FlowCon A / AB / ABV DYNAMIC BALANCING VALVE WITH ADJUSTABLE INSERT INSTALLATION AND OPERATION INSTRUCTION 15-25mm, 1/2”-1” FlowCon A 15-50mm, 1/2”-2” FlowCon AB 15-40mm, 1/2”-1 1/2” FlowCon ABV Install the FlowCon A / AB / ABV as called for in the design drawings. Although the performance of the valve is not affected either way, industry standards call for balancing devices to be installed on the downstream side of the terminal unit. Especially for the ABV with its isolation ball valve, it is recommended to ensure the isolation valve is downstream of the balancing device. INSTALL THE VALVE HOUSING WITH THE FLOW DIRECTIONAL ARROW POINTING IN THE CORRECT DIRECTION. The FlowCon A valve (Model Nos. A15.X, A20.X and A25.I.K) is available with fixed female-by-female threaded connections, i.e. figure 1. The FlowCon AB valve (Model Nos. AB15.X, AB20.X, AB25K.X, AB25.X, AB32.X, AB40.I and AB50.I) is similarly available with fixed femaleby-female threaded connections, i.e. figure 2. Figure 2 The thread standard for the AB model is equal to what is available for the A model (except for DN25 small, DN40 and DN50 which currently are only ISO). For all threaded connections pls. clear threads on both valve and piping of debris. Sealant such as pipe dope or teflon tape is recommended. WHEN USING HEMP AS PIPE SEALANT, ENSURE NO STRANDS ARE LEFT IN THE VALVE OR PIPING. Pressure/temperature fittings (p/t plugs) are available upon request for the AB valve. Before finger mounting the p/t plugs in the body tappings, please. seal the threads of the p/t plugs (DO NOT OVER TIGHTEN). Alternatively to p/t plugs, the valve body can be ordered with plugs for the body tappings. Each plug is sealed by a gasket. Figure 1 The thread standard for the A model is either ISO 228, which is a straight metric thread (compatible with BS-2779) or NPT threading standard, depending on the product number ordered (except for DN25 which currently is only ISO). For all threaded connections pls. clear threads on both valve and piping of debris. Sealant such as pipe dope or teflon tape is recommended. WHEN USING HEMP AS PIPE SEALANT, ENSURE NO STRANDS ARE LEFT IN THE VALVE OR PIPING.
