Rising Disc Valves are crust-breaking bottom outlet valves designed for vessel and reactor draining applications where material buildup can interfere with flow. The VR Series design opens by lifting the disc upward into the vessel or reactor, helping break through crusted material so the process media can drain more effectively.
These valves are commonly used for low-viscosity product drainage and can be configured to meet specific process requirements.

Available options include metallurgy, seat arrangements, sealing systems, actuators, full jacketing, and dead-space-free vessel connections.
Rising Disc Valves are engineered to specification and are not typically inventoried as standard off-the-shelf products.
