Advantage
Why Choose Hearken Flow Floating Ball Valve?
Corrosion Resistance
Hearken Flow floating ball valves are available with wear-resistant and corrosion-resistant body materials, such as stainless steel and alloy steel, for demanding applications. Furthermore, Hearken Flow floating ball valves offer flexible configurations tailored to media characteristics, offering seat options including PTFE, EPDM, Viton, and metal seals. They provide stable operation even with harsh media, including acids, bases, and chemical solutions.


Fast and Smooth Opening and Closing
The Hearken Flow floating ball valve, with its low-torque design, utilizes a low-friction seat material and a mirror-polished internal ball, significantly reducing sticking during opening and closing. This reduces energy consumption and project costs while providing smoother and faster opening and closing.
Suitable for Harsh Media


Hearken Flow’s floating ball valves offer robust media adaptability. Featuring a corrosion-resistant, high-temperature valve body with thermal expansion compensation, they guarantee stable operation even with high-temperature steam, high-viscosity, particulate slurries, or corrosive chemicals, effectively safeguarding your process continuity.
Production
Floating Ball Valve Production Process
Hearken Flow enforces strict quality control from raw casting to final dispatch. We ensure full traceability and consistency, delivering floating ball valves that perform reliably in your critical systems.
Raw Material Verification (PMI)
Before production, every batch of raw material undergoes Positive Material Identification (PMI) spectrographic testing. By strictly verifying compliance with ASTM and NACE MR0175 standards, we eliminate the risk of material inconsistencies, ensuring your valves withstand corrosive environments and high-pressure loads without structural failure.
Precision Spherical Grinding
The heart of a floating ball valve is the ball itself. We employ advanced CNC grinding to achieve a mirror-like surface finish and perfect roundness. This precision reduces friction against the seats, resulting in significantly lower operating torque for easier actuation and a tighter, more reliable seal.
Clean Room Assembly
To protect the soft seating materials, all components undergo ultrasonic cleaning to remove microscopic machining residues. Assembly is conducted in a contaminant-free environment, preventing debris-induced seat damage and ensuring smooth, leak-free operation from the very first cycle.
100% API 598 Pressure Testing
We refuse to rely on spot checks. Every single Hearken Flow valve is subjected to rigorous API 598 / ISO 5208 hydraulic and air pressure testing. This guarantees that only units with zero leakage and verified torque values leave our factory, providing you with “install-and-forget” confidence.

Easy Installation, Fast Maintenance

Inline Maintenance Capability
Hearken Flow top-entry floating ball valves are engineered for true in-line serviceability. Internal components—including the ball, seats, and stem—can be inspected or replaced quickly by simply removing the bonnet, without cutting the valve from the pipeline. This critical feature drastically reduces maintenance downtime and eliminates the risks associated with pipe realignment.

Compact High-Strength Architecture
Engineered with optimized wall thickness and high-tensile materials, Hearken Flow floating ball valves offer a superior strength-to-weight ratio without compromising pressure ratings. This compact design minimizes structural load on your piping system and reduces the need for expensive pipe supports, making it ideal for weight-sensitive applications like offshore platforms and skid-mounted units.

Floating Ball Valves by Application
FAQ
A: In a floating design, the ball moves slightly under pressure to seal. In a trunnion design, the ball is fixed on bearings and the seats move to seal against the ball.
A: In a floating ball valve, the ball is not held by a trunnion. When the valve is closed, upstream pressure pushes the ball against the downstream seat, creating a tight, leak-proof seal.
A: Floating ball valves are inherently bi-directional. They can effectively seal flow coming from either the upstream or downstream direction.
A: These valves are typically designed for low to medium-pressure systems. They are most commonly rated for ANSI Class 150 and 300, or PN16 to PN40.
A: The most common soft seat materials are PTFE and RPTFE (Reinforced PTFE). For high-temperature or high-pressure needs, PEEK or Devlon seats are used.
