Self-Closing Valves Malleable Iron Flanged Straight With Handle DIN PN 16
TECHNICAL CHARACTERISTICS
Self-closing valves are most often used in water or fuel systems, where the valves are normally open and can be activated by a handle that releases a spring closing the valve. In addition, the valves can also be used as ordinary shut-off valves, closing with the standard handwheel. Seal – metal / metal.
WORKING FLUIDS / MEDIUM
Water, thermal oil, fuels, oils, flammable hydraulic oils, non-flammable hydraulic oils, petroleum, boiler feed water, condensate and seawater.
EXECUTION
