I. Core Structural Features
- Drive Type Electric actuator drive (the electric device at the top is visible in the picture, compatible with the BZ series actuator), supporting remote/local control. Some models integrate a manual operating mechanism, which can be manually switched in emergency situations, in compliance with JB/T 8528 "Technical conditions for general-purpose valve electric devices" ;
- Connection Method Flange connection, dimensions conform to GB/T 9113 "Integral steel pipe flanges" ;
- Sealing Structure Soft seal (PTFE valve seat) or hard seal (metal-to-metal sealing surface) optional, high sealing reliability, conforming to GB/T 12237 sealing performance requirements;
- Valve Body Structure Two-piece/three-piece flange-connected valve body (the picture shows the flanged ball valve body), the flow path is designed as full-bore or reduced-bore, with low fluid resistance and low opening and closing torque;
- Protection Level The electric device has an IP65 (some models reach IP67) protection level, suitable for outdoor, humid and other complex environments, conforming to GB/T 4942.2 "Degree of protection provided by enclosures of low-voltage switchgear and controlgear" 。
