WARNING!
Risk of personal injury.
• Maximum recommended air pressure is 1 MPa (10 bars). A pressure
regulator must be installed if the pressure is likely to exceed the maximum
pressure. Recommended working pressure is 0,6-0,7 MPa (6-7 bars). Min.
pressure for a reliable function is 0.5 MPa (5 bars).
• Compressed air hoses must be approved for the actual pressure and must
be securely fastened to the valve nipples. Hose clips must be fitted correctly.
• The valve is designed for vacuum, ie, it should only be installed in systems
working with negative pressure compared to atmosphere.
Figures 6 - 8 explain how to connect TAV valves having different control
devices. A "flash arrow" indicates an electric supply. P indicates a compressed
air supply.
• TAV 100/150 PC (figure 6) is not fitted with its own control device. It is
intended for direct control with a remote 3-port pilot valve (option).
•
TAV 100/150 MA (figure 7) is controlled by a hand operated lever. It is
used when there is no need for automatic controlling.
•
TAV 100/150 MV (figure 8) has a solenoid valve control device. The
solenoid voltage must match the signal voltage. Standard voltage is 24,
42, 230 V AC and 24 V DC. The power is 5 VA or 5 W.
TAV 100/150 MV can be directly controlled by a stationary electric machine.
However, extra branch fuses should be used if the mains fuses are too large for
this function. See rated voltage and power on the solenoid.

Directions for use

WARNING!
Risk of personal injury.
• Keep fingers clear off the vacuum connections when the valve is connected
to compressed air. The spring that closes the valve is strong enough to cause
discomfort.
• Make sure the system does not transport material which can damage the
TAV valve.
• If an unexpected object comes into the system, shut the compressed air
supply to the valve immediatelly and remove the object.
•
The valve must not be put into service until the valve inlet and outlet are
connected to fixed pipes or hoses that are at least 1 metre long.
