FlowCon S-JUST 1B95097 - 03/2021 Installation and Operation Instruction The FlowCon S-JUST insert is used with FlowCon AB valve housings DN15-25 (1/2”-1”): Insert Setting and Installation Prior to installing the FlowCon S-JUST insert (supplied from factory in setting 1.8) in the valve housing, the system should be properly flushed. Blank valve covers are available to be installed during flushing. It is recommended to grease the O-rings located around the S-JUST with silicone grease before installing the insert in the valve housing. The desired Kv is set by adjusting the insert with a special adjustment key. Scale setting is located on the ‘neck’ of the insert where the white digits printed on black, numbered 1 to 5, indicate full turns and the top white digits printed on the red counter wheel, numbered 0 to 9, indicate 1/10 of full turn. Kv setting may be done either before or after the insert is installed in the valve housing and based on measured differential pressure on the p/t plugs and Kv setting, flow is calculated: Q (m 3 /hr) = Kv * √ΔP(kPaD) * 100 Setting 1.0 1.1 1.2 1.3 1.4 1.5 1.6 1.7 1.8 1.9 2.0 2.1 2.2 2.3 2.4 2.5 2.6 2.7 2.8 2.9 3.0 3.1 3.2 3.3 3.4 3.5 3.6 3.7 3.8 3.9 4.0 4.1 4.2 4.3 4.4 4.5 4.6 4.7 4.8 4.9 5.0 FlowCon S-JUST Kv (m 3 /hr) 0.00 0.14 0.29 0.43 0.57 0.72 0.86 1.0 1.1 1.3 1.4 1.6 1.7 1.9 2.0 2.2 2.3 2.4 2.6 2.7 2.9 3.0 3.2 3.3 3.4 3.6 3.7 3.9 4.0 4.2 4.3 4.5 4.6 4.7 4.9 5.0 5.2 5.3 5.5 5.6 5.7 Cv (GPM) 0.00 0.16 0.34 0.50 0.66 0.84 1.0 1.2 1.3 1.5 1.6 1.9 2.0 2.2 2.3 2.6 2.7 2.8 3.0 3.1 3.4 3.5 3.7 3.8 3.9 4.2 4.3 4.5 4.6 4.9 5.0 5.2 5.3 5.5 5.7 5.8 6.0 6.1 6.4 6.5 6.6 This paper is a supplement to the FlowCon General Instruction Latest release of any FlowCon material is available on www.flowcon.com Page 1 of 2
