DINKONDA GLOBAL Power Plants Special Worm Gear 90 ° Rotation Reduction Manual

Product Specification

DINKONDA GLOBAL Power Plants Special Worm Gear 90 ° Rotation Reduction Manual Mechanism WCB Carbon Steel Valve Body, PTFE Soft Seal/metal Hard Seal, Top Mounted Fixed Ball Valve

Product Overview
The upper mounted fixed ball valve adopts a top mounted integral valve body structure, with the ball body designed as a fixed ball. The upper and lower valve shafts support the ball body and are matched with a worm gear reduction manual mechanism. It is driven by a handwheel to achieve 90 ° rotation and complete the connection and disconnection of the pipeline medium. The valve does not need to be removed from the pipeline as a whole, and the internal components can be inspected directly by opening the cover from the top of the valve body, greatly reducing on-site maintenance downtime. The valve body is made of WCB carbon steel and is suitable for American standard pressure ratings. It is commonly used in large-scale process systems for continuous production in industries such as petroleum, natural gas, chemical, and long-distance pipelines.

Structural Composition
Valve body, valve cover, fixed ball, upper and lower supporting valve shaft, valve seat sealing component, valve stem, packing component, worm gear reducer, blue handwheel, flange connection end, valve chamber discharge interface.
1. Valve body: WCB carbon steel casting, integral upper structure, high strength, resistant to high pressure impact;

2. Sphere: Fixed ball structure, medium pressure supported by upper and lower bearings, small opening and closing torque, suitable for large diameters;

3. Valve seat: PTFE soft seal or metal hard seal can be selected to adapt to different temperature and medium working conditions;

4. Drive device: worm gear reduction mechanism, large diameter handwheel, easy to operate;

5. Top mounted structure: online maintenance, no need to dismantle pipeline flanges, reducing maintenance costs.

Core Features
1. Installation online maintenance: Maintenance only requires removing the top valve cover, keeping the valve on the pipeline, reducing the workload of pipeline emptying and disassembly;

2. Fixed ball structure, strong pressure bearing capacity, stable opening and closing torque, easy operation under large-diameter working conditions;

3. Direct flow channel, low flow resistance coefficient, and low pressure loss during medium transportation;

4. Bidirectional sealing, installation without medium flow restriction;

5. Flange connection, good rigidity, suitable for heavy working conditions such as long-distance pipelines and storage tanks;

6. Configurable valve chamber pressure relief and discharge interfaces to ensure valve chamber safety.
