LUG TYPE BUTTERFLY VALVE Z 614-A

Product catalog summary

Overview: The document provides technical specifications and details for the Lug Type Butterfly Valve Z 614-A, designed for semi-corrosive media. It highlights the valve's torque values, Kv-values, technical data, features, applications, and material specifications.

Torque and Kv-Values:

Initial breakaway torques are provided for liquids and lubricant media, with adjustments for powdery and dry gases/high viscous media.
Kv-values represent the flow of water at 5°C to 30°C with a pressure drop of 1 bar, based on tests by Delfter Hydraulics Laboratories.
Permissible flow velocities are 4.5 m/s for liquids and 70 m/s for gases.
The throttle function is linear between 30° to 70° angles, and cavitation should be avoided.

Technical Data:

Nominal diameter ranges from DN 50 to DN 300.
Face-to-face dimensions comply with EN 558 Series 20, ISO 5752 Series 20, and API 609 Table 1.
Flange accommodation includes EN 1092 PN 10/16 and ASME Class 150.
Temperature range is -10°C to +200°C, with a maximum operating pressure of 10 bar.

Features:

One-piece disc/shaft and split body with stainless steel screws.
Triple shaft bearing and mirror-polished disc sealing surface.
Materials available that comply with FDA standards and options for silicone-free versions.
Design certified to TA-Air/VDI 2440 by RWTÜV.

General Applications:

Suitable for industries such as food and beverage, pharmaceuticals, chemical and petrochemical, water and wastewater, shipbuilding, power plants, and civil engineering.

Material Specifications:

Body made of nodular cast iron, with various rubber options for the seat, and stainless steel for the shaft/disc.
Other materials include brass for bearing bush and copper for seals.

Dimensions and Weights:

Detailed dimensions and weights are provided for each nominal diameter from DN 50 to DN 300.
