Large door L-VAT

Product catalog summary

Main Applications: The document outlines the use of the Series 07.8 doors with pneumatic actuators in FPD (Flat Panel Display) and PV (Photovoltaic) production systems.

Ordering Information: The doors are available in various opening sizes ranging from 81 × 800 mm to 250 × 3000 mm. Specific ordering numbers are provided upon request.

Technical Data:

Leak Rate: The gate in the closing direction has a leak rate of less than 1 · 10^-7 mbar Is^-1 with a differential pressure of 1 bar.
Differential Pressure: In the closing direction, it is ≤ 1 bar, and in the opening direction, it is ≤ 5 mbar.
Service Life: The system can perform up to 1 million cycles until the first service, which is reduced to 0.5 million cycles if the actuator is mounted laterally.
Temperature Limits: The gate can withstand temperatures up to 120 °C for aluminum and 150 °C for stainless steel, while the actuator and position indicator can handle up to 80 °C.
Materials: The gate is made from aluminum EN AW-5083 or stainless steel AISI 304/316L. Actuator shafts are hard-chrome plated AISI 304, and connecting parts are EN AW-6082.
Seals: The gate and actuator use FKM (Viton®) and NBR for sealing.
Mounting Position: The actuator can be mounted up, down, or laterally.
Position Indicator: Operates at 10 – 30 V DC with PNP (NPN optional).

Functional Principle: The system uses a solenoid for impulse actuation at 24 V DC, with options for other voltages and surface treatments like hard anodizing or nickel plating.

Features: The document highlights the use of L-VAT sealing technology, low particle and vibration emissions, and low ownership costs.
