burkert 0404電磁閥 Installation: Before installing valve ensure that piping etc. is free of foreign matter (metal fillings, seal material, welding scale etc.). burkert 0404電磁閥 PTFE tape is recommended for sealing ports. burkert 0404電磁閥Arrow on valve body gives flow direction. burkert 0404電磁閥 Installation as required but preferable with coil uppermost. Installation in this position tends to prevent foreign matter remaining in pilot valve (increased life). burkert 0404電磁閥 A strainer upstream of valve, protects against effects of foreign matter. burkert 0404電磁閥 Do not put any loads on coil unit. burkert 0404電磁閥Pipework should be supported such that valve body is not under strain. Do not allow a pipe-end or sealing material to block the pilot bore within the valve outlet. Inlet and outlet of valve must be fullbore and pipework unrestricted. burkert 0404電磁閥
