Product Features
(1) All products undergo factory pressure testing: All products can provide factory pressure test reports.
(2) High-performance valve seat rubber: The rubber content of the valve seat is 50%, with a switch life of over 30,000 times.
(3) Soft back seat: Compared to hard back seats, soft back seats have a wider contact surface with the pipeline flange, better sealing performance, and do not require special flanges for butterfly valves.
(4) Axial sealing: The valve shaft is supported by four oil-free bearings, with a dual sealing structure design of O-ring and oil seal, resulting in lower torque and reliable sealing; for large diameter valves above DN350, the upper and lower shaft holes use packing box design, achieving sealing through compression of the packing.
(5) Surface coating: Uses epoxy resin powder coating, with strong adhesion, good weather resistance, suitable for indoor and outdoor use.
(6) Valve shaft blow-out prevention structure design: The pinless butterfly valve adopts a blow-out prevention structure design, allowing for electric head replacement under pressure.
(8) Pinless structure, soft back seat, installation does not require any special equipment, facilitating maintenance and replacement of parts.
