Why choose us?
Advanced materials & surface engineering
We specialize in difficult-to-machine materials including duplex stainless steel, titanium, Inconel, zirconium, and engineering ceramics. Combined with HVOF, plasma spray, DLC/TiN coating, and laser cladding technologies, our valve balls deliver excellent wear resistance, corrosion resistance, and long-term sealing performance.
Experienced technical support & global supply
Supported by a technical team with over 30 years of industry experience, we offer customized valve ball solutions based on different application requirements. As an authorized supplier for global companies including Emerson and Flowserve, our products have been exported to more than 20 countries and regions
Precision manufacturing for severe service
Our machining accuracy reaches roundness ≤0.001 mm, supporting stable sealing performance under high pressure, high temperature, and corrosive working conditions. Products are validated through rigorous cycle testing to ensure durability and operational reliability.
Strict quality control & full traceability
From raw material inspection to final testing, every production process follows strict quality standards. We provide 100% inspection and complete production traceability, helping customers reduce quality risks and improve supply chain confidence.
Types of Customized Components
The Customized Components Produced By Our Company Primarily Fall into the Following Categories:
NACE valve stems
NACE valve stems are industrial valve shafts manufactured and treated to meet strict corrosion-prevention standards established by NACE International (formerly the National Association of Corrosion Engineers). They are designed to withstand highly corrosive "sour service" environments, such as oil and gas extraction, where hydrogen sulfide (H₂S) is present.
Extended valve stems
Extended valve stems (or valve stem extenders) are mechanical attachments that screw onto existing tire valves to make them longer, angled, or more accessible. They are highly useful for vehicles with deep-set rims, dual rear wheels ("duallies"), or large RVs where the original valve is too hard to reach with an air hose or tire pressure gauge.

Benefits Of Customized Components
NACE valve stems
Enhanced safety through reduced risk of catastrophic failure
Extended service life in corrosive environments
Reduced maintenance costs and unplanned downtime
Compliance with industry regulations and standards
Improved reliability in critical applications
Reduced environmental and safety risks
Lower total cost of ownership over equipment lifecycle
Extended valve stems
Remote on/off control: By extending the stem, the actuator can be installed at ground level or on an operating platform, allowing remote control of a valve located underground or in a distant location.
Improved safety for operators: In environments with high/low temperatures, toxic media, or confined spaces, operators can stay away from the hazardous area, reducing the risk of burns, exposure, or injury.
Reliable flow shut-off or opening: Just like a standard gate valve, it controls flow by raising or lowering the gate, providing a tight seal and effective isolation when needed.
Suitable for deep-buried or inaccessible areas: Ideal for installations such as underground chambers, the bottoms of storage tanks, or any area where direct access is difficult. It improves operational efficiency and ease of maintenance.
Compatible with various actuators: The valve can be operated manually or combined with electric or pneumatic actuators, supporting both manual control and automation requirements.
