Please help us fulfil this obligation by observing the environmental instructions in this manual: Chapter "Storage and transport" Chapter "Disposal"
Siphons Siphons Application/Function. Use Siphons according to DIN 68 are a cooling zone for protection of the pressure transmitters against too hot process media. Through condensation in the elbow pipe, a protective water accumulation is formed. Even in applications with hot steam, a medium temperature < 00 C on the transmitter is ensured. There are two different series of siphons: the u-form for horizontal pressure extraction and the circular form for vertical pressure extraction. bar 00 80 6 0 00 00 00 00 C Fig. : Temperature derating - max. permissible pressure depending on the process temperature Mounting/operation Configuration With steam applications, the siphon must be filled with water before setup. Hence, you can avoid that until condensation, hot steam penetrates directly into the pressure transmitter. The siphon must not be isolated. Move under www.vega.com to "Products" and "Siphon". 5

Blocking valves Blocking valves Application/Function Mounting/operation Configuration. Use Blocking valves according to DIN 670 enable simple mounting, setup and dismounting of a pressure transmitter with process fitting G½ or ½ NPT. The ventilation screw with single valves enables the removal of residual air as well as a relieve of the residual pressure between valve and pressure transmitter. The ventilation/test valve with double blocking valves enables two functions with closed process valve: Ventilation of the pressure transmitter Checking the pressure transmitter via a connected pressure calibrator. The valve is opened by turning it anticlockwise or closed by turning it clockwise. The sealing to the medium is made via a flat seal or metallically, the seal of the valve spindle is a gland packing. The ventilation opening must be assigned and the ventialtion carried out in such a way that neither persons nor the environment will be in danger by penetrating medium. For ventilation of a blocking valve proceed as follows:. Open valve (). Open ventilation screw () carefully until air escapes. Close the ventilation screw () as soon as medium penetrates The ventilation is hence finished. Rust, sand or similar pollution in the medium can build up around the valve seat, especially when the system is flushed out before the first setup. This can cause leakage around the valve seat. The spindle must therefore be fully opened to permit flushing out. When the prepressed packing is stored for a longer time, its sealing ability can deteriorate. If necessary, the seal must be retightened at the time of setup. The procedure is described in chapter "Maintenance and fault rectification". Move under www.vega.com to "Products" and "Valve". 9

5 Valve blocks 5 Valve blocks Application/Function Mounting/operation Configuration 5. Use Valve blocks enable simple installation and setup of a differential pressure transmitter. Process valves are used to block the transmitter to the process. When the process valves are closed, the equalization valve enables a pressure compensation for the measuring chambers. This allows the zero point of the pressure transmitter to be adjusted. The 5-fold valve block has two additional outlet valves for blowing out the process lines or checking the differential pressure transmitter. The valves are opened (turning anticlockwise) or closed (turning clockwise) with hand wheels. The seal to the medium is metallic, the seal of the valve spindle is a gland packing. The valves blocks are available in the following versions: -fold valve block -fold valve block, flanging on both sides 5-fold valve block The mounting is carried out via integrated threaded connections and a bracket existing on site. The mounting with -fold valve block for mounting on both sides is made vial integrated flanges with threaded connection to the orifice. Rust, sand or similar pollution in the medium can build up around the valve seat, especially when the system is flushed out before the first setup. This can cause leakage around the valve seat. The spindle must therefore be fully opened to permit flushing out. When the prepressed packing is stored for a longer time, its sealing ability can deteriorate. If necessary, the seal must be retightened at the time of setup. The procedure is described in chapter "Maintenance and fault rectification".
