SERIES B2.3

Product catalog summary

Specifications:
The flanged bronze ball valves of series B2.3 comply with Directive 2014/68/UE and adhere to various design and testing standards, including EN 1092, ISO 7005, ANSI B16.5 #150, EN 1983, EN12516, ISO 5211, EN19, and EN 12266 cat. A. They are made from bronze with a floating ball and are manufactured under ISO 9001 quality management.

Product Variants:
Variants include B2 (full bore with EN 558-1 dimensions), R2 (reduced bore with ANSI B16.10#150 short pattern), and S2 (full bore with ANSI B16.10#150 short pattern).

Applications:
These valves are suitable for naval, offshore, marine environments, HVAC, district heating, water treatment and distribution, industrial, chemical, agricultural applications, compressed air, oils, and hydrocarbons. They are not suitable for steam or flow regulation.

Features:
Key features include an integrated ISO 5211 flange for actuator installation, a dynamic seal with double O-ring, a blow-out proof stem with optional antistatic device, and a PTFE reinforced ball seat.

Accessories:
Available accessories include a thermal insulation stem extension, a square cap for water main connection, a lockable operation lever kit, and limit switches for ON/OFF position indication.

Actuators:
Options include pneumatic actuators (double and single acting), electric actuators, manual gearboxes, and chain-driven gearboxes.

Materials and Temperature Range:
The body is made of bronze, with the ball and stem available in AISI 316, brass, or aluminium-bronze. The O-ring is made of FKM, and the temperature range is -10 to +150°C.

Dimensions and Weights:
Detailed dimensions and weights are provided for various DN sizes, with specific flange dimensions according to EN 1092 PN16 and ANSI B16.5#150 standards.

Operating Torque:
Operating torque values are provided, with a recommendation to multiply by a safety coefficient of 1.5 for actuator selection.

Procedures and Recommendations:
For optimal actuator selection, multiply the operating torque by a safety coefficient of 1.5. The pressure-temperature relationship indicates that maximum working pressure decreases as temperature increases.

Standards and Norms:
The valves comply with standards such as PED 2014/68/EU and 1272/2008 (CLP) for hazardous gases and liquids, with specified maximum pressure ratings for different fluids and mounting conditions.

Performance Data:
Kv values for different DN sizes indicate the flow capacity of the valves. A pressure/temperature chart shows operational limits and advises against use in steam conditions below the liquid-steam saturation line.

Limitations:
The valves are not suitable for steam applications and should not be used below the liquid-steam saturation line. Brandoni SpA reserves the right to modify valve characteristics without notice.

Flangia in accordo a ISO 5211 inte- Classe 150 short pattern per tutti i DN . Integrated flange, in accordance with Face to face, in accordance with EN558/1 or ANSI B 16.10 class 150 short pattern for all DN (diameters). Sfilando una piastrina e ruotandola di 90° è possibile bloccare la leva in posizione aperta o chiusa. Removing and repositioning of the plate at 90° allows locking of the lever in ON-OFF position. Il doppio O-Ring sullo stelo e la bussola metallica garantiscono la tenuta dinamica anche nelle condizioni più gravose. The dynamic seal of the stem is guaranteed by a double O-ring,...
