Product catalog summary

Overview: The document provides technical specifications and ordering information for the UHV angle valve Series 28 by VAT Vakuumventile AG. It includes details on manual and pneumatic actuators, sealing materials, technical data, and options for customization.

Specifications:

Outgassing Rate: Extremely low, suitable for most corrosive gases.
Actuators: Available in manual (removable handwheel) and pneumatic (single acting with closing spring, normally closed) versions.
Body Material: Stainless steel.
Sealing Materials: Plate made of FKM (VITON), bonnet made of metal.
Leak Rate: Body < 5 · 10^-10 mbar l/s, Valve seat < 1 · 10^-9 mbar l/s.
Pressure Range: 1 · 10^-10 mbar to 5 bar (abs).
Temperature Limits: Valve body ≤ 200°C open / ≤ 150°C closed, Manual actuator ≤ 120°C (without handwheel 200°C), Pneumatic actuator ≤ 120°C (option: 150°C).
Material: Valve body AISI 304, Plate and Bellows AISI 316L.

Ordering Information:

Manual actuator ordering numbers: DN 16 (28424-GE01), DN 40 (28432-GE01), DN 63 (28436-GE01).
Pneumatic actuator options include configurations with or without position indicators and solenoids, requiring specification of control voltage.

Technical Data:

Cycle Life: 3 million cycles at Tmax 80°C.
Mounting Position: Any.
Solenoid Voltage: 24 V DC, with other options available.
Position Indicator: Voltage ≤ 50 V AC/DC, Current ≤ 0.1 A, Power max. 1 W.

Options:

Solenoid and position indicator configurations for various temperatures and voltages.
Customizable flanges and sealing materials.

Dimensions: Detailed dimensions provided for valves with manual and pneumatic actuators across different DN sizes (16, 40, 63).
