FlowCon ABM DYNAMIC BALANCED TEMPERATURE CONTROL VALVE INSTALLATION AND OPERATION INSTRUCTION FlowCon ABM 15-40mm, 1/2”-1 1/2” Install the FlowCon ABM 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 ABM with its Optimizer® ball valve, it is recommended to ensure the ball valve is downstream of the balancing device. INSTALL THE VALVE HOUSING WITH THE FLOW DIRECTIONAL ARROW POINTING IN THE CORRECT DIRECTION. The FlowCon ABM valve is available with double union end connections, i.e. figure 1. Figure 1 end connections ordered. The threads on both the connection and piping should be cleaned carefully. As these models are union end connected, the union nuts and the end connections should be removed for installation. O-rings are supplied with the valve body and used to seal the connections. It is recommended to grease the o-rings with silicone grease before installation. IMPORTANT: Never use mineral oil or petrol based grease or oil on the o-rings. Please make sure these are in place in the o-ring grooves in the inlet and outlet of the valve body, when installing the housing and REMEMBER TO TIGHTEN THE UNION NUTS TO ENSURE SEALING. For all thread connections please 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. Soldered end: REMOVE THE END CONNECTIONS FROM THE HOUSING BEFORE SOLDERING. THIS ENSURES THAT THE O-RINGS AND INTERNAL PARTS ARE NOT DAMAGED BY HEAT. Pressure/temperature fittings (p/t plugs) are available upon request for the ABM 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 the p/t plugs, the valve body can be ordered with plugs for the body tappings. Each plug is sealed by a gasket.
