High-quality soft sealing materials (such as EPDM and PTFE) combined with a precision valve seat structure design ensure tight fitting of the sealing surface and excellent wear resistance, achieving bidirectional zero-leakage sealing performance.Adopting an outside screw & yoke (OS&Y) structure, the valve stem lifts and lowers synchronously with the gate and is visible at all times. Operators can directly judge the valve's open/close status by the exposed length of the valve stem without additional testing equipment, effectively avoiding working condition disorder caused by misoperation.The gate and valve seat adopt a soft-seal fitting method, resulting in low friction during opening and closing. Coupled with a precision transmission structure, the operating torque is minimized, making both manual and electric actuation effortless and convenient.The selected soft sealing materials are eco-friendly with no harmful volatiles, complying with environmental requirements. The unobstructed flow channel design reduces medium flow resistance and lowers the energy consumption of the pipeline system, supporting green production.The valve body and bonnet adopt an integrated sealing structure with outstanding sealing performance, effectively preventing medium leakage. Some models can be equipped with special soft sealing parts for high and low temperatures, adapting to a temperature range of -40℃ to 120℃ to meet application needs under different environments.
