Strainer

Y Strainer is the filtration equipment which is to prevent impurities in the flow media from flowing into the back-end equipment. The strainer is usually being installed before the Water Control Valves, Pressure Reducing Valves and other equipments sensitive to medium cleanliness in order to prevent particulate impurities entering into the back-end equipment to ensure the normal operation of the back-end equipment. The screen superficial area is 4 times of the relative area, so as to achieve a low flow resistance, which ensures the screen from deformation when the differential pressure in the pipeline is too large. Mesh of the screen can be changed according to customer requirements.

Storage & Maintenance

1. For long-term storage Y Strainer should be placed in a cool dry place, not allow to be stored or stacked in the open air.
2. Installation:

• Check whether the working condition is matched with the strainer pressure, temperature, corrosion resistance or not before installation;
• Attention should be paid that the flow direction of the medium should be in line with the arrow direction on the valve body when installing the strainer;
• Both sides of the flange connections must be parallel and coaxial;
• Check all the fasteners are loose, damaged or not;
• Fasten the flange bolts symmetrically and alternately;
• The daily sewage treatment can be done as long as removing the sewage bolts;
• After long-term use by extracting the sewage cover can do the filter for cleaning and remove the retained impurities on the screen.
