LUG TYPE BUTTERFLY VALVE Z 414-A

Product catalog summary

Technical Specifications:
The document outlines the specifications for the Lug Type Butterfly Valve Z 414-A, suitable for PE/PP piping systems. It supports nominal diameters from DA 50 to DA 630 and DN 40 to DN 600, adhering to SDR11, SDR17, and SDR17.6 standards. The valve is resilient seated, centrically mounted, and operates within a temperature range of -10°C to +160°C, with a maximum pressure of 10 bar. It complies with standards such as EN 558 Series 20, ISO 5752 Series 20, and API 609 Table 1.

Torque and Kv-Values:
Initial breakaway torques are specified for various media, with adjustments for different conditions. Kv-values are derived from tests by Delfter Hydraulics Laboratories, indicating water flow at 5°C to 30°C with a pressure drop of 1 bar. The permissible flow velocity is 4.5 m/s for liquids and 70 m/s for gases, with a linear throttle function between 30° to 70°.

Features:
The valve is designed for the plastic piping industry, offering custom components, clear identification, and easy assembly. It is compatible with PE/PP pressure pipes and fittings, enhancing plant safety by eliminating spacers. The valve is maintenance-free, demountable, and recyclable.

General Applications:
The valve is applicable in water management, agriculture, food industry, energy, environment, mobility, aviation, and drainage systems.

Material Specifications:
The document provides a parts list with materials such as nodular cast iron for the body and stainless steel for the shaft, along with various rubbers for seals and O-rings. Dimensions and weights for different sizes are included.

Overview:
The document details technical specifications for discs under various pressure conditions and opening angles for different pipe diameters, including data for discs at 3 bar, 6 bar, and 10 bar pressures.

Specifications:

Disc Specifications: Lists outer diameter (Ø) and nominal diameter (DN) for discs at pressures of 3 bar, 6 bar, and 10 bar, showing uniform disc thickness across different diameters.
Opening Angles: Provides opening angles for SDR11 and SDR17 pipes at 10 bar pressure, with data from 20° to 90° for various pipe diameters, indicating flow capacity at each angle.

Key Data Points:

For DN 50 mm, disc thickness is consistently 8 mm across all pressure levels.
For DN 500 mm, disc thickness increases significantly, reaching up to 860 mm at 10 bar.
Opening angles for DN 50 mm show a gradual increase in flow capacity from 1 to 55.4 for SDR11 and from 1 to 63 for SDR17 at 90°.
For DN 630 mm, flow capacity at 90° reaches up to 15200 for SDR11, indicating increased capacity with larger diameters.

Conclusions:
The document provides detailed specifications for disc thickness and flow capacity at various pressures and opening angles, highlighting the scalability and efficiency of disc and pipe systems across different sizes and pressure conditions.
