Product Description

Product Overview & Main Features

The Electric Gate Valve with Worm Gear Head is specifically engineered for robust industrial pipeline isolation. Designed with a multi-turn flanged structure, this valve provides reliable flow control for large-scale fluid management systems, ensuring long-term operational stability and reducing maintenance frequency.

• Worm Gear Reduction Head: Equipped with a heavy-duty worm gear reduction head, this valve delivers significant torque output. This design ensures stable and smooth operation for large-size valve opening and closing, effectively preventing mechanical shock and extending the equipment's service life.

• Dual Operation Mode: Features a dual-control mechanism combining electric automatic control for regular operations and a manual handwheel for emergency override. This guarantees continuous pipeline safety and operational control even during unexpected power failures.

• Wedge Gate Structure: Engineered with a precision wedge gate structure, it provides zero-leakage bi-directional shut-off. Under full-open status, it maintains extremely low flow resistance, maximizing fluid transfer efficiency and reducing energy consumption for pumping systems.

• Multi-Turn Electric Actuator: The integrated multi-turn electric actuator supports remote PLC/DCS signal control. It continuously feeds back valve position signals to the central control system, enabling precise automation and monitoring for complex industrial setups.

• IP65 Protection Grade: Designed to withstand harsh conditions, the IP65-rated enclosure ensures reliable performance in outdoor and demanding industrial working environments by protecting sensitive electrical components from dust and water ingress.

• Flange Connection: The standardized flange connection facilitates straightforward installation and routine maintenance. With a wide size range available, it easily adapts to various project demands and pipeline specifications.

6 Core Design Details

1. Flat-Bottom Valve Seat

Traditional gate valves often suffer from poor sealing due to foreign objects—such as stones, welding rod ends, welding slag, or cement—getting trapped in the bottom groove after pipeline installation. This resilient seated gate valve utilizes a flat-bottom design consistent with the pipeline interior. This prevents debris accumulation, ensures smoother fluid flow, and significantly extends the service life of the valve by reducing wear on the sealing surfaces.

2. Full Rubber Coating on Gate Plate

The gate plate is fully encapsulated with rubber both internally and externally. Utilizing advanced domestic rubber vulcanization technology, the gate plate maintains precise dimensions after processing. This results in a firm, durable bond between the metal core and the rubber coating, providing superior elasticity and preventing the rubber from peeling off under high-pressure fluid conditions.

3. Corrosion Resistance

Constructed from durable ductile iron, the valve body is thoroughly coated with epoxy resin powder. This protective layer effectively prevents body corrosion and rusting, ensuring long-term structural integrity. It meets national hygienic standards for drinking water applications and is equally suitable for demanding sewage treatment environments.

4. Multi-Channel O-Ring Design 

The stem sealing incorporates a multi-channel O-ring design. This configuration significantly reduces friction resistance during opening and closing cycles, minimizing the risk of water leakage. For specific project requirements, it can be upgraded to an online maintenance (self-sealing) type, allowing for convenient sealing ring and packing replacement without removing the valve from the pipeline.

5. Precision Cast Valve Body

Manufactured via precision casting, the valve body features highly accurate geometric dimensions. This advanced manufacturing process ensures reliable sealing performance directly from the cast, eliminating the need for additional internal machining and preserving the material's natural strength.

6. Lightweight Construction

Despite its robust performance, the integrally precision-cast valve body offers a lightweight profile. This high-strength yet lighter construction simplifies handling during transportation, eases the installation process, and reduces the structural load on the pipeline system.
