Long Handle Curved Channel Stem Ball Valve Ball

Long Handle Curved Channel Stem Ball Valve Ball

The Long Handle Curved Channel Stem Ball Valve Ball is a high-precision engineered valve core component designed for extreme service conditions where remote operation, thermal isolation, and safety-critical performance are required.

This design integrates an extended stem structure with an internal curved channel system, enabling multifunctional use such as thermal management, media guidance, pressure relief routing, and protected instrumentation wiring.

Unlike conventional valve balls, this component is specifically developed for cryogenic, high-temperature, toxic media, and unmanned operation environments. The long handle structure physically isolates the actuator from the process media, while the internal curved channel provides an engineered pathway for thermal break, injection, monitoring, or cable protection.

It is widely used in LNG systems, liquid hydrogen infrastructure, high-pressure refining units, remote energy stations, and hazardous chemical storage applications.

About
Zhejiang Boshi Valve Technology Co., Ltd.

Zhejiang Boshi Valve Technology Co., Ltd was built initially in 2005. The company is located in the was built initially in 2005. The company is located in the No. 951, Jinhai Avenue, Yongxing Subdistrict, Longwan District, Wenzhou City, Zhejiang Province Building 25, 1st to 4th Floors. Boshi valve is a high tech valve ball supplier which integrates design, production, sales, and service. Our company provide high-quality products and services for customers at home and abroad.

 

Our products are backed by in-house facilities for roughcast forging and pressing, steel plate rolling and welding, seamless pipe forming, and CNC machining. Through a systematic, integrated, and process-driven management approach, we strictly control product quality and delivery schedules. As a result, we are highly praised and trusted by both new and long-term customers..

 

The materials produced and manufactured by our company include 2Cr13, A105, LF2, F316, F304, F51, and F53 include floating (Q41) balls, fixed (Q47) balls, three-way (T-shaped) balls, four-way balls, curved (L-shaped) balls, and V-shaped adjustment balls, special hard sealing balls, and marble or steel balls in various specifications, often using sub-arc welded hollow sleeves.

 

Surface treatments for spherical components include electroplating (ENP), ion TCC, and alloy spray coating (STL), ensuring high hardness, corrosion resistance, and wear resistance. The rough blanks undergo processes such as forging, casting, and coil welding, followed by heat treatments like solution treatment, annealing, tempering, normalizing, and quenching. We uphold the business philosophy of “quality first, integrity-based,” and continue to innovate with new technologies, new processes, and new materials to actively develop new product varieties.
