3 Way Electric Ball Valve Description
Three-way electric ball valve drives the ball to rotate through the electric actuator to switch, divert or merge the flow direction of the medium in the pipeline, which is suitable for automation control scenarios.
Core components:
Valve body and ball:
Stainless steel (304/316L) or fluorine-lined material (such as F46) is used, which has strong corrosion resistance and is suitable for acid and alkali media;
The surface of the ball is ground to Ra≤0.4μm, forming a zero leakage seal with the PTFE valve seat.
Drive mechanism:
The electric actuator supports 4-20mA signal input, the control accuracy is ±1°, and the response time is ≤3 seconds;
The explosion-proof motor complies with the ExdⅡBT4 standard and is suitable for flammable and explosive environments.
Flow channel type and working principle
Flow channel design:
L type: Connect two orthogonal pipelines to achieve right-angle flow switching (such as inlet → outlet A/B);
T type: Support three-way diversion, confluence or full-pass, and flexibly control complex processes.
Action process:
Open: Rotate the valve stem counterclockwise, the ball rotates 90° after leaving the valve seat, and the flow channel is fully open;
Close: Rotate the valve stem clockwise, the ball and the valve seat are wedge-shaped to achieve double sealing.
Technical characteristics and performance parameters
Pressure resistance: Conventional PN16-PN40, high-pressure type can reach PN64 (DN400);
Temperature range:
Soft seal type: -10~150℃ (PTFE);
Hard seal type: -29~425℃ (metal seal);
Sealing level: Zero leakage (leakage level VI), in line with API 608 standards.

3 Way Electric Ball Valve
Applications
Chemical process: acid-base medium switching (such as alternating transportation of 98% concentrated sulfuric acid and liquid alkali);
Energy system: high-temperature steam diversion control (thermal power plant pipeline);
Food and pharmaceutical: aseptic fluid confluence and filling (requires clamp quick-install connection).
Selection and installation points
Selection suggestions:
For highly corrosive working conditions, choose fluorine-lined valve body (such as F46) + PTFE seal;
Four-seat hard seal structure is preferred for high temperature and high pressure environment, supporting automatic pressure relief;
When remote control is required, select DCS integrated actuator.
Installation specifications:
Horizontal installation, reserve 90° rotation space for valve stem;
Use metal spiral wound gasket for flange connection, and evenly distribute bolt preload;
After debugging, 1.5 times pressure test is required (maintain pressure for 10 minutes)
