032F6225 032F803432 EVRA 25 Danfoss Type Servo-Piston Operated Flange Solenoid Valve For Ammonia
Product overview of 032F6225 032F803432 EVRA 25 Danfoss Type Servo-Piston Operated Flange Solenoid Valve For Ammonia:
The EVRA 25 Danfoss 032F6225 ammonia solenoid valve is used for automated opening and closing in ammonia network in both liquid and
gaseous phases. The EVRA valve is sold dismembered with body + flange set + coil supplied. In addition to this convenience, repairs are sold
separately. Thus, the valve can be repaired in the pipeline without removal, giving more agility and reliability to the process.

Instructions to the Welder
1. Always use TIG / Argon welding as the root run, to avoid slag and debris entering the valve house.
2. Complete the welding process according to local legal requirements.
3. Inspect the inside around the welding and remove all debris.
Instructions to the Installer
1. Clean the pipes and valve houses with dry air (no water, no sandblasting).
2. Lubricate valve housing sealing surfaces (e.g. with refrigerant oil).
3. Follow the valve installation instructions.
4. Pressure test the system with dry air or inert gas (no water).
Instructions to the Supervisor
1. Build up the system in sections. For example, have valve trains or valve stations pre-manufactured before being shipped on site, or make it in a separate clean workshop on site, where welding and cleaning procedures can be easily controlled.
2. Evacuate the sections to verify that there is no water left in the system.
3. Seal and pressurize finished sections slightly with inert gas.
4. Evacuate down to 5-10 mbar before charging refrigerant.
5. Run free and clean filters frequently for 24-48 hours.
