The serpentines preserve the pressure gauge, as they avoid water hammering and decrease the temperature of the fluid, therefore they must be installed before the pressure gauge by connecting them to a pressure gauge tap.
To install the coil, use special products to seal the threads, depending on the fluid intercepted and use the key exclusively on the hexagon.
To install the pressure gauge, screw it up to the stop, holding the coil with the hexagon at the top.
Enter the fluid in the line.
MAINTENANCE The valve does not require maintenance.
DISPOSAL For valve operating with hazardous liquids(toxic, corrosive…) , if there is a possibility of residue remaining in the valve, take due safety precaution and carry out required cleaning operation. Personnel in charge must be trained and equipped with appropriate protection devices.
Prior to disposal, disassemble the valve and separate the component according to various materials. Please refer to product literature for more information. Forward sorted material to recycling (e.g. metallic materials) or dispose it, according to local and currently valid legislation taking into consideration the environment.
Performance data, including pressure – temperature ratings have been developed from published standards, supplier material certifications, design calculations and in-house testing. They cover typical applications and are provided as a general guideline.
