Parker Conflow’s Code 18/19 is a heavy duty stop valve that is used to shut off flow of water safely and securely in pipelines in underground mining, to isolate areas for maintenance and extension.

This screwdown valve enables large flows in large diameter pipes to be isolated by the gradual shut off of the valve. This eliminates hydraulic shock waves or water hammer being created which would damage the steel pipes and fittings. Used as an inline stop valve for a fire hydrant, Code 18/19 prevents damage to downstream equipment. It can also be used to isolate valves for maintenance.
The fully open position gives a true full flow capability thus creating minimal resistance in the pipeline. The 4" unit incorporates a balanced pressure feature, which enables the valve to be opened and closed at high pressure with the minimum of effort.

Code 18/19 is available in 2", 2 1/2", 3" and 4" sizes and operates at a maximum working pressure of 105 bar (Code 18), 125 bar (Code 19).
