Diaphragm valve T4

Product catalog summary

General Specifications:
The diaphragm valve T4 is constructed from materials such as PVC-U, PP, and PVDF, with seal materials including EPDM, FPM, and PTFE/EPDM. It is available in dimensions ranging from DN15 to DN50, with various connector types like solvent socket, fusion spigot, and backing flange.

Operating Pressure:
The valve operates at a pressure of PN10.

Control Functions:
The valve can be configured as Normally Closed (NC), Normally Open (NO), or Double Acting (DA).

Pneumatic Actuating Drive Features:
The drive is made from PA-GF with a stainless steel control air socket, suitable for neutral gases or air. It can be installed in any position, preferably with the drive facing upwards. Key features include rapid opening and closing, high flow rate, visual position indication, and a NAMUR connector for solenoid valves.

Accessories:
Available accessories include an electrical position indicator, electropneumatic positioner, and solenoid valves with 3/2 and 5/2 functions.

Dimensions and Technical Data:
Detailed dimensions are provided for various connector types and materials, with specific measurements for DN sizes ranging from 15 to 50. The document includes tables and diagrams illustrating pressure loss, Cv values, and pressure-temperature relationships for different materials.

Control Pressure Data:
The document outlines maximum operating pressures for different seal materials and drive sizes, with specific control pressure ranges for NC, NO, and DA functions.

Accessories Specifications:

Electrical Position Indicator: Made from polyamide and polycarbonate, it operates within -10°C to +80°C and supports voltage ranges of 12-24 V AC/DC and 110-250 V AC/DC.
Electropneumatic Positioner: Constructed from aluminum and plastic, it handles air or neutral gases with a pressure range up to 10 bar and operates within 0°C to 60°C for the medium and 0°C to 50°C for the environment.
Solenoid Valve: Features a NAMUR design with 5/2 and 3/2 functions, made from anodized aluminum with NBR seals, supporting voltages of 24 V DC and 230 V AC.
