Angle valve with soft-pump function

Product catalog summary

Overview: The document provides technical specifications and ordering information for the Series 29 angle valve with a soft-pump function, manufactured by VAT Vakuumventile AG. These valves are designed to reduce turbulence during initial pump down, resulting in a low particle count.

Specifications:

Body Material: Available in aluminum or stainless steel.
Pneumatic Actuator: Single acting with a closing spring (normally closed), without position indicator or solenoid.
Sealing Materials: VITON for both plate and bonnet.
Leak Rate: Less than 1 x 10^-9 mbar l/s.
Pressure Range: 1 x 10^-8 mbar to 1.2 bar (absolute).
Temperature Limits: Body up to 150°C, pneumatic actuator up to 120°C, position indicator up to 80°C (optionally 120°C), solenoid up to 80°C.
Material Details: Aluminum body (AlMgSi1) and stainless steel body (AISI 304), with plate and bellows made from AISI 316L.

Technical Data:

Cycle Life: 2 million cycles at Tmax 80°C.
Mounting Position: Any.
Solenoid Voltage: 24 V DC, 2.5 W (other options available).
Position Indicator: Voltage ≤ 50 V AC/DC, Current ≤ 0.1 A, Power ≤ 1 W.

Ordering Information:

Valves are available in different configurations based on the presence of position indicators and solenoids. Specific ordering numbers are provided for each configuration and size.
Options include solenoids for various voltages, position indicators for higher temperatures, and different sealing materials.

Dimensions and Weights: Detailed dimensions and weights are provided for different valve sizes (DN 25, 40, 50) in both aluminum and stainless steel versions.

Additional Features:

Adjustable soft-pump opening to minimize turbulence.
Bellows feedthrough at the main valve and shaft feedthrough at the soft-pump valve.
