FlowCon SH 15-40mm / 1/2”-1 1/2” EXTERNALLY ADJUSTABLE DYNAMIC BALANCING VALVE INSTALLATION AND OPERATION INSTRUCTION FlowCon SH 15-40mm, 1/2”-1 1/2” Install the FlowCon SH valve either in the supply or return pipe work for the unit. It is recommended that a strainer be installed prior to the valve body to prevent damage or blockage due to debris. INSTALL THE VALVE HOUSING WITH THE FLOW DIRECTIONAL ARROW POINTING INTHE CORRECT DIRECTION. The valve body is available with double union end connections, i.e. figure 1. Two types of end connections are available for use with the union nut: Threaded (male or female): The thread standard is ISO 228, which is a straight metric thread (compatible with BS-2779) or NPT threading standard, depending on the 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 a 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 threaded connections please clear hreads 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 (sweat): REMOVE THE END CONNECTIONS FROM THE HOUSING BEFORE SOLDERING. THIS ENSURES THAT THE O-RINGS AND INTERNAL PARTS ARE NOT DAMAGED BY HEAT. Valve bodies are as standard supplied with body tappings plugged. Alternatively, the valve body can be ordered with pressure/temperature fittings (p/t plugs) for the body tappings. Before finger mounting the p/t plugs in the body tappings, please seal the threads of the p/t plugs. (DO NOT OVER TIGHTEN).
