These are used on the pipeline sections where their installation is more suitable than that of axial valves. This type is used for high pressure installations. The housing is made of carbon or stainless steel. Valve ends can be threaded, welded SW, BW or flanged. They are made for pressure grades PN6-PN300bar and in sizes DN15-DN300. Filter fineness depends on the request and can go from 5µm to 25µm (fine filtration) or 25µm -200µm (rough filtration). The sieve is made of stainless steel.
