Body and Cover : GG-25 Cast Iron / Handwheel: GG-25 Cast Iron / Gasket: EPDM / O-ring: EPDM / Spindle: Stainless steel / Segment Gear : GG-25 Cast Iron . ** Connection Type: Flanged / Working Pressure :175-300 PSI / Working Temp.:-10ºC , + 120ºC / Working Test Pressure : 600 PSI *** NRS gate valve is developed to be used as the cut off and zone control valves in order to substitute supervisory switched butterfly valves and OSY rising stem valves in the fire security systems. These valves are usually burried underground to prevent the risk of freeze. Just to make them visible and traceable inside the systems, they are preferred to be used with post indicators instead of wheels. **** Application Areas: In fire fighting systems, which is non-affected by freeze, than they are using under the soil.

The sliding gate motor valve type 8038 in reinforced design with highresolution fast actuatoris suitable for a wide range of process applications. Media such as steam, liquids, gases, etc. can be handled precisely. The interaction of highprecision control electronics with the precise stepper motor results in a positioning accuracy of ± 0.2% even with a valve stroke of only 6 mm. By means of supercapacitor technology, in the event of a power supply failure, the valve returns to its defined basic position. Metal bellows Position electronics Analog stroke feedback Limit switch Fail safe feature
