package: valves with high quality rubber sulfide within the overall outsourcing glue, Europe's leading rubber vulcanization technology makes precise geometry, then solid rubber and ductile iron valve, easy to fall off and elastic exchange Yi Jia.    Casting body: The body uses the precision casting, precise geometry of the internal body without any finish to ensure sealing of the valve.    Embedded copper nut: Brass nuts with elastic valves embedded joints, so that the two closely integrated into one, not because of the water flow caused by vibration of loose or damaged phenomenon.    Corrosion resistance: body powder epoxy coating to prevent corrosion and rusting of the body, can be used for the sewage system.    Difficult to fragmentation: the past, traditional cast iron gate valves are often hit by foreign objects, collision or weight caused by the fracture phenomenon. Switch to ductile iron body, such situation could be substantially reduced.
