handwheel butterfly valve Description
Handwheel butterfly valve is a type of butterfly valve operation. The handwheel is manually rotated to drive the valve stem to drive the butterfly plate to rotate (usually 90°) to achieve control of fluid on/off or flow regulation. Its core structure includes valve body, butterfly plate, valve stem, sealing assembly and handwheel drive device, which is a low-cost, high-reliability fluid control device.
Core advantages Convenient operation and economy No external power (electricity/gas source) is required, manual operation can be completed to open and close, suitable for non-powered environments or emergency scenarios (such as remote water pipelines, power failure conditions); Simple structure, manufacturing cost is 40%-60% lower than that of electric/pneumatic butterfly valves, especially suitable for medium and low pressure projects with limited budgets. Low maintenance and high adaptability No complex control system, low failure rate, maintenance only requires regular lubrication (such as molybdenum disulfide-based grease) and sealing surface inspection; The handwheel can be equipped with a worm gear reduction mechanism to easily achieve low-torque operation (opening and closing torque ≤50N·m) of large-caliber (≥DN300) valves. Environmental compatibility
The valve body and handwheel can be made of cast steel, stainless steel or anti-corrosion coating, and can withstand acid, alkali, humidity and dust environments;
The flow resistance coefficient (Cv value) in the fully open state is 85% of that of the ball valve of the same diameter, suitable for high flow and low pressure loss scenarios.
