18.4.11 Single seat - Two-way-valve Typ: 571456. Installation informations6.1 Installations instructionsPreferably install the two way change-over valve vertically. Install the connection lines in such a wayas to permit the liquids to drain freely out of the housing.Valves with welded ends that serve as connecting members can be directly welded to the piping.6.2 Welding guidlinesSealing elements integrated in weld components must generally be removed prior to welding.To prevent damage, welding should be undertaken by certified personnel (EN287). Use the TIG (Tung-sten Inert Gas) welding process.7. Maintenance7.1 MaintenanceThe maintenance intervals depend on the operating conditions "temperature, temperature-intervals,medium, cleaning medium, pressure and opening frequency". It is recommended to change theleakage butterfly valve-seal annually. The maintenance intervals, however, depend on the condition ofthe seals and are to be fixed by the user.6 ActuatorThe actutator is maintenance-free and non-removable.7.2 CleaningCleaning of the upper and lower valve chabers is performed with the pipe cleaning system.8. Control system - and interrrogation system8.1 Control head - optional-Optionally, modular valve control systems can be installed to the actuator for reading and actuatingvalve positions. The standard version is a closed system with twofold limit position messaging (stan-dard), with SPS, Interbus or ASI bus switch-on electronics, and integrated 3/2-way solenoid valves. Fortough operating conditions we recommend employing a stainless steel hood.8.2 Proximity switch mounting set -optional-For the acquisition of the valve positions over inductive initiators, a limit switch support is mounted onthe actuation. The enquiry takes place over the position of the piston rod. NOTEIf installed horizontally, some minor residual liquids will remain in the ball-shape of the housing. NOTEImpurities can cause damage to the seals and seals area. Clean inside areas prior to assembly.
