Flanged ball valves - corrosion resistant
Flanged ball valves - corrosion resistant
SAFI, founded in 1963, specializes in manufacturing corrosion-resistant thermoplastic valves designed for handling corrosive and abrasive chemicals. Their products focus on cost efficiency, technical demands, and compliance with modern industry regulations and standards.
SAFI offers a variety of valves, including flanged ball valves, which are robust and reliable for use with corrosive chemicals. These valves serve as a superior alternative to lined steel diaphragm valves in certain applications.
SAFI valves are made from materials such as Glass Reinforced Polypropylene (GRPP), Anti-static Polypropylene, and Polyvinylidene Fluoride (PVDF), providing high mechanical strength, chemical resistance, and stability under various conditions.
The manufacturing process includes symmetrical injection molding to prevent distortion and weaknesses. Components undergo heat treatment and machining for dimensional stability, ensuring high-quality sealing surfaces.
SAFI valves include PTFE thrust bearing washers for reduced torque, fully encapsulated steel-reinforced flanges, and compression-molded seats for improved sealing, enhancing durability and performance.
SAFI valves are used in industries such as chemical processing, water treatment, and agriculture, particularly effective in applications involving sulfuric acid and environments with erosion and abrasion challenges.
SAFI valves are available in sizes from DN15 to DN150, complying with standards like TA-Luft and ISO 15848, designed to handle a wide range of chemicals and conditions, providing reliable performance over time.
The valves range from DN15 to DN150, with a 6” valve capable of holding 250 kg at the end of a 1m pipe section and breaking at 961 kg. The shell burst pressure test is conducted in bars, indicating outstanding mechanical resistance.
The body materials include PVDF, GRPP, ASPP, and ASPVDF. Components such as the body, flanged end, locking key, O-rings, seat, thrust washer, ball, handle, and stem are specified with their respective materials.
Valves can be equipped with pneumatic or electric actuators. Pneumatic options include kinetrol vane type, rack & pinion, and Max-Air corrosion-resistant thermoplastic actuators. Electric actuators are available for various voltages with corrosion-resistant thermoplastic casing. Manual operation options include lockable handles, extended stems, spring return handles, and handwheel reduction gears.
V-port flow control valves and complete valve and actuator packages are available to meet specific flow requirements while ensuring corrosion and erosion resistance. A ball relief hole is recommended to prevent accidents with decomposing chemicals.
Detailed dimensions and weights are provided for each valve size, along with flow data, recommended temperature and pressure limits, and torques for flanged bolting.
Three-way valves are available up to DN100 with L-Ball, double L, or T-ball configurations. The document also includes a bill of materials and an enquiry form for customer service conditions and valve definitions.
SAFI's contact details are provided for further inquiries or quotations.
SAFI's commitment to quality and innovation ensures that their valves provide effective solutions for handling corrosive fluids, reducing maintenance costs, and enhancing operational safety.

Quality assured integral flanged ball valves SAFI’s integral flanged ball valves form a range of extremely robust and reliable valves for use with corrosive chemicals such as strong acids and alkalies. They offer good alternatives to lined steel diaphragm valves, lined plug valves and lined ball valves. In some services, they outperform valves made of special metals, such as Alloy 20, chromium cast iron, titanium etc... Their resistance to abrasion is good, and they generally perform better in slurries than PTFE lined diaphragm valves. The valves have TA-Luft and ISO 15848 certification. Food...

SOLUTIONS & APPLICATIONS The alternative to stainless steel valves 1) Stainless steels, duplex steels and even high nickel alloys such as Alloy 20 are resistant to acids due to a thin natural invisible «passivation» layer of nickel oxide or halide which occurs at the surface of the metal during the manufacturing process. This natural passivation layer «shields» the metal from chemical attack and protects against corrosion. 2) In common textbooks and chemical resistance charts stainless steel is shown to have resistance to many corrosive chemicals. However often this resistance is conditional...

MANUFACTURING PROCESS How to handle corrosive fluids in explosion hazard areas ? How do you handle acids and other corrosive chemicals in an area classified as «explosion hazard area» where metal valves corrode and ordinary plastic valves are prohibited ? SAFI Flanged Ball Valves are available in corrosion resistant anti-static thermoplastics filled with carbon fibre.The surface resistivity of the materials is less than 109 ohms, as required by the standard EN 50014 and the total resistance between any two points of the valve is less than 106 ohms. The valves qualify for ATEX zones 1 and 2 according...
