Core structure: Adopting a direct-flow channel design (optional angular structure), the valve disc moves up and down along the centerline of the valve seat, achieving reliable shut-off through forced sealing; the exposed stem design is combined with a trapezoidal transmission thread, allowing for intuitive judgment of the valve's opening and closing status. Standard handwheel drive is provided, with a short opening and closing stroke and convenient operation.
Connection form: Standard flange connection, compliant with ASME B16.5, GB/T 9113, etc., supporting various flange face forms such as RF, FM, RJ, etc. Installation is convenient, suitable for various industrial pipeline systems.
Material configuration: The valve body can be made of carbon steel (WCB), stainless steel (CF8/CF8M, CF3/CF3M), copper alloy (such as C95800 aluminum bronze), etc.; the sealing surface can be welded with Stellite hard alloy, featuring excellent wear resistance, corrosion resistance, and erosion resistance, suitable for water, steam, oil products, corrosive media, and seawater under various working conditions.
Pressure and diameter range: Covering Class 150~2500 (PN16~PN420) pressure grades, the diameter can range from DN15 to DN300 (1/2"~12"), meeting the diameter and pressure requirements of different pipeline systems.
Drive mode: Standard handwheel drive is provided, and options include pneumatic, electric, gear drive, etc., suitable for remote control or automatic conditions.
Application scenarios: Widely used in various industrial pipelines, especially suitable for scenarios requiring frequent opening and closing, high pressure difference, toxic / flammable / explosive media, or precise throttling regulation.
