Ceramic Ball Valve

Key Features:

1. Superior Corrosion Resistance: Zirconia/alumina ceramics are resistant to almost all acid, alkali, and salt media, and do not rust or corrode.

2. Ultra-High Wear and Erosion Resistance: The high hardness of the ceramic means it experiences almost no wear under particulate media and slurry erosion, resulting in a lifespan far exceeding that of stainless steel.

3. Stable Sealing and Non-Stuck-Up: The smooth ceramic surface does not scale or adhere, ensuring stable switching torque and preventing jamming.

4. Zero Leakage: Precision ceramic mating seals enable bidirectional sealing.

5. No Media Contamination: The ceramic's high inertness prevents metal ion precipitation, making it suitable for high-purity and clean environments.

Disadvantages: Relatively brittle, not resistant to severe impacts or sudden temperature changes; careful selection and installation are required.

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.

3 PIECE BALL VALVE

3 PIECE BALL VALVE

Structural Features

• The valve body is composed of three forged steel pieces bolted together.

• The valve core, seat, and seals are all housed in the middle valve body section.

• Common connection methods: threaded (NPT/BSP), welded, quick-connect.

• Generally small diameter: mainly DN6～DN100.

• Mostly floating ball structure, reliable sealing, and compact size.

Thin Ball Valve

Thin Ball Valve

Structural Features

• Ultra-compact: 40%~60% shorter in length and 30%~50% lower in height than standard ball valves

• Lightweight: 30%~50% lighter, easier installation

• Connection: Mainly wafer type (clipped between two flanges), flange type is also available

• Opening and Closing: 90° rotation of the ball for quick shut-off/connection

• Low Flow Resistance: Full-bore design ensures smooth media flow and low pressure loss

• Excellent Sealing: Soft seal (PTFE/PPL) or metal seal, zero leakage

• Optional Features: Anti-static, fire-resistant structure, safety locking

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.
