Parker Conflow's Code 11 is a check valve that is used in water dust suppression systems that keeps the pipelines "charged" with water so that the spray heads energise instantaneously when the supply valve is turned on.

它被安裝在管道系統中，使流體的流動是必需朝著一個方向， 該設計是這樣的，當閥門水平安裝時，流體流動的方向上只需要克服閥芯元件的重量，即可打開閥門，因此通過閥門的阻力很小。如果系統要求垂直安裝閥門，則可以增加內置輕彈簧，實現閥芯預緊。 It is fitted into pipelines on systems where the flow of fluid is required in one direction only. The design is such that only the weight of the valve component needs to be overcome in the direction of fluid flow and hence the resistance across the unit is small. If system requirements necessitate the valve to be fitted vertically, then a light spring can be added.
The valve is suitable for both hydraulic and pneumatic systems and is designed especially for silent operation on equipment with pulsating or reverberating action (e.g. air compressors).
該閥可提供的尺寸為 1/2, 1, 2, 3和 4的大小，工作壓力上限為125bar。Available in 1/2", 1", 2", 3" & 4" sizes and to a maximum working pressure of 125 bar.
尺寸為1/2到 2英寸的大小是由黃銅材質生產，尺寸為2到 4的大小為鋼材質結構。The 1/2" to 2" sizes are of Brass construction and 2" to 4" sizes of Steel construction.
