Our CNC machines deliver precision machining for valve bodies, bonnets, flanges and components, meeting diverse dimensional and assembly specs. 

    Designed for weld overlay on internal walls and selected surfaces of valve bodies, pipes, flanges, ball valve spheres and reducers, accommodating components with different geometries.

    Suitable for machining components used in valves and pipe fittings. It accommodates workpieces up to 1,500 mm in length, with a maximum swing over the bed of 800 mm. In addition to turning, it supports drilling, boring and reaming operations.

    Used for tempering large carbon steel valve components. The maximum furnace temperature is 1,200°C; the actual tempering temperature is set according to the material and process requirements.

    Suitable for small valve castings, pipe fittings and metal components that can withstand tumbling. It removes residual sand, rust and oxide scale, preparing surfaces for subsequent machining and coating.

     Adjustable to suit different loads and packaging requirements. Film tension can be controlled by adjusting the turntable speed and motor speed.

    Used for Vickers hardness testing of thin specimens, small components, hardened layers and coatings. Suitable for material inspection and heat treatment quality evaluation of valve components.

Test range: HV1–HV30.

    Based on the principle of atomic emission spectrometry, this dual-channel system for iron-base and nickel-base materials can rapidly and accurately identify the types and contents of elements in samples. 

    Used to analyze alloying elements and verify material grades in valve bodies, bonnets, stems and other metal components. Supports material verification during incoming inspection, production and final inspection.

    Used to measure the wall thickness of valve bodies, bonnets and pipes, verify dimensions after machining, and assist in assessing localized thinning.

    Used to detect internal discontinuities in valve castings, forgings and welded joints, including cracks, inclusions and lack of fusion, supporting the assessment of internal component quality.

    Used to verify valve shell integrity and sealing performance. Pressure is applied and maintained for a specified duration while checking for leakage to assess the pressure integrity and tightness of the valve body, connections and sealing surfaces.
