Three Way Diverting Control Valve is used in the occasion of adjusting three pipe tee. It has two types: HMT and HDT. When the nominal diameter and pressure difference is small, the junction valve can be used for diversion occasion. When nominal diameter is more than 80mm or pressure difference is larger, it only use for branch occasion.
It is equipped with multi–spring pneumatic diaphragm actuator or electric actuator. It has characteristics of small size, light weight, large output force, easy installation.

Step 1: Order and Design
Confirm customer requirements, including size, pressure rating, material, flow coefficient, connection type, and actuator configuration.
For the three way diverting control valve, engineers prepare drawings, select body structure, trim design, and sealing type to ensure accurate flow diversion performance.
Step 2: Forging & Casting
The main pressure-bearing parts such as valve body, bonnet, and flanges are produced by casting or forging according to the material specification.
For a three way diverting control valve, special attention is paid to the internal flow passages of the three-way body to ensure sound structure and stable flow distribution.
Step 3: Machining
After raw casting inspection, CNC machining is carried out for the valve body, seat pocket, stem hole, flange face, and internal trim parts.
The machining of the three way diverting control valve requires high precision on the three-port dimensions and sealing surfaces to guarantee reliable diverting control.
Step 4: Assembly
All qualified parts are cleaned and assembled, including valve plug, seat, stem, bonnet, actuator, positioner, and accessories.
During three way diverting control valve assembly, technicians carefully adjust stem travel and plug position to achieve smooth switching and accurate flow regulation.
Step 5: Testing & Quality Assurance
Each valve undergoes pressure test, leakage test, stroke calibration, and functional inspection.
For the three way diverting control valve, flow direction performance, shut-off capability, and actuator response are checked to ensure the valve meets application and quality standards.
Step 6: Painting and Finishing
After testing approval, the valve surface is cleaned, painted, labeled, and packed. Final finishing includes nameplate confirmation, protection of flange faces, and export-safe packaging before shipment.
