ART. 101

Product catalog summary

Specifications:
The document describes a 2-way full-bore threaded-ends brass ball valve, suitable for medium pressures with non-aggressive fluids. The working temperature range is from -20°C to +150°C. The valve can handle various fluids including air, water, gas, oils, petroliferous and petrochemical products, and vacuum. It features female threaded ends as per UNI/ISO 7/1 Rp specifications and a valve head conforming to ISO 5211 standards. Special versions with NPT threaded ends are available upon request.

Certifications:
The valve complies with the European Directive 97/23 EC “PED” and an ATEX version is available in conformity with directive 94/9/EC upon request.

Performance and Dimensions:
The document includes a pressure/temperature diagram and a flow-pressure loss diagram with Kv nominal coefficients. The Kv value indicates the flow rate in m3/h that causes a pressure drop of 1 bar with water at 15°C. The document provides detailed dimensions for various valve sizes, ranging from 1/2” to 3”.

Materials:
The valve components are primarily made of brass, with some parts treated with bright nickel plating. Specific materials include FKM for O-rings and PTFE for seals and antifriction rings.

Actuation Options:
The document details options for electrical and pneumatic actuators. Electrical actuators are available in on-off and rotary modular types, while pneumatic actuators are available in double-acting and spring return configurations. The document provides specific models and configurations for each actuator type.

Additional Information:
For ordering valves with new generation modulating actuators, configuration is necessary as per section A3 of the document.
