Cast Iron Armature - Model 144 Series -Globe Valve for Ammonia

The valves are ? pipeline fixture for letting out, stopping, and fluid stream regulation, whose shutting device moves perpendicular towards the sealing rings (the saddle). They are implemented as shut-off devices in refrigeration installations, through which is transported liquid or gaseous ammonia, at pressure not exceeding PN 16. This type can be used in other cases, where higher density of thesealing surfaces and the gland chamber are required. There is possibility for change of the gland packing under pressure. In case of full open valve the Teflon ring of the stem provides sealing with the bonnet. Operation temperature is from -40°? to 120° ?.
