Product catalog summary

Overview: This document provides technical specifications and ordering information for stainless steel valves with bellows, designed for harsh process conditions. The valves are suitable for a differential pressure opening of 1 bar and feature easy maintenance due to a simple wedge design.

Specifications:

Body Material: Stainless steel
Actuator Types: Manual (handwheel) and pneumatic (double acting)
Sealing Materials: FKM (VITON) for gate and bonnet
Pressure Range: 1 · 10^-9 mbar to 1.2 bar (abs)
Temperature Limits: Valve body up to 120°C (150°C on request), actuators up to 100°C
Leak Rate: Body < 1 · 10^-9 mbar l/s, Valve seat < 1 · 10^-7 mbar l/s
Material: AISI 304 for valve body and gate, AISI 633 for bellows

Ordering Information:

Valves are available in sizes DN 50 to DN 160 (2" to 6")
Ordering numbers vary based on size and connection type (ISO-KF, ISO-F, JIS, ASA-LP, CF-F)
Options include solenoids for various voltages and bake-out jackets

Technical Data:

Bellows Feedthrough: 100,000 cycles
Cycles Until First Service: 5,000 cycles
Mounting Position: Any
Solenoid Voltage: 24 V DC, 5.4 W
Position Indicator: Voltage 10 - 30 V DC, Current ≥ 0.5 A, Power max. 10 W

Dimensions: Detailed dimensions for manual and pneumatic actuators are provided, including flange dimensions for various standards (ISO, JIS, ASA-LP).

Features: The valve design is robust with a wedge sealing system, and it operates without grease or moving parts in the vacuum.
