The new generation of integrated positioners for combination with actuators from the process valve series Type 23xx/2103 is specially designed for the requirements of hygienic process environments. The operation and selection of the software functions close tight function, inversion of the operating direction of the setpoint signal, characteristic curves selection and switching manual/automatic operation are effected via push-buttons and DIP switches or via the PC interface. The position setpoint is set using the standard signal 4 - 20 mA. In
addition, the enable can be controlled via the binary input and an optional position feedback can be integrated.   The positioner, Type 8694, registers the valve position without
The Type 2731 can be actuated by the 8635 SideControl, SideControls 8792/93 Remote versions or the 8694/8692/8693 TopControl forming a mechanical and functional unit and thus offering a complete control valve system. Using this control valve, continuous regulation tasks for fl uids can be solved.
 deterioration through a contact-free analogue position sensor. Single-acting or double-acting actuators are controlled via the integral positioner system. An AS-Interface communication interface is available as an option. Main customer benefi ts: • Compact design of the valve system with integrated positioner  meets the demands for plant washdown environments through the  selection of materials, external seals and integrated control air  supply to the actuator • Automatic parameterisation of the process controller using the  Process TUNE function • Field bus communication via optional AS-Interface • Air intake fi lter enhances the process valve system availability • Simple and reliable actuator adaption allowing additional actuators  of the process valve series, Type 20xx or actuators from other  manufacturers to be used • Explosion-proof models for zone 2/22
The diaphragm control valve Type 2731 consists of a pneumatically operated piston actuator, a diaphragm and a valve body made of investment cast stainless steel.
The actuator has been designed so that the stroke can be continuously changed. This makes a favourable characteristic possible for the continuous change of the fl ow.
