Product Description

Product Description

1. D343H Series Worm Gear Hard-Sealed Butterfly Valve | Robust Flow Control Solution
The D343H series worm gear hard-sealed butterfly valve is engineered for demanding industrial applications. Featuring a metal seated seal and worm gear drive, it ensures reliable shut-off and precise flow control of water, steam, oil, and mildly corrosive media. Ideal for petroleum, chemical, and heating systems.

2. Worm Gear Drive | High Torque & Stable Operation
Equipped with a precision worm and gear mechanism, the valve offers smooth manual operation with self-locking capability, suitable for large-diameter applications. The fully enclosed gearbox provides protection against dust and splashes, and can be adapted for handwheel, lever, or electric actuator operation for local or remote control.

3. Multi-Layer Metal Hard Seal | Leak-Free Under High Pressure & Temperature
The seat incorporates a stainless steel and graphite laminated structure, with the sealing surface precision-ground and hardened. It maintains excellent sealing performance under high-temperature (≤425°C) and high-pressure (PN16/25/40) conditions, ensuring long service life and minimal maintenance.

4. Triple Eccentric Design | Reduced Wear & Operating Torque
Based on a triple eccentric geometry, the disc fully disengages from the seat during operation, significantly reducing friction and wear. The streamlined disc design minimizes flow resistance, offering both precise regulation and improved system efficiency.
