Possible control units are: Positioner Type 8692, 8694 and 8696 • For neutral gases and liquids up to 25 bar. Process controller Type 8693 • Vapour up to 230 °C for steel valve seat seal (see chapter „7.4.1“). Vapour up to 130 °C for PTFE valve seat seal. Structure Hot water up to 200 °C for steel valve seat seal The angle-seat control valve consists of a pneumatically operated (see chapter „7.4.1“). piston actuator, a control cone and a 2/2-way angle-seat valve body. • Aggressive media. The control cone is modularly connected to the actuator spindle via a spring-type straight pin, and can thus be quickly replaced. Nearly all line connections are possible for the body. Bushing and welded connection are offered as the standard device. 5.4.1 Application areas The valve seats are directly integrated. The flow direction is always e.g.

Because the medium pressure is below the control cone, it helps open the valve. WARNING! Valve leak if there is too little minimum pilot pressure or high medium pressure! Minimum pilot pressure for CFB and CFI that is too low, or failing to meet the permitted medium pressure, can cause a leak in the valve seat. ▶ Adhere to minimum pilot pressure. ▶ Do not exceed the medium pressure.
