A. Material Composition

Valve Body: Constructed from high – quality stainless steel, commonly grades 304 or 316. Grade 304 stainless steel, with its 18% chromium and 8% nickel content, provides excellent general – purpose corrosion resistance, making it suitable for applications where the media is not highly corrosive, such as in water and air systems. Grade 316 stainless steel, containing molybdenum, offers enhanced resistance to pitting and crevice corrosion, making it ideal for more aggressive media, like those in chemical processing or marine environments.
Ball: The ball of the three – way valve is precisely machined from stainless steel. In the V – style ball valve, the ball has a V – shaped opening. This V – notch is carefully crafted to ensure accurate flow control. For both types, the ball surface may undergo additional treatments, such as hard – facing with materials like stellite, to enhance wear resistance when handling abrasive media.
Seat: Typically made of materials like PTFE (Polytetrafluoroethylene) or RPTFE (Reinforced PTFE). PTFE seats offer low friction, excellent chemical inertness, and reliable sealing properties. RPTFE seats, reinforced with fibers like glass or carbon, provide increased mechanical strength and durability, making them suitable for higher – pressure and more demanding applications.
Stem: Also made of stainless steel, the stem is designed to connect the ball to the electric actuator. It is precision – machined and often treated with anti – corrosion measures, such as plating or heat treatment, to ensure smooth operation and long – term reliability.

B. Pressure and Temperature Ratings

Pressure Rating: The three – way flange ball valve and the thread V – style ball valve can handle a range of pressures. Commonly, they are designed to operate within pressure classes such as PN16 (1.6MPa), PN25 (2.5MPa), and PN40 (4.0MPa). This allows them to be used in various industrial pipelines, from low – pressure water distribution systems to high – pressure chemical processing lines.
Temperature Range: The operating temperature range varies depending on the seat material. With PTFE seats, the valves can typically operate from – 20°C to 150°C. For applications requiring higher temperatures, specialized seat materials can extend this range, enabling the valves to function in environments such as steam lines or high – temperature chemical reactions.

C. Connection and Actuation

Connection Type:
- Three – Way Flange Ball Valve: Features flange connections that comply with international standards like ASME B16.5. The flange type can be raised face (RF) for general applications or ring – joint face (RJF) for high – pressure and high – temperature scenarios. Flange connections ensure a reliable and leak – tight joint, making it easy to integrate the valve into existing pipeline systems.
- Thread V – Style Ball Valve: Utilizes threaded connections, which are convenient for applications where space is limited or quick installation and disassembly are required. The threads conform to standard specifications, ensuring compatibility with a wide range of pipes and fittings.
Electric Actuation: Both valves are equipped with electric actuators. These actuators are designed to provide precise control over the rotation of the ball. They can be operated remotely, allowing for automation of the flow – control process. The electric actuator typically comes with features such as position feedback, which provides real – time information about the valve’s position (fully open, fully closed, or at an intermediate position) to the control system. It can be powered by various voltage sources, including 220V AC, 110V AC, or 24V DC, depending on the specific application requirements.

III. Feature Description

A. Three-Way Flange Ball Valve

Diverting/Mixing Capability: The three-port design (typically L-type or T-type) enables seamless redirection of media—either splitting one inlet into two outlets (diverting) or merging two inlets into one outlet (mixing). In chemical plants, this eliminates the need for multiple valves to switch between process lines, simplifying system design.
Bubble-Tight Sealing: Precision-machined stainless steel ball and PTFE seats form a tight seal, preventing cross-contamination between ports. This is critical in food processing, where mixing potable water and cleaning agents must be controlled without leakage.
Electric Three-Way Switching: The actuator allows remote selection of flow paths (e.g., A→B, A→C, or B→C), enabling rapid process changes. In water treatment, this lets operators switch between raw water and treated water lines with a control signal, reducing manual intervention.

B. Threaded V-Style Ball Valve

V-Notch Flow Regulation: The ball’s V-shaped notch (30° or 60°) creates a linear flow characteristic, meaning flow rate changes proportionally with valve rotation. This makes it ideal for throttling applications, such as dosing chemicals in pharmaceutical reactors or controlling slurry flow in mining.
Abrasion Resistance: The V-notch design minimizes turbulence, reducing wear on the ball and seat when handling abrasive media (e.g., pulp, slurries). Combined with 316 stainless steel, this extends service life in harsh environments.
Modulating Control: The electric actuator supports 0°~90° positioning, allowing precise adjustment of flow rates (from 0% to 100%). In HVAC systems, this maintains stable temperatures by fine-tuning water flow to heat exchangers.

IV. Manufacturing Processes

Material Preparation: 304/316 stainless steel billets undergo spectral analysis to verify chemical composition (e.g., 18Cr-8Ni for 304, 16Cr-10Ni-2Mo for 316). For high-corrosion applications, 316L (low carbon) is used to prevent intergranular corrosion.
Precision Machining:
- Three-way bodies are CNC-machined to create symmetric ports and smooth internal flow paths, minimizing pressure drop.
- V-style balls are milled to exact notch angles (tolerance ±0.5°) and polished to Ra ≤0.8μm for consistent flow characteristics.
- Threads (for V-style) and flanges (for three-way) are machined to ASME standards, ensuring compatibility with pipes.
Actuator Integration: Electric actuators are mounted and calibrated to sync with ball movement. For three-way valves, actuators are programmed to lock into discrete positions (0°/90°) for port switching; V-style actuators use proportional control for continuous modulation.
Testing: Each valve undergoes:
- Hydrostatic test (1.5×PN) to check body integrity.
- Seat leakage test (1.1×PN with air/water) to ensure no cross-port leakage.
- Actuator function test to verify position accuracy (±1°).

V. Product Advantages

Multifunctionality: Three-way valves reduce system complexity by handling diversion/mixing with one unit; V-style valves combine shut-off and throttling, eliminating the need for separate control valves.
Automation Efficiency: Electric actuation with feedback integrates into PLC/DCS systems, enabling real-time monitoring and remote control. In industrial plants, this cuts labor costs and reduces human error.
