The accessories of forged steel filters can be adapted to various components according to different usage scenarios. This article introduces its accessories and functions in detail.
1. Main structure components ‌ ‌ Valve body ‌: Forged with carbon steel (A105), stainless steel (A182F304/L) or alloy steel (A182F22), it provides fluid channels and carries internal pressure. ‌ Valve cover ‌: Connected to the valve body by bolts, the material matches the valve body, and is easy to disassemble for maintenance or replacement of the filter ‌. ‌ Valve flap ‌: Some models are equipped with alloy valve flaps (such as A276420, A276304) to adjust or block the flow of the medium ‌. ‌

2. Filter function accessories ‌ ‌ Filter screen ‌: ‌ Material: stainless steel 304/316L, Hastelloy, etc., corrosion-resistant and suitable for high temperature and high pressure environments ‌; Specifications: water mesh 18~30 mesh, oil mesh 100~480 mesh, ventilation mesh 10~100 mesh ‌. ‌Discharge blockage‌: Some models are equipped with a removable discharge port to facilitate cleaning of impurities or replacement of filters‌.
3. Seals and connectors‌ ‌Sealing gasket/ring‌:
Wound gasket (304+flexible graphite) or metal ring to ensure the sealing of the valve body and the valve cover‌; O-rings are used to prevent leakage at flanges or threaded connections‌.
‌Connectors‌: Flange‌: Complies with ANSI B16.5 and JB79 standards, suitable for different pipeline pressures (PN16-PN400); Threaded joints‌: Socket welding or NPT thread (ANSI B1.20.1 standard), suitable for high-pressure scenarios‌.
‌4. Special scene adaptation accessories‌ ‌Insulation layer‌: Ceramic fiber can be used to wrap the valve body in high temperature environments (＞80℃) to prevent heat loss or deformation‌.
‌Anti-loosening bolts‌: It is recommended to use 316L stainless steel bolts in a vibrating environment, and use elastic brackets to reduce the risk of loosening‌.
The selection of accessories needs to be comprehensively matched according to the medium (water/oil/gas), pressure (up to 40MPa) and temperature (-20℃~450℃).
