Product catalog summary

Main Features
The Fast Closing Valve, Series 75.0 / 75.2, is designed for high reliability and maintenance-free operation. It is part of a field-proven system and is available in sizes ranging from DN 40 to 200 mm (1½" to 8"). The valve features pneumatic actuators that are double-acting, with a body made of stainless steel and standard CF-F flanges. The valve is equipped with a bellows feedthrough.

Functional Principle
The Series 75.0 flap valve and 75.2 gate valve are used to maintain vacuum in accelerators and storage rings in the event of an air inrush.

Technical Data
The valve body has a leak rate of less than 1 · 10^-10 mbar ls^-1, and the valve seat has a leak rate of less than 1 · 10^-9 mbar ls^-1. It operates within a pressure range of 1 · 10^-10 mbar to 2 bar (abs) and can withstand a bake-out temperature of up to 200°C for the valve body and 50°C for the actuator. The valve body is radiation resistant up to 108 Gy.

Materials
The valve body for DN 40 is made of AISI 304, while DN 63 – 200 is made of AISI 316L. The gate/plate for the 75.0 flap valve is titanium, and for the 75.2 gate valve, it is AISI 304. The bellows are made of AISI 316L.

Ordering Information
Standard valves and valves with options can be ordered using specific ordering numbers. Spare parts are available upon request, and customer-specified flanges can be provided. Accessories include flange connections and controllers.

Main Dimensions
The document provides detailed dimensions for both the 75.2 gate valve with pneumatic actuator (DN 40) and the 75.0 flap valve with pneumatic actuator (DN 63 – 200). These dimensions include various measurements in millimeters and inches for installation and maintenance purposes.
