Serie B2.1

Product catalog summary
Overview: This document outlines the specifications and standards for Brandoni's Serie B2.1 flanged ductile iron ball valves, suitable for HVAC, water treatment, industrial, and agricultural applications.
Specifications: The valves comply with directive 2014/68/UE and Italian regulation D.M.174 for drinking water. They are designed according to EN 1983, EN12516, and ISO 5211 standards, with 100% testing per EN 12266 cat. A.
Design and Features: Featuring a split-body design with a floating ball, these valves minimize turbulence and head loss. They include a blow-out proof stem, dynamic seal with double O-ring, and high-temperature resistant epoxy coating. Not suitable for steam or flow regulation.
Materials: The body is ductile iron, with ball options in AISI 304, AISI 316, or brass. The stem is available in brass or stainless steel, and the ball seat is carbon-reinforced PTFE.
Accessories: Options include thermal insulation stem extensions, lockable levers, limit switches, and pneumatic/electric actuators.
Dimensions and Weight: Detailed dimensions and weights are provided for valve sizes DN 15 to DN 250, along with operating torque requirements.
Applications: Suitable for in-line and end-of-line installations, supporting frequent operations with a range of actuators due to ISO 5211 support.
Pressure/Temperature Chart: The chart indicates unsuitability for steam, warning against use below the liquid-steam saturation line as maximum pressure decreases with temperature.
Drilling Specifications: Flange drilling specifications are outlined for PN 16 EN1092/2, with options for PN 10, PN 6, PN 25, and ANSI B16.5 #150.
Maximum Pressure: Varies by fluid type and mounting method. Hazardous gases/liquids: 16 bar for DN15-200, 10 bar for DN250. Non-hazardous gases/liquids and water: 16 bar.
Temperature Limits: Continuous temperatures range from -10°C to 100°C, with peak temperatures up to 170°C for materials like NBR and FKM (Viton®).
Head Loss and Kv Values: A table provides Kv values for different DN sizes, indicating flow rate in mc/h for water, with head loss as 1m H2O = 0.098 bar.
Disclaimer: Brandoni SpA may modify valve characteristics without notice; further information is available on their website.
