■ Overview
XRW600 series pneumatic low-load butterfly valve is a rotary type regulating valve with small volume, light weight and large rated flow coefficient. It is especially suitable for large diameter, large flow, rich muddy slurry or boiler flue gas control. This series of products are available in standard and rear seats. The product's nominal pressure rating is PN2.5, 6, 10, and the diameter is DN50~DN2000, and the flow characteristics are approximately equal percentage.
When pneumatically switching manually, use the side-mounted handwheel mechanism method: pull out the positioning pin, pull the handle up, the worm wheel and the worm mesh, press the positioning pin, and rotate the handwheel to change the flow cross section. When manually switching to pneumatic, the handle is reversed.
