Two-way Flap Type Diverter Valve

The Two-way Flap Type Diverter Valve is a specialized flow control device designed for bulk material handling systems,dedicated to redirecting dry solids,powders,granules,or slurries from one inlet to two selectable outlets in a two-way flow path.As a core component in material distribution systems,it features a simple yet robust flap structure,ensuring reliable,efficient flow redirection with minimal maintenance,widely applied in various industrial gravity-driven or low-pressure conveying scenarios.

The working principle of this valve is intuitive and efficient:its internal core component is a pivoting flap(vane),which is installed at the junction of the single inlet and two outlets.When activated,the flap rotates 90 degrees or to a preset angle,seamlessly blocking one outlet while fully opening the other,guiding the material flow to the desired direction.Unlike multi-way diverter valves,it focuses on two-way switching,with a more compact structure and more precise flow control,making it ideal for scenarios where materials need to be alternately diverted to two downstream devices(such as silos,pipelines,or processing equipment).

Constructed to adapt to harsh industrial working conditions,the Two-way Flap Type Diverter Valve is available in a variety of materials to meet different application needs.For general industrial scenarios,carbon steel is adopted for its high mechanical strength and cost-effectiveness;for hygiene-critical industries(food,pharmaceutical,cosmetic),stainless steel(304/316)is used to meet strict hygiene standards;for abrasive materials(coal,mineral powder,cement),the flap and valve body can be equipped with wear-resistant liners(Hardox,polyurethane)to enhance wear resistance and extend service life.

Key features of this valve include reliable sealing,smooth operation,and strong adaptability.The flap is equipped with high-quality EPDM or PTFE seals,which tightly fit the valve body to prevent material leakage and cross-contamination between the two outlets,ensuring a clean and safe working environment.Actuation options are flexible,including manual(handwheel,lever)for small-scale or low-frequency operation,and pneumatic/electric for automated control.Pneumatic and electric models are equipped with position indicators and limit switches,enabling real-time monitoring of flap position and remote control,which can be seamlessly integrated with automated production lines.

Technical specifications can be customized according to actual application requirements,with size ranges from DN50 to DN600,operating temperatures from-20℃to 250℃,and pressure ratings suitable for low-pressure or gravity flow systems(up to PN10).Connection types include flange,welded,or bolted,allowing easy installation under hoppers,silos,chutes,or conveyor discharge ports,without occupying excessive space.

Widely used in mining,cement,food processing,chemical,pharmaceutical,power,and grain storage industries,the Two-way Flap Type Diverter Valve plays a vital role in optimizing material flow distribution.It is particularly suitable for scenarios such as alternately diverting grain to two silos,redirecting cement powder to two processing lines,or switching chemical granules between two conveying pipelines.With its simple structure,reliable performance,and low maintenance cost,it becomes an indispensable flow control component in two-way bulk material handling systems.
