Description:
General:
These valves increase the security of the machine operator and extend the machine's service life.
The minimum operating pressure is 2 bar. Maximum operating pressure is 21 bar for the pneumatic
and 10 bar for the electrical valve. Temperature range runs from 0° / 32 °F to 50 °C / 122 °F.

Pneumatic_soft_start_valve:
When connecting the air supply with the valve, the system is slowly filled with compressed air by an
adjustable restrictor. The valve switches over to full scale operation when ca. 60% of the nominal
pressure is reached. The pressure raising period can be set by adjusting the restrictor.
Note; The valve is not suitable for exhausting the system.

Electric_soft_start_valve:
As with the pneumatic soft start valve, the system is slowly filled with compressed air by an adjustable
restrictor. However, switching over to full scale operation is carried out by the electrical switching valve,
which receives the signal by an external pressure switch, for instance.

Electric_3-port/2-way_valve:
The electrically-operated 3-port/2-way valve is normally closed and directly controlled. It is capable of
quickly pressurising and depressurising the system. The valve has a tapped exhaust.

Soft_start_switch-on/off_valve:
By the soft start switch-on/off valve the system is slowly filled with compressed air. Full scale
pressurising or depressurising is achieved by the electric 3-port/2-way valve. The valve has a tapped exhaust.
