Data Sheet
Angle-seat externally operated valve
Type AV210A - AV210H
For use in industrial applications
AV210 is an externally operated valve for use in
demanding industrial applications.
The valve can operate at very high medium
temperatures and viscosities, and is insensitive
to dirt particles in the medium; thus, it is often
called a “troubleshooter” valve. The valve is
available in bronze and stainless steel.
Features
• For all uids and gases
• Flow range: 0 – 234 m3/h / 0 – 275 USgal/min
• Unpressurized closed (NC) bidirectional
versions and unpressurized opened (NO)
version closing against the ow direction
• The valves can be used for rough vacuum
• Control connection G ⅛
• Valves comply with Pressure Equipment
Directive 97/23/EC
• NC version: bi-directional, closing against or
closing with the ow direction
• NO version: always closing against the ow
direction

2 Functions
2.1 NC ISO / NPT Connection
AV210 unpressurized closed version (NC) bidirectional.
The valve is kept closed by the spring (1), which presses the seat gasket (2) against the valve seat (3). When the
pressure is applied to the control connection (4), the control piston (5), the spindle (6) and thus the seat gasket (2)
are raised, and the valve opens with or against the pressure of the medium.
2.2 NO ISO Connection
AV210 unpressurized open version (NO):
The valve is kept open by the spring (1), which keeps the seat gasket (2) away from the valve seat (3). When pressure
is applied to the control connection (4), the control piston (5), the spindle (6) and thus the seat gasket (2) are
lowered, and the valve closes against the pressure of the medium.
