The TYPE 5220 & 5320 flanged and TYPE 5321 welded ends ball valves are intended for isolation of medium

flow in industrial systems, heating systems and other systems. (Group 2 fluids, ref. Directive 97/23/EC). The

valves can be operated both in underground and overground installations as installed in vertical or horizontal

pipelines.

NOTE:

Due to the limitations caused by application of specific materials in various operating environment

types, it is critical to precisely determine the operating conditions, i.e. the temperature, pressure and

medium characteristics. This will eliminate any problems during operation of the valve.

The ball valves are intended for isolation of medium flow in industrial systems, heating systems, and other

systems. (Group 2 fluids, ref. Directive 97/23/EC). The TYPE 5220, 5320 & 5321 steel and cast iron ends valves

are designed for operating temperatures of +160°C maximum. The operating parameters of each valve are indelibly

marked on the valve body.

Nominal diameter (dimension) and nominal pressure PN range:
