    Product Details

    Product Description
    The choke valve stem is a core moving component in oil drilling, oil and gas extraction, and wellhead throttling equipment, controlling flow, regulating pressure, and cutting off the medium. It is primarily used in conjunction with oilfield choke valves, regulating valves, and gate valves. The product uses high-strength alloy structural steel/stainless steel specifically designed for oilfields as its base material, formed through multiple precision machining processes including forging, CNC precision turning, and grinding.
    The surface is reinforced with a wear-resistant alloy using high-velocity oxygen fuel (HVOF) spraying, providing exceptional wear resistance, erosion resistance, acid and alkali corrosion resistance, and high-pressure resistance. It can operate stably for extended periods in harsh oilfield conditions, including sand-containing oil and gas media, alternating high and low temperatures, and high-pressure impacts, effectively reducing equipment wear, extending replacement cycles, and lowering on-site maintenance costs.
    The product adheres to industry-standard precision, ensuring high dimensional accuracy and smooth assembly. Customization based on drawings and samples is supported, making it a preferred component for oil machinery parts and wellhead equipment maintenance and replacement.

    Frequently Asked Questions (FAQ)
    Q What is an HVOF coated choke valve stem and what is it used for?
    An HVOF (High-Velocity Oxygen Fuel) coated choke valve stem is a precision-machined moving component used in oilfield choke valves, regulating valves, and gate valves. It controls flow, regulates pressure, and cuts off media in oil drilling, oil and gas extraction, and wellhead throttling systems. The HVOF coating provides exceptional wear and corrosion resistance for use in harsh oilfield environments.
    Q What materials are available for the choke valve stem?
    The choke valve stem is available in a range of oilfield-grade materials including 40CrNiMoA, 42CrMo, 304/316/316L Stainless Steel, and 17-4PH precipitation-hardened stainless steel. Custom material selection based on specific operating conditions, customer drawings, or samples is also supported.
    Q What working pressure ratings are supported?
    The choke valve stem is available in multiple pressure grades: 2000psi (2K), 3000psi (3K), 5000psi (5K), 10000psi (10K), 15000psi (15K), and 20000psi (20K), covering standard, high-pressure, and ultra-high-pressure applications. This makes it suitable for a wide range of oilfield and wellhead equipment.
    Q How much does the HVOF coating extend the service life of the valve stem?
    The HVOF supersonic sprayed alloy coating significantly improves the valve stem's resistance to wear, erosion, acid/alkali corrosion, and cavitation. Compared to ordinary uncoated valve stems, the service life is extended by 3 to 5 times, which greatly reduces downtime, replacement frequency, and overall on-site maintenance costs.
    Q Can the choke valve stem be customized according to our drawings or equipment specifications?
    Yes. Full OEM/ODM customization is supported. Customers can provide drawings, samples, or equipment model information, and the valve stem can be tailored in terms of dimensions (length 80mm–600mm), coating type, coating thickness (0.03–0.5mm), material, and connection structure. It is compatible with various domestic and international brands of choke and regulating valves.
    Q What coating options are available for the valve stem surface treatment?
    Multiple HVOF coating materials are available to suit different operating conditions, including: cobalt-bonded tungsten carbide (WC/Co), cobalt-chromium-bonded tungsten carbide (WC/CoCr), cobalt-chromium tungsten alloy (Stellite 20#/NiCr), nickel-chromium-bonded chromium carbide (Cr₃C₂/NiCr), nickel-based alloy (Ni60/Ni55), and nickel-based tungsten carbide (WC/Ni).
