Product Overview

This 3 Way T Port Ball Valve is a multi-way fluid control valve with T-type orthogonal flow channel as the core functional body, model code Q45F. Through 90°/180° rotation of the ball, it accurately realizes five core functions of pipeline medium: splitting, converging, mixing, three-way full flow, and flow direction switching. Different from the single reversing function of L-type ball valves, one T-type ball valve can replace the combined function of 3-4 two-way valves, greatly simplifying the pipeline layout and reducing engineering costs.

Available in full sizes DN15–DN300 (NPS 1/2″–12″), it strictly complies with global general industrial valve standards including GB/T 12237, ASME B16.34, API 6D and API 608, with optional flanged/threaded connection methods. Widely used in HVAC, water treatment, petrochemical, food and pharmaceutical, energy pipe network and other multi-way medium control scenarios.

Key Features

1. Core T Port Flow Channel Design, Multi-Function for Full Working Conditions

   The product fully focuses on the core design of T port. The ball flow channel adopts an orthogonal T-type structure, the inner wall of the flow channel is mirror polished with rounded smooth transition, low flow resistance and no medium retention dead angle. Full-scenario fluid control can be realized through ball rotation:

   1. Splitting Mode: One inlet and two outlets, evenly distribute the single medium to two branches, suitable for multi-way water supply and raw material distribution scenarios;
      

      ---

   2. Converging Mode: Two inlets and one outlet, merge two different media into the same pipeline for mixed output, suitable for cold and hot water mixing and material mixing scenarios;
      

      ---

   3. Three-Way Full Flow Mode: Three pipelines are connected at the same time to realize medium circulation, pressure balance and multi-channel synchronous transmission;
      

      ---

   4. Reversing Switching Mode: Any two channels can be connected and the third channel can be cut off, taking into account the basic flow direction switching function.

      Standard equipped with four-seat sealing structure with balanced force, which maintains stable sealing even under high pressure working conditions and eliminates cross flow and internal leakage problems.

2. Structure Optimized for Working Conditions, Stable Operation & Reliable Sealing

   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 DN65-DN300, which greatly reduces the opening and closing torque under high pressure working conditions, and still opens and closes smoothly without jamming under large diameter conditions.

   Two sealing options are provided: soft seal type is standard equipped with PTFE/PPL wear-resistant valve seat, paired by high-precision grinding, the sealing grade reaches ANSI B16.104 Class VI bidirectional zero leakage; metal hard seal type is overlaid with Stellite hard alloy, high temperature and erosion resistance, suitable for harsh scenarios such as steam and particle-laden media.

3. Standard Industrial Connection, Easy Installation & Wide Adaptability

   GB/ANSI standard flanged connection is the core standard configuration. Flange dimensions, sealing surface and bolt hole spacing strictly comply with GB/T 9113 and ASME 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 and seamlessly connected with industrial pipelines of the same standard, with stable sealing performance and convenient disassembly and maintenance. Small diameter DN15-DN50 can choose NPT/BSP/Rp standard internal thread connection, suitable for equipment built-in and narrow space installation scenarios.

4. Full Series Material Options, Wide Corrosion Resistance Coverage

   All core wetted parts provide a full range of industrial material options to adapt to various working condition requirements: WCB carbon steel for conventional water, oil, steam working conditions; CF8(304), CF8M(316) stainless steel for corrosive media and sanitary working conditions; A105 forged steel for high pressure working conditions, with dense material without defects, excellent pressure and impact resistance.

5. Flexible Operation Modes & Multiple Safety Structures, Stable & Durable

   Full coverage of operation modes: standard manual handle/worm gear drive, optional pneumatic/electric actuator, which can easily realize remote automatic control of pipelines and adapt to industrial automatic control systems.

   The full series is equipped with industrial-grade safety structures as standard: 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.

Applications

HVAC cold and hot water mixing and temperature control systems, water treatment multi-way dosing/splitting/backwashing pipelines, petrochemical medium mixing and synthesis process, food and beverage material mixing and distribution systems, gas/fuel oil multi-way distribution pipe networks, industrial circulating water systems, boiler auxiliary multi-way medium control, automated production line fluid distribution systems.

Product Summary

This 3 Way T Port Ball Valve firmly focuses on the core advantage of T port flow channel, and has five core functions of splitting, converging, mixing, full flow and reversing. One valve replaces multiple valves, greatly simplifying the pipeline layout. At the same time, it has the characteristics of industrial-grade pressure-resistant sealing, convenient installation, wide material adaptability and flexible operation modes, covering full diameter sizes and flanged/threaded dual connection methods. It is the preferred special valve for medium distribution, mixing and switching control in industrial multi-way fluid pipelines.
