Fluorine-Lined Ball Valve

Fluorine-Lined Ball Valve

Structural Features

• Valve body is generally made of carbon steel or stainless steel, with the inner wall entirely lined with PTFE.

• Common lining materials: F4 (PTFE), F46, PFA, PO, etc.

• The ball is also PTFE-coated/lined for full-flow-channel corrosion protection.

• The structure is mostly a floating ball, with flange connections as the primary method.

• The sealing surface has inherent corrosion-resistant and anti-stick properties.

PRODUCT DETAIL

Working Principle

• 90° rotation of the ball achieves switching.

• The medium only contacts the fluoroplastic liner, preventing corrosion of the metal valve body.

• Smooth flow path, no scaling, no media adhesion.

• Soft-seal structure, achieving zero leakage.

 

Core Advantages

1. Superior Corrosion Resistance
Resistant to almost all acids, alkalis, and organic solvents, including concentrated sulfuric acid, liquid alkali, ketones, esters, aromatics, and alcohols.

2. Non-stick and Self-lubricating
Media does not easily adhere, resulting in low flow resistance and high flow rate.

3. Wide Applicable Temperature Range
Standard temperature range: -20℃ to 180℃; PFA can withstand even higher temperatures.

4. Excellent Sealing Performance
Suitable for toxic, harmful, highly corrosive, and volatile media.

5. High Cost-Effectiveness
Using fluoroplastic-lined carbon steel instead of expensive alloy valves results in lower costs.

V-Type Ball Valve

V-Type Ball Valve

Structural Features

• V-shaped ball core: The hemispherical valve core has a V-shaped notch, which is the core component for regulation and shearing.

• Valve seat: It mates with the V-shaped notch to form a sealing surface. Soft seals (TFM, etc.) are suitable for clean media, while hard seals (welded or sprayed hard alloy) can be used in high-temperature, high-pressure, highly corrosive, or particulate-containing conditions.

Working Principle

• Regulation Function: As the valve core rotates, the overlap area between the V-shaped notch and the valve seat continuously changes, creating an equal percentage flow characteristic (opening degree and flow rate are logarithmically related), achieving high-precision control within the 30%-70% opening range.

• Shearing and Self-Cleaning: The V-shaped notch edge, in contact with the valve seat, cuts off fibers and small solid particles in the medium, preventing blockage; the relative movement between the valve core and valve seat during rotation scrapes away media residue on the sealing surface, achieving self-cleaning.

Forged Steel Ball Valve

Forged Steel Ball Valve

Key Features

• High-Strength Material: Forging process removes porosity and looseness, resulting in dense grains, high tensile strength, and superior wear resistance compared to cast steel.

• Reliable Sealing: Soft seal (reinforced PTFE/PPL) or hard seal (metal-to-metal), supporting double sealing, fireproof and anti-static.

• Stable Structure: Available in two-piece/three-piece flange connections, fixed ball or floating ball structure, and a split valve body for easy maintenance.

• Highly Efficient Opening and Closing: 90° rotation, low torque, fast opening and closing, suitable for frequent operation.

• Wide Temperature and Pressure Compatibility: Temperature range from -196℃ to 450℃, pressure rating from Class 150 to 1500.

Fixed Ball Valve

Fixed Ball Valve

Structural Features

• The valve core is a fixed shaft structure, positioned by bearings/sleeves at the top and bottom.

• The valve core itself does not move back and forth; sealing is achieved by the valve seat pressing against the valve core.

• It is a bidirectional sealing structure.

• Common connections: flange connection, welded connection.

Three-Way Ball Valve

Three-Way Ball Valve

Structural Features

• Valve body is a three-way structure with L- or T-shaped ports.

• The ball has an L-shaped or T-shaped channel.

• Mostly a floating ball structure; some large-diameter models are fixed ball.

• Common connections: threaded, flanged, welded, quick-connect.

• Actuation methods: manual, pneumatic, electric.
