Product catalog summary

Technical Specifications:
The Double Flanged Butterfly Valve F012-A is designed for high-pressure applications up to 25 bar. It features a vulcanized liner and a through-going shaft, allowing installation in any position without maintenance. Suitable for offshore, water and wastewater technology, power plants, desalination, trunk mains, pipelines, and pumping stations.

Key Features:

Triple shaft bearings and single flange mounting.
Adjustable bearings ensure tightness under maximum pressure loads.
Nominal diameter ranges from DN 50 to DN 1400.
Temperature range: -40°C to +200°C, depending on pressure, medium, and material.
Operating pressure: max. 25 bar; Differential pressure: max. ∆p 25 bar.
Vacuum capability up to 1 mbar absolute.

Performance Parameters:

Kv-values indicate the flow of water at temperatures between 5°C to 30°C at a ∆p of 1 bar.
Maximum permissible flow velocity: 4.5 m/s for liquids and 70 m/s for gases.
Throttle function is linear between 30° to 70° angles.
Avoid cavitation for optimal performance.

Torque and Material Specifications:

Initial breakaway torques are provided for liquids and lubricant media, with adjustments for powdery and dry gases/high viscous media.
Material specifications include nodular cast iron, stainless steel, and various rubber compounds for different parts of the valve.

Dimensional Data:
Detailed dimensional data for various sizes of the valve, including flange accommodations and weight specifications.

Applications and Standards:

Complies with standards such as EN 558, ISO 5752, ASME B16.5/B16.47, and others.
Marking and tightness checks conform to EN 19 and EN 12266 standards respectively.

Performance Data:
Includes tables showing opening angles and corresponding torque values for different nominal diameters (DN) and sizes (inches), along with operating pressure data for various disc pressures ranging from 3 bar to 25 bar.

Additional Notes:
Initial breakaway torques are provided for different media, with adjustments for powdery (non-lubricant) media and dry gases/high viscous media. These values are approximate and depend on factors such as pressure, medium, rubber quality, and temperature. Engineers are available to provide exact values for specific applications.
