ITEM 545

Product catalog summary

General Features: The carbon steel ball valve, item 545, is a 3-way flat body flanged valve with an 'L' port. It is designed with flanges conforming to EN 1092-1 standards, suitable for PN40 up to DN50 and PN16 for DN65, 50, and 100. The valve operates within a temperature range of -10°C to +150°C, extendable to +200°C with special seals, and is suitable for water, petroleum, and petrochemical products. Reduced bore is a feature, and body material options include A350 LF2 for temperatures down to -20°C. Seals can be made of PTFE with glass or carbon graphite.

Approvals: An ATEX version is available upon request, compliant with directive 2014-34-EU.

Diagrams & Breakaway Torque: The document includes a pressure/temperature diagram and details on breakaway torques for various sizes, indicating that torque can vary with temperature and fluid type. A safety factor of 1.4 is recommended, and torque may decrease with high operation frequency.

Codes and Materials: The document lists valve codes for standard execution and ATEX versions, along with weights for each size. Materials used include AISI 316 and 304 for various components, with PTFE and FKM for seals and O-rings.

Dimensions: Detailed dimensions are provided for sizes ranging from DN15 to DN100, including measurements for various parts of the valve.

Drives: Information on double-acting and spring-return pneumatic actuators is provided, including model numbers, mounting kits, dimensions, and weights. The sizing is based on a minimum air supply pressure of 5.6 barg. Electric actuators are available on request.

N.B. please choose the rest position of the ball when the SR actuator is used, paying attention to the fact that this actuator turns in an anticlockwise direction, whenever supplied with air. Torque can vary depending on temperature and type of fluid; a safety factor of 1.4 must be applied. Torque can drop on high frequency of operations. The actuator/valve sizing,...
