Product Overview
The HSVA D71X lever-operated wafer butterfly valve provides compact 90-degree operation for isolation and flow regulation in water supply, drainage, power, chemical and building-services pipelines. The catalogue lists a QT450 ductile-iron body and disc, stainless-steel stem and shaft, and a nitrile-rubber resilient seat. Its short face-to-face length, low operating torque and simple maintenance suit projects where space and reliable manual operation matter.
For overseas distributors, EPC contractors and project buyers, HSVA can review the required DN schedule, pressure rating, medium, temperature, flange standard, face-to-face dimensions, material selection and quantity. Send the project specification, drawing and certificate requirements for valve selection and quotation.
