3 Way Sealed Gravity Diverter is a heavy-duty sealed bulk material flow control valve,also named three-way gravity diverter valve.It is specially designed for zero-pressure gravity flow conveying systems,featuring one top inlet and three independent outlet chutes.It accurately switches and distributes free-falling powdery,granular and pellet bulk materials among three different pipelines,bins or equipment,with excellent airtight sealing performance to eliminate dust leakage,material cross-contamination and residue accumulation.

Working Principle

Driven by pneumatic,electric or manual actuator,the internal sealing flap/blade mechanism inside the valve body rotates and positions precisely.

Bulk materials enter from the single upper inlet under natural gravity without air pressure assistance.The adjustable internal baffle blocks two channels and opens one designated outlet at a time,realizing independent flow diversion to any of the three lower discharge ports.

The fully sealed structural design isolates each flow channel completely during switching,achieving positive sealing between passages and against external atmosphere throughout the whole diverting process.

Key Features

Superior Full Sealing Performance

Adopts wear-resistant live-loaded shaft seals and high-performance polymer sealing gaskets(UHMW,polyurethane,silicone rubber).Effectively prevents fine powder leakage,cross-flow contamination between channels and external air intrusion;no material seepage at closed ports.

Unobstructed Gravity Flow Structure

No internal dead corners,cavities or residual ledges inside the valve body.Smooth inner wall minimizes material buildup,wedging and clogging,ensuring unimpeded free fall of bulk materials.

Protected Abrasion-Resistant Components

Recessed blade design shields sealing edges and flap surfaces from direct abrasion by hard granular materials,greatly extending service life of vulnerable parts.

Flexible&Stable Diversion Control

Precise three-way independent switching;optional limit switches for real-time position feedback and interlock control.Standard diversion angle:0°/30°/30°,custom angles available for pipeline layout adaptation.

Convenient Maintenance Design

Equipped with removable side access doors for internal inspection,cleaning,seal replacement and component overhaul without overall pipeline disassembly.

Diversified Actuation Options

Supports pneumatic cylinder drive,electric motor drive and manual hand lever operation to match different automatic production control requirements.
