The presence of foreign particles in an automatic valve may seriously affect its dependability. The installation of a strainer close to the inlet side of valve is the best means of preventing entrance of pipe chips, scale, or sediment into valve, provided the screen is preiodically removed for cleaning. Construction Strainer bodies have screwed ends.
Screens are of stainless steel with opening sizes as listed in table.
Other sizes can be furnished upon request. Liberal straining area provides for fluid passage at minimum pressure drop. Screens are easily removed for cleaning. Strainers are furnished with NTP blowoff connections unplugged. See chart below for blow-off sizes.
