We address the challenges of complex system integration by supporting a wide array of connection methods—from flanges and threads to butt welding, socket welding, and clamps. Experience superior sealing performance and a design that facilitates easy installation and removal, ensuring your system remains flexible, leak-free, and efficient.
Excellent Sealing Performance
The Hearken Flow ball valve supports a variety of high-airtightness structural designs, including floating balls, fixed balls and special customized ball valves. Floating ball valves can be bidirectionally sealed under medium pressure, while fixed ball valves have higher sealing performance under higher pressure conditions.
At the same time, Hearken Flow ball valves provide you with hard seals and soft seals with excellent corrosion resistance and high temperature resistance, and adapt the most suitable solutions for different working conditions.

Why Choose Hearken Flow Ball Valves?
Ball Valves by Applications
Long Life and Wear Resistance
Hearken Flow ball valves are made of corrosion-resistant materials that have passed strict testing, including stainless steel, cast iron, Hastelloy, titanium alloy, plastic (PTFE, UPVC, etc.) and industrial ceramics. The surface of the ball is hardened and precision polished to effectively improve the wear resistance, ensure stable sealing in long-term operation, extend service life, and reduce the number of shutdowns for maintenance.


Low Torque Design
The Hearken Flow ball valve uses low friction, high temperature resistant seals and high strength wear-resistant bearings to effectively reduce wear and aging caused by long-term operation and avoid the increase of operating torque with the use time. The three-piece modular structure facilitates quick maintenance and replacement of parts, which can timely eliminate the problem of medium blocking and ensure smooth opening and closing of the valve.
High Temperature And High Pressure Resistance


Hearken Flow ball valves are available in a precision combination of high-strength metal materials, stainless steel alloys, and high-temperature resistant seals, graphite or metal bellows. Our high pressure ball valve body and ball are made of high-temperature resistant alloys, with full bore design to reduce fluid resistance, and high precision ground ball and seat to achieve leak-free sealing. The pressure self-tightening structure makes the seal more reliable the higher the medium pressure is, and the metal-to-metal or composite sealing technology can withstand high temperatures above 500℃. In addition, Hearken Flow’s strict heat treatment process and international standard testing can ensure your long-term stability in petrochemical, electric power and other extreme working conditions.
Production
Ball Valve Production Process
Raw Material Inspection
Hearken Flow conducts strict material composition analysis, mechanical property testing, dimensional accuracy and appearance defect inspection on all raw materials before ball valve production to ensure that they fully meet the product design and working conditions.
Valve Body Processing
The valve body processing of Hearken Flow ball valves includes mechanical processes such as rough turning, fine turning, thread/flange surface processing, and surface treatments such as sandblasting, electroplating, spraying or polishing according to different working conditions. After processing, the dimensional accuracy, sealing surface flatness and surface quality are fully tested.
Ball Processing
The ball of Hearken Flow ball valve is chrome-plated or sprayed after rough turning, fine turning and grinding, and the surface finish and sealing performance are improved through high-precision polishing process. Then the key indicators such as dimensional accuracy, roundness, surface roughness, dynamic balance and hardness are tested.
Components Processing
Valve stems, sealing rings, packing and other components will be tested for dimensional accuracy, coaxiality, straightness and hardness to ensure that each component has good matching accuracy and durability with the ball and valve body.
Assembly Test
After the standardized assembly process is completed, all ball valves will be subjected to shell strength test, two-way sealing test, low-pressure air tightness test, opening and closing torque test and other performance verifications in turn to ensure that the product is reliably sealed, opening and closing is smooth, and meets the delivery standards.
