Warning!
Spring tension in the valve
Danger of injury when opening the clamp connections at the actuator (46) or
at the housing (43) as the released spring pretension will suddenly lift the
actuator.
► Therefore, release the spring tension before detaching the clamp
connections by pressurizing the actuator with compressed air at max. 8 bar.
Notice
The valve disk, the bearing disk and the sealing washer are
sensitive parts.
Damage to these parts can result in malfunction.
► When the shaft of the valve disc is pulled out, the stem of the valve disc
must not hit the valve housing!
► The bearing disk and the sealing washer must not hit the stem of the
valve disk when the valve insert is withdrawn.
► Do not set the valve insert down on the valve disk but lay it down.
Carry out the following steps:
1.
Release three cheese head screws (25) and take off the cap (B1).
2.
Pressurize the actuator with compressed air, max. 8 bar, by activating
solenoid valve (Y1 at the manual operation element (S).
®
The valve disk (15, 17) is raised.
