A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball to control flow through it. It is open when the ball’s hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle. The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve’s status. Ball valves are durable, performing well after many cycles, and reliable, closing securely even after long periods of disuse. These qualities make them an excellent choice for shutoff and control applications
All material handling systems by Lion Bulk Handling operate with a wide type range of valves, connectors and other equipment, including butterfly valves, ball valves, check valves and gate valves. These valves are checked and approved by Lion Bulk Handling to secure the best performance for your system. We are also pleased to assist with any spare part requests.
A flap valve is a valve which opens by flipping a round or rectangular gate/wedge out of the path of the dry cargo. The distinct feature of a flap valve is the sealing surfaces between the flap and seats are planar, so flap valves are often used when a straight-line flow of dry cargo and minimum restriction is desired.
This assembly is used to decrease air pressure from the rig’s work air supply to the pressure required for pneumatic conveying. This is usually around four bar. The pressure-reducing station consists of two reducers, a safety valve, ball valves and pressure gauges. Two reducers are installed in parallel so that one can keep working while the other is replaced or repaired. The ball valves are used to select the correct pressure reducer. The pressure gauges are installed before and after the pressure reducer. The reducers are set by our engineers during commissioning and locked afterwards.
