Product catalog summary

Design Specifications
The document outlines the design of a double flanged butterfly valve with various end connections including EN 1092, ASME B16.5, MSS SP 44, AWWA C207, and BS 10. The face-to-face dimensions adhere to EN558-1/2 Series 13 and ISO 5752 Series 13. The valve features a non-replaceable body seat and a lining bonded to the body. The shaft seal design includes an O-ring bush, and the driving shaft has an indication for the disc position.

Testing Procedures
The valve undergoes several tests: shell strength and tightness tests according to EN 12266-1, ISO 5208, and API 598; seat tightness test to EN 12266-1, ISO 5208, and API 598 standards; and an operability test as per EN 12266-2, ISO 5208, and API 598.

Options
An anti-static design is available in accordance with EN 736/3 and API 609.

Functional Characteristics
The valve is suitable for on/off, regulating, and control applications. It has a design pressure of up to 16 bar and a temperature range from -20°C to +200°C. The maximum flow velocity is 5 m/s for liquids and 50 m/s for gases. The seat tightness rate is bi-directional, conforming to ISO 5208 rate A.

Marking & Certification
The valve is marked according to EN 19 and MSS SP 25, with certification options including EN 10204 - 2.2, 3.1, and 3.2.

Product Data
The butterfly valve is centric rubber lined, designed according to EN 593, and available in sizes ranging from DN 50 to 1400 (NPS 2” to 56”). The maximum pressure is 10/16 bar, with an optional 20 bar for sizes up to DN 600.

Parts List
The document provides a detailed parts list for two size ranges: EVFS 50-350 (2"-14") and EVFS 400-1000 (16"-40"). Materials for components such as shafts, bushings, O-rings, bodies, bearings, discs, and linings are specified, with options for different materials based on size and application requirements.
