possible only in combination with a control unit.

6.1 structure
The angle-seat control valve consists of a pneumatically operated
piston actuator, a control cone and a 2/2-way angle-seat body.
Via a dowel pin, the control cone is modularly coupled to the
actuator spindle for quick changeovers.
For the body, almost any line connections are possible.
A threaded port and a welded end are offered as a standard version.
The valve seats are incorporated directly. The flow inlet is always
under seat.
The description of the control function (CF) can be found in
chapter entitled “6.2.1 Control functions (CF)”
