Technical Features & Design Advantages:

1. Efficient Gear Operation System  

• Precision Mechanical Design：The valve incorporates a worm gear mechanism that creates optimal mechanical advantage through precision gear engagement. This system ensures smooth operation while providing inherent self-locking capability to maintain secure valve positioning.

• Durable Performance Components：Manufactured with hardened gear components and advanced surface treatments, the mechanism delivers extended service life and consistent performance. The robust construction withstands frequent operation in demanding industrial environments.

• User-Friendly Operation：Featuring an ergonomic input design, the system enables effortless control with significantly reduced operating effort. The maintenance-optimized design ensures long-term reliability while minimizing service requirements.

2. Space-Saving Non-Rising Stem Design  

• Compact Installation: Stem rotates internally without vertical movement, reducing required overhead clearance by 50%.

• Protected Mechanism: Fully enclosed stem prevents corrosion, impact damage, and unauthorized operation

• Ideal for Confined Spaces: Perfect for valve pits, underground chambers, and crowded mechanical rooms

3. Superior Sealing Performance  

• Resilient Seated Design: EPDM or NBR encapsulated wedge ensures bubble-tight shutoff (EN 12266-1 Class A)

• Zero Leakage: Rubber-to-body sealing eliminates metal-to-metal contact, preventing leakage even after thousands of cycles

• Corrosion-Resistant Materials: Stainless steel stem and epoxy-coated body ensure long service life in harsh environments

4. Durable Construction Materials

• Body Material: High-grade ductile iron (EN-GJS-500-7) with 250μm fusion-bonded epoxy coating

• Stem: AISI 420 stainless steel with precision-machined trapezoidal threads

• Gear Components: Heat-treated carbon steel gears with corrosion-resistant coating

5. Maintenance-Friendly Features

• Lubrication-Free Operation: Self-lubricating bronze bushings and sealed bearings eliminate routine maintenance  

• Visual Position Indicator: Clear open/close status display on gear operator  

• Easy Access: Removable gearbox cover simplifies inspection and service when required
