Kv Values: Kv values, which indicate the flow rate through a valve, depend on diaphragm size and material. They are determined according to DIN EN 60534 standards with specific inlet and differential pressures. Variations in diaphragm material and usage can affect these values.

Product Conformity: The valves comply with several regulations, including the Pressure Equipment Directive 2014/68/EU, and are suitable for food and drinking water applications, meeting standards like FDA and USP Class VI. They also adhere to the German Clean Air Act (TA Luft) for leak rate compliance.

Mechanical Data: The document lists weights for different actuator types and diaphragm sizes, with weights provided in kilograms. Installation position is flexible, but optimal draining requires attention to the angle of rotation.

Dimensions: Detailed dimensions are provided for various connection types, including spigot, threaded socket, and flange connections. These dimensions are crucial for ensuring proper fit and function in different piping systems.

Installation and Configuration: The valves can be installed in various positions, but specific configurations and connection types are detailed for optimal performance. The document includes codes for different connection types and materials used in valve construction.

Specifications:

Connection Types: The document outlines two main connection types: Code E4 and E5 for grooved and notched clamps respectively, suitable for pipes DIN 11866 series B and EN ISO 1127.
Material Codes: Material code F4 is applicable up to MG 50, while from MG 80, material code 44 is used.

Specific measurements include face-to-face dimensions (FTF) according to EN 558 series 7.

Connection Type Codes:

Code E7: Aseptic grooved clamp DIN 11864-NKS, suitable for pipe DIN 11866 series C/ASME BPE.
Code E8: Aseptic notched clamp DIN 11864-BKS, also for pipe DIN 11866 series C/ASME BPE.

Material Information:

Code 40: Refers to a forged body made from 1.4435 (F316L) material.

Additional Information: The document includes contact information for GEMÜ Gebr. Müller Apparatebau GmbH & Co. KG, located in Kupferzell, Germany.

Product description GEMÜ Conexo The interaction of valve components that are equipped with RFID chips and an associated IT infrastructure actively increase process reliability. Thanks to serialization, every valve and every relevant valve component such as the body, actuator or diaphragm, and even automation components, can be clearly traced and read using the CONEXO pen RFID reader. The CONEXO app, which can be installed on mobile devices, not only facilitates and improves the "installation qualification" process, but also makes the maintenance process much more transparent and easier to document....
