A Cast Iron (C.I.) sluice valve is a type of valve that is made of cast iron and is used to control the flow of liquids in an open channel, such as a canal, ditch, or watercourse. The valve typically consists of a gate or shutter that sits inside the valve body, which can be opened or closed to control the flow of water. The gate or shutter can be a solid or a split type. The valve is operated by a handle or a wheel that turns a threaded stem, which in turn moves the gate or shutter.
They can handle high pressure and temperature, and are suitable for use with a wide range of liquids. They are also easy to maintain and repair. The sluice valves are mainly used to control the flow of water in open channels and are often used in conjunction with other types of valves, such as gate valves, to control the flow of water through an entire system. They are designed to withstand harsh environmental conditions and are typically used for large flow rate.
It is important to match the valve with the correct pressure class and the correct type of fluid. Some standards for Cast iron sluice valves are BS 5163, BS 1868, API 600, API 6D, MSS SP-81, and ISO 10434.
