Product Overview
This Electric Fully Welded Ball Valve is a professional on-off valve specially designed for smart pipe networks and remote automatic control scenarios. Its core adopts an integrally welded valve body made of Q235B/Q355B high-quality carbon structural steel plate with CNC rolling and fully automatic one-piece welding, without split connections, bolt fastenings and aging-prone gaskets, completely eliminating the risk of valve body external leakage from the root.
Equipped with an intelligent electric actuator as standard, the valve can realize remote opening and closing, precise regulation and status feedback. The full-series soft seal structure is suitable for low pressure working conditions of PN10-PN25 (Class150), covering full sizes DN50-DN1200. It strictly complies with GB, ANSI/ASME and API 6D standards, and is the core control equipment for automatic pipe networks such as urban smart gas, district heating, municipal water supply & drainage and long-distance transmission pipelines.
Key Features
1. Carbon Steel Plate Fully Welded Body, Zero Leakage & Settlement Resistance
2. Standard Intelligent Electric Actuator, Remote & Precise Control
The valve is matched with a high-performance intelligent electric actuator as the core, optimized for industrial pipe network automation scenarios, with outstanding core advantages:
Multi-Mode Control: Supports on/off type / regulating type options, adaptable to local manual control, remote DCS/PLC system linkage control, 4G wireless intelligent control, perfectly meeting the construction needs of smart municipal pipe networks;
Multiple Safety Protection: Built-in over-torque protection, overheat protection, overload protection and anti-jam protection, which automatically triggers protection under abnormal working conditions to avoid damage to the actuator and valve body;
Real-Time Status Feedback: Equipped with valve position feedback and switch in-place signal output as standard, which can upload valve opening and closing status and fault alarm signals to the central control system in real time, realizing full-process visual management and control;
