Product Description

Double Half Shaft Butterfly Valve
A double half shaft butterfly valve is a flow-control device featuring two semi-axles (half shafts) integrated into a disc positioned within a pipe. This design minimizes friction and wear by distributing rotational forces evenly across the disc. The valve operates via a quarter-turn mechanism, enabling quick opening/closing. Constructed from durable materials like stainless steel or cast iron, it often includes a resilient seat (e.g., EPDM) for tight sealing. Key advantages include low torque requirements, compact structure, easy maintenance, and bidirectional flow capability. Ideal for handling liquids, gases, or slurries, it is widely used in water treatment, HVAC, chemical, and power industries. Available in manual, pneumatic, or electric actuation, it suits moderate pressure/temperature applications efficiently.
