This manual provides essential guidance for the installation, operation, and maintenance of Bardiani Valvole's mixproof valves. It is crucial for qualified technicians to review this document before handling the valves. The manual is updated regularly, with the latest version available on the manufacturer's website.
Various warning signs indicate potential hazards such as hand crushing, heavy loads, severe burns, and explosion risks. Mandatory signs include the use of protective gloves, hard hats, safety footwear, and suitable clothing. Maintenance operations should only be performed by skilled personnel.
The valves are designed exclusively for moving fluids and should not be used for other purposes or with unspecified fluids and pressures. They are not suitable for explosive or fire-risk environments unless certified for such use.
The valves have a maximum pressure of PN10 and are made from AISI 316L material. They are compatible with gasket materials like EPDM, FKM, and HNBR and comply with the PED 2014/68/EU directive.
Upon receipt, check the valve for transport damage and ensure it matches the order. Specific lifting methods are outlined for weights up to 25 kg, between 25 kg and 50 kg, and over 50 kg.
Installation should be performed by expert personnel, ensuring correct air pressure and power supply. Minimize stress from vibrations and thermal expansion, follow proper flow direction, and ensure adequate space for maintenance and correct valve orientation.
Before operation, inspect the valve by supplying air to the actuator and powering the valve. Open and close the valve several times to ensure proper functioning.
Common issues include external leaks due to worn gaskets or excessive pressure. Solutions involve replacing seals or using different elastomers.
Regular cleaning is necessary to maintain valve performance, following specific procedures for different components.
Dispose of the valve and its components in compliance with local regulations.
Maintenance includes general and scheduled tasks, requiring specific tools for disassembly and reassembly. Detailed procedures are provided for different valve models.
Includes 2D diagrams of various valve models and warranty information.
Issues such as too many active commands, difficulty in opening and closing, incorrect elastomer type for gaskets, incorrect actuator positioning, impurities in the actuator, and incorrect valve body positioning are identified. Solutions include replacing gaskets, correctly installing actuators, inspecting and maintaining actuators, and repositioning valve bodies.
Valves must be cleaned by experts using appropriate detergent concentrations and following manufacturer instructions. Protective gear is necessary due to potential burns from hot valves and piping. An internal washing cycle is required after installation or servicing, especially if welding has occurred.
At the end of its service life, the valve must be recycled according to local legislation, considering hazardous residues. Steps include ensuring the line is not in use, emptying and cleaning the line, disconnecting air and power supplies, and removing the valve from the system.
Maintenance should be performed by expert technicians with all utilities disconnected. Precautions include discharging fluid pressure and wearing protective gloves. Scheduled maintenance involves replacing valve and actuator gaskets periodically and checking for leaks. Original spare parts should be used for replacements.
A detailed list of tools and components for disassembly and reassembly of various valve models (B925, B925B, B925V, B925A) is provided, including descriptions and part numbers.
Instructions for adjusting the cam to ensure the sensor switches status correctly during valve operation.
Includes EC Declaration of Conformity and 2D diagrams for different valve models, ensuring compliance with relevant EC directives and standards.
Products are manufactured in compliance with technical specifications and directives, ensuring validity under specified conditions.
The warranty covers design, construction, and material defects for 12 months from the delivery date. Defects must be reported in writing within 8 days of detection, with supporting documentation. The warranty is limited to repair or replacement of defective products or components.
Elastomers and electrical components are excluded from the warranty. The warranty does not cover defects from buyer-provided designs, improper transportation, installation, use, maintenance, or storage, normal wear and tear, unauthorized repairs, or negligence. Bardiani Valvole S.p.A. is not liable for indirect or consequential damages.
Consultation of the "Instruction, Use and Maintenance Manual" is mandatory before installation, use, and maintenance. Illustrations are indicative and not binding. Buyers must assess product suitability before ordering. Bardiani Valvole S.p.A. reserves the right to update product information without notice.
