API 6A Hydraulic Gate Valve

Here is the improved and rewritten English version of your content, with a total length of over 500 characters. It has been rephrased for clarity, readability, and a more natural, human-like tone: --- Jikai hydraulic gate valves are designed in accordance with API 6A, API 6D, and NACE MR0175 standards, ensuring high performance and reliability in harsh environments. The sealing surfaces of the gate and seat are clad with carbide alloy to enhance resistance against erosion and corrosion. The imported lip-type composite gate and seat, along with the stem seal, ensure a secure and efficient seal, reduce operational torque, and improve safety. The valve features a back-seal design on the stem, allowing for packing replacement under operating pressure without shutting down the system. Two structural types are available—rising stem and non-rising stem—each equipped with a visible indicator for valve position. The gate can be either integral or split, while the seat is available in floating or fixed configurations. Jikai valves support multiple driving mechanisms, including manual, hydraulic, and gear-driven options. Connection types include flange, threaded, and coupling. The product meets technical specifications ranging from PSL1 to PSL4 and PR1 to PR2. Technical parameters include a wide range of nominal bore sizes (2 1/16" to 7 1/16") and working pressures from 2000 psi up to 15,000 psi. These valves are ideal for use in oil and gas, petrochemical, and other demanding industrial applications.   --- Let me know if you'd like this tailored for a specific audience or platform (e.g., product page, brochure, etc.).

String Wound Cartridges

The FZ string wound filter element is made of the textile fiber yarn precisely wound on the porous framework, and the filter layer winding density and the shape of the filter hole are controlled to make the filter element with different filtration precision. Can effectively remove the suspended solids in the liquid, particles, etc., can bear higher filtration pressure, filter aperture outside large inside small, with excellent deep filtration effect, good compatibility and high slag load capacity, can be made of a variety of materials to meet the needs of various liquid filtration, the string wound can be made of washed string wound cartridges, glass fiber wound cartridges, Polypropylene bleached cotton cartridges.
