Application fields:<br />

OLYMPIC series is suggested in the case of frequent interchangeability of components,<br />

e.g. for maintenance reasons.<br />

It is usually employed for gas and water distribution, industrial and civil heating, water<br />

plants, hydraulics and pneumatics, oil and petrochemical fields, non aggressive media.<br />

Connections:<br />

• Standard Flanges to UNI 22<strong>40</strong> and 2229 (sealing raised face PN 16)<br />

overall length to ISO 5752 (table 6 medium series PN 16)<br />

Operation devices:<br />

Aluminium lever. Available colours: black, yellow.<br />

SPECIFIC FEATURES:<br />

• the OLYMPIC valve with full bore, manufactured according to international<br />

standards, is of the type bolted with connection round flanges<br />

• does not need any maintenance, is equipped with wrapping seats ensuring<br />

long life cycles<br />

• four self-adjusting cone-shaped seals, with PTFE-PTFE sliding, therefore without<br />

wear, form two sealings with automatic functioning<br />

• an adjusting gland allows the sealing reset on the stem<br />

• all valves are tested according to a strict procedure covering severe<br />

inspections on the entire production.<br />
