RGV Roller Gate Valve

Ideal for heavy duty, large scale isolation of bulk dry materials

The Mucon RGV Roller Gate Slide Valve has been designed to meet the needs of the bulk materials handling industry for a robust, heavy duty isolation valve.

It is as modular and configurable as it is robust and reliable.

Its patented blade support system provides uninterrupted flow of material through the valve body, but can still accommodate an inlet deflector if required by the application.

Pre-loaded and self wear compensating seals help prevent the loss of process material and are replaceable without the need to remove the valve from the process line.

Whilst we offer a range of standard sizes from 150mm (6″) to 600mm (24″) square, our manufacturing methods allow us to easily produce custom sizes in square or rectangular configurations.

The valve can also be supplied with a square to round adapter for the inlet and/or outlet.
