Hydraulic Solenoid Ductile Iron Gate Valve with 18 Months Warranty for Water Supply and Drainage

The transmission thread of the electric cast iron gate valve with concealed stem is located inside the valve body. During operation, the valve stem rotates while the gate plate moves vertically within the valve body, resulting in a compact design. In contrast, rising stem gate valves feature external transmission threads that allow visual monitoring of gate position but require more installation space.

The wedge gate valve's single gate design offers simplicity, reliability, and compact dimensions, making it suitable for diverse media and pressure conditions across various temperature ranges.

• Compact, robust construction with smooth flow path and minimal flow resistance

• Reliable sealing with asbestos graphite or flexible graphite materials
• Lightweight operation with easy handling
• Compatible with multiple flange standards and sealing surface configurations
• Widely used in petroleum, chemical, hydropower, and thermal power industries
