Features
1、Connection Standard, High Pressure Capacity: Adopting flanged connection形式, securely fastened to pipeline flanges with bolts, providing reliable sealing and convenient installation/disassembly. Capable of withstanding high pipeline stress and working pressure, suitable for nominal pressure PN1.6~PN10.0 and larger diameter industrial pipeline systems.
2、Low Flow Resistance, High Flow Capacity: The internal medium通道 in the valve body is unobstructed. After the gate opens, the medium flows straight through the valve with minimal flow resistance coefficient and low pressure loss, particularly suitable for large-diameter, long-distance transmission pipelines with pressure loss requirements.
3、High Automation Level, Flexible Control Methods: Equipped with an electric actuator, enabling on-site manual operation, remote centralized control, and automated program interlock control. The electric device typically features overload protection, stroke and torque control functions, ensuring stable and reliable opening and closing.
4、Reliable Sealing, High Temperature Adaptability: The sealing surfaces of the gate and seat are treated with stainless steel overlay welding or hardfacing alloy, offering excellent wear resistance, corrosion resistance, and scratch resistance. The stem and gate utilize trapezoidal thread transmission, high-quality packing sealing system, meeting operating conditions for media such as steam and oil at working temperatures ≤425°C.
5、Rigid Structure, Stable Opening and Closing: Featuring a rigid gate design that moves vertically along the body guide tracks, ensuring minimal vibration and stable operation during opening and closing. The stem undergoes quenching, tempering, and surface treatment for high strength and good transmission efficiency, ensuring smooth switching of large-diameter valves.
6、Wide Application Range, Convenient Maintenance: The main valve body material is WCB carbon steel or cast stainless steel, widely applicable in industrial fields such as petroleum, chemical, power, and metallurgy. The face-to-face dimensions comply with national standards, components have strong interchangeability, and inspection and replacement are relatively convenient.
