Products Description
Overview
Worm gear wafer butterfly valve is a type of quarter-turn valve commonly used to regulate or isolate fluid flow in pipelines. Here's a detailed overview.
🔧 Definition
A worm gear wafer butterfly valve combines a wafer-style body (a compact valve design installed between two pipe flanges) with a worm gear operator (a gear mechanism that allows precise manual control of the disc position).
⚙️ Main Components
Body (Wafer Type)
Sandwiched between two pipe flanges.
Lightweight and space-saving.
Usually made of cast iron, ductile iron, stainless steel, or PVC.
Disc
The rotating element that opens or closes the flow.
Typically stainless steel or coated for corrosion resistance.
Seat
Provides sealing between the disc and the body.
Made from materials like EPDM, NBR, PTFE, or Viton.
Stem/Shaft
Connects the disc to the actuator or gear operator.
Worm Gear Operator
A handwheel turns a worm gear, which slowly rotates the disc.
Offers mechanical advantage, making it easier to operate large valves or handle high pressure.
