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.
