Robinets à Membrane
This document provides a comprehensive overview of the manufacturing program for diaphragm valves, detailing specifications, pressure ratings, construction materials, and customization options for both flanged and threaded types.
The valves are designed in accordance with EN 13397 standards and tested as per EN 12266-1. Flanges can be customized to meet ASME, BS, DIN, or JIS standards. Pressure ratings vary by valve type and size, with weir type valves ranging from 16 bar for DN 15 to 50, and 6 bar for DN 250 to 350. Straight through types have a maximum rating of 10 bar for DN 15 to 100.
Materials include cast iron, S.G. iron, steel, and stainless steel for the body, bonnet, and compressor. PFA lined valves are made from ductile iron, with lining options such as ebonite, natural rubber, and PFA. Diaphragms are available in natural rubber, IIR, CR, EPDM, nitrile, or PTFE.
Threaded valves can connect according to BS: 21 (BSP or gaz) or NPT standards. Socket weld and butt weld ends are available, adhering to ASME standards.
Valves can be customized with features like pad-locks, chainwheels, travel stop arrangements, extended stems, and both electrical and pneumatic actuators.
The document also discusses weir type valves with alloy steel bodies and provides weight and dimension details for various DN sizes.
Tables include dimensions and weights for different valve types and sizes, along with test pressures for hydraulic and air tests, essential for selecting the appropriate valve for specific applications.
The document highlights the technical specifications and applications for TECOFI diaphragm valves, emphasizing their suitability for the food and pharmaceutical industries due to stainless steel construction and PTFE membranes. It also covers pneumatic actuators and various diaphragm materials.
- Material and Construction: Valves are made from stainless steel with external finishes like vacuublast or satin, and internal finishes including vacuublast, satin, or mirror. The PTFE diaphragm is backed by an elastomer for elasticity.
- Connection Types: Available connections include IDF, SMS, Tri-Clamp, and ISO.
- Self-Draining System: Valves are self-draining when mounted vertically; for horizontal installations, a 15 to 30-degree angle is recommended for optimal drainage.
- Head Loss and Flow Rates: Graphs and tables provide data on head losses and flow rates for various valve sizes and configurations.
- Pressure and Temperature Ratings: Charts outline pressure and temperature limits for different diaphragm materials, including natural rubber, neoprene, butyl, and PTFE.
- Design Features: Actuators are available for valve sizes DN 15 to DN 250, featuring a failsafe spring, corrosion-resistant coating, and emergency handwheel.
- Options and Accessories: Additional options include positioners, limit switches, solenoid valves, and quick exhaust valves for enhanced control and functionality.
- Material Properties: Lists various diaphragm materials, their applications, temperature ranges, hardness, and color coding. Materials include natural rubber, neoprene, butyl, nitrile, hypalon, ethylene propylene, viton, silicone, and PTFE.
- Application Suitability: Each material is suited for specific applications, such as resistance to acids, abrasion, high temperatures, or suitability for food and pharmaceutical use.
