Valves for GGBS Experience

The company operating the Pinch Valves have confirmed that they are satisfied with the products, that the valves for GGBS are easy to operate and that they are working as anticipated. The life of the rubber sleeve is currently unknown as they are yet to be replaced after a few months. We estimate that the sleeves will have a long and healthy lifetime if our operating pressures are adhered to.
