Floating Ball Sealing Structure Performance Comparison

Conventional Two-Piece Flanged Ball Valve

· Valve stem leakage may occur after long-term exposure to high-temperature media.

· Without a standardized mounting platform, additional brackets are required for actuator installation.

· Maintenance and replacement operations are relatively complicated.

Bolaisi Two-Piece High Platform Ball Valve

· Gland-type valve stem packing structure provides extremely low leakage performance.

· Sealing performance remains stable after high and low temperature cycle testing.

· ISO5211 high platform enables direct installation of electric or pneumatic actuators.

· Convenient on-site maintenance and easier equipment integration.

Key Structural Design Advantages

Two-Piece Split Valve Body

The two-section valve body features high casting accuracy and consistent machining dimensions. The split structure allows easier inspection and maintenance without removing the entire pipeline system.

Gland-Type Valve Stem Packing Seal

Multi-layer packing compression effectively prevents external leakage along the valve stem. The packing can be replaced separately during maintenance, reducing downtime and service costs.

ISO5211 Standard High Mounting Platform

The integrated high platform design provides accurate positioning and allows direct mounting of pneumatic or electric actuators without additional adapter brackets.

Floating Ball Double-Directional Sealing

The floating ball design supports bidirectional pressure sealing. The medium pressure automatically pushes the ball against the valve seat, ensuring stable sealing performance.

Temperature and Media Sealing Performance Tests

The valve has been tested under two typical operating conditions: normal-temperature fluids and high-temperature steam environments.

Soft Seal (PTFE Seat) Testing

Testing Conditions:

· Temperature: ≤150℃

· Continuous circulation testing with water, gas, and oil

Test Results:

· No obvious seat wear

· Zero leakage during air pressure testing

· Suitable for clean water, gas, and normal-temperature oil applications

Metal Hard Seal Testing

Testing Conditions:

· Temperature: ≤280℃

· Continuous operation with high-temperature steam and slightly particle-containing media

Test Results:

· Excellent resistance to high-temperature erosion

· Strong wear resistance and particle impact resistance

· No internal or external leakage under high-temperature conditions

The dual sealing design allows this Two Piece High Platform Flanged Ball Valve to cover a wide range of industrial fluid applications. Users can select suitable sealing materials according to actual working conditions, reducing inventory costs while improving equipment adaptability.
