Product Overview

This 3 Way Electric Flanged Ball Valve is an industrial-grade automatic multi-way fluid control valve with electric intelligent drive as the core, L/T port 3 way flow channel as the main function, and GB/ANSI standard flanged connection. Driven by the electric actuator, the ball rotates 90° to accurately realize medium reversing, diverting, converging and cross switching in pipelines. It can be seamlessly connected to PLC/DCS industrial automatic control systems, with precise control, fast response, reliable sealing and strong pressure resistance. It is a special core equipment for automatic management and control of medium and large diameter industrial multi-way pipelines.

Available in full sizes DN15–DN300 (NPS 1/2″–12″), it strictly complies with global general industrial valve standards including GB/T 12237, ANSI B16.34, API 6D and ISO 17292. Widely used in HVAC, municipal water treatment, petrochemical, power plants, food and pharmaceutical, heat exchanger units and other medium and large industrial pipeline scenarios.

Key Features

1. Core Heavy-Duty Electric Actuator, Intelligent & Precise Control

   The product fully focuses on the core control demand of electric actuation, optimized for industrial working conditions of flanged 3 way ball valves:

   1. Full control mode coverage: supports on/off type and regulating type (4-20mA/0-10V analog) options, which can realize local manual operation, remote PLC/DCS system linkage, Modbus/Profibus bus communication, perfectly adapting to various industrial automation scenarios;
      

      ---

   2. Multiple safety protection: built-in over-torque, overheat, overload, anti-jam and anti-reverse protection, automatically triggers shutdown protection under abnormal working conditions to avoid damage to the actuator and valve body; standard equipped with real-time valve position feedback and fault alarm function, realizing full-process visual management and control;
      

      ---

   3. Full working condition adaptability: power supply covers AC220V/AC380V/DC24V industrial general voltage, standard IP65 protection grade, optional IP67/IP68 waterproof and dustproof grade, ExdⅡBT4/CT4 explosion-proof grade, perfectly suitable for harsh industrial working conditions such as humid, dusty, flammable and explosive scenarios;
      

      ---

   4. Emergency operation guarantee: built-in manual handwheel, which can manually open and close the valve under power failure, signal interruption and equipment failure conditions, ensuring the safety of emergency operation of industrial pipelines.

2. L/T Port 3 Way Flow Channel, Multi-Function for Full Scenarios

   The core adopts an integrated L/T port flow channel ball, with mirror polished inner wall, low flow resistance and no medium retention dead angle, which accurately matches the needs of different industrial working conditions: L Port Flow Channel realizes accurate two-way medium reversing and single-line on-off switching, replacing the combined function of 2 two-way valves; T Port Flow Channel realizes synchronous control of medium diverting, converging and three-way mixing, replacing the combined function of 3-4 two-way valves, greatly simplifying the industrial pipeline layout and reducing engineering construction and operation and maintenance costs.

   

3. Full Series Standard Flanged Connection, Reliable Sealing & Easy Installation

   The product fully focuses on the core requirement of flanged connection, the full series only adopts flanged connection design without other connection forms, and the flanged ends are 100% in line with global industrial general standards:

   1. Flange dimensions, sealing surface and bolt hole spacing strictly comply with GB/T 9113 and ANSI B16.5 industrial flange standards, with standard RF raised face sealing surface, optional RTJ ring joint face sealing for high pressure working conditions. It can be directly seamlessly connected with domestic and foreign flanged pipelines of the same standard without modification and adaptation;

   2. Flange butt seal matched with special metal spiral wound gasket / flexible graphite gasket, the sealing performance is far better than threaded connection. It remains no external leakage and no looseness even under high pressure alternating load, cold and heat cycle working conditions, with safe and stable long-term operation;
      

      ---

   3. The flanged connection is easy to disassemble and assemble, which can realize fast docking and disassembly of the valve and the pipeline. No hot work welding is needed to complete the installation, disassembly and daily maintenance of the valve, which greatly reduces the on-site construction and operation and maintenance costs of medium and large diameter industrial pipelines.

4. Structure Optimized for Working Conditions, Bidirectional Zero Leakage & Stable Operation

   Accurate structure matching according to diameter and pressure: Floating ball structure is standard for DN15-DN50, which realizes self-tightening sealing by medium pressure, the higher the pressure, the tighter the seal; trunnion mounted ball double seat structure is standard for full size range DN65-DN300, which greatly reduces the opening and closing torque under high pressure working conditions, and can still achieve stable opening and closing without jamming even under large diameter and high pressure working conditions. Standard equipped with PTFE/PPL wear-resistant soft seal valve seat, paired by high-precision grinding with the ball, the sealing grade reaches ANSI B16.104 Class VI bidirectional zero leakage. Optional metal hard seal type, high temperature and erosion resistance, suitable for harsh industrial scenarios such as steam and particle-laden media.

5. Full Series Material Options, Multiple Safety Structures, Stable & Durable

   All core wetted parts provide full material options of WCB carbon steel, 304/316/316L stainless steel, adapting to various industrial working conditions such as water, steam, oil, gas, corrosive media. The full series is equipped with anti-static structure, bottom-mounted T-type blow-out proof stem, API 607 fire-safe structure, eliminating potential safety hazards such as electrostatic explosion, stem rushing out and medium leakage. It is stable and durable for long-term operation, with extremely low operation and maintenance cost in the whole life cycle.
