SIMPLEX CAST STRAINER HOUSINGS
RF Flanged Ends
Connection sizes 2 to 12 inches
These ANSI 150 class strainers have flanged (RF) end connections, with inlet / outlet connection sizes available from 2 to 12 inches.
The KW series, simplex cast basket strainer, with its large body and sizeable basket, can store large amounts of debris which increases the time between servicing. It also features a machined seat with o- ring that enables filtration, down to 40 microns.
Typical applications include: petroleum, oil and gas, water and wastewater, pulp and paper, chemical and petrochemical, transportation, marine, and food industries.
These KW series ANSI 150 strainers are ideal for many industrial and petrochemical filter applications that have higher pressure and temperature requirements.
