A Four Way Sealed Gravity Diverter is a high-performance,heavy-duty flow control valve designed exclusively for zero-pressure gravity conveying systems.Also known as a four-way gravity diverter valve,it features one top inlet and four independent outlet chutes,specialized in accurately switching and distributing free-falling bulk materials—including powders,granules,pellets,and small lumps—among four different pipelines,storage bins,or processing equipment.Its integrated sealed structure eliminates dust leakage,material cross-contamination,and residue accumulation,making it an essential component in high-demand bulk material handling lines.

Working Principle

Operated by pneumatic,electric,or manual actuators,the diverter’s internal precision sealing blade(flap)rotates and locks into position to control material flow.Bulk materials enter the valve from the single upper inlet through natural gravity(no air pressure assistance required).The adjustable internal baffle precisely closes three of the four outlet channels at a time,opening only the designated one to direct materials to the target pipeline or equipment.The fully sealed design ensures complete isolation between each channel and the external atmosphere during switching,maintaining airtightness throughout the entire diversion process and preventing material loss or environmental pollution.

Key Features

-Superior Sealing Performance:Equipped with wear-resistant live-loaded shaft seals and high-performance sealing gaskets(UHMW-PE,polyurethane,silicone rubber,or Viton),achieving positive sealing between channels and against the external environment.Effectively prevents fine powder leakage,cross-flow contamination between outlets,and external air intrusion,with no material seepage at closed ports.

-Unobstructed Gravity Flow Design:The valve body has no internal dead corners,cavities,or residual ledges.The smooth,polished inner wall minimizes material buildup,wedging,and clogging,ensuring unimpeded free fall of bulk materials and stable conveying efficiency.

-Abrasion-Resistant Structure:Adopts a recessed blade design that shields sealing edges and flap surfaces from direct impact and abrasion by hard granular materials,significantly extending the service life of vulnerable components and reducing maintenance frequency.

-Precise Four-Way Diversion Control:Supports independent switching between four outlets with accurate positioning.Optional limit switches provide real-time position feedback and interlock control with the production line,avoiding misdirection.Standard diversion angle:0°/22.5°/22.5°/22.5°,with custom angles available to adapt to different pipeline layouts.

-Easy Maintenance&Installation:Equipped with removable side access doors for internal inspection,cleaning,seal replacement,and component overhaul—no need to disassemble the entire pipeline.The compact,integral structure occupies little space and is easy to connect with existing gravity conveying systems.

-Diversified Actuation Options:Available in pneumatic cylinder drive(for automatic control),electric motor drive(for precise positioning),and manual hand lever operation(for small-scale or emergency use),matching various automatic and manual production requirements.

-Versatile Material&Flange Compatibility:Valve body materials include carbon steel(Q235),304 stainless steel,and 316L stainless steel(for food-grade or corrosive materials).Flanges are available in round,square,or rectangular shapes,compatible with ANSI,DIN,JIS,and custom flange standards to meet global market needs.
