5 14 REGOLATORI AUTOAZIONATI DI BASSA/MEDIA/ALTA PRESSIONE A SINGOLO STADIO SINGLE STAGE LOW/MEDIUM/HIGH PRESSURE SELF-DRIVEN REGULATORS Mod. DIVAL INTRODUZIONE INTRODUCTION Pressure reguiators DIVAL series are spring loaded regulators with balanced plug, diaphragm command and contrast action by spring, suitabie for low, medium and high pressures. Divals and shut-off device series regulators are supplied with internal sensine line. Both regulator and shut-off device are preset for connection to an external sensine line by the customer, related to flowrate diagram on next page. They aro widely used either in civil or industriai plants, usino Natural gas or LPG or non corrosive gas. Thanks to the concept of balanced plug to achiave a: - high flow rate coefficient; - high accuracy, even at maximum flow rates; - reduced lock up pressure zone and lock up pressure; - reduced response times; - no internal leakage at nui flow rate; - fail to open type; - periodical maintenance without disassembling the body from pipings; - possibility to incorporate the slam-shut (OPSO/UPSO) even on reguiators aiready installed, withuot modifying the existing pipings.

11 Mod. LA INTRODUCTION The mod. LA shut-off valve or pressure switch valve is a safety device wdich may be applied to the regulation equipment as all regulators of DIVAL SERIES and to the shut-off equipment as the DILOCK valves. The task of the shut-off valves is to interrupt the gas flow, through an external plug, each time a danger situation occurs. Their operation is related with the connection to a point for the monitoring of the pathway, generally downstream the equipment of regulation or shut-off. - : 2 (- C + 60 C). - Ma : PS bar /4 F. - 1/8 F ISO standard per DIVAL , : /190 C. 97/23 CE PED MAIN FEATURES - Temperature class: 2 (- C + 60 C) - (-4 F +140 F). - Maximum pressure admitted in the external safety plug system: PS bar - PS 290 Psi. - Safety plug with By-pass to make easier the reset with high feeding pressures. - Reset is solely manual (except for the intervention in case of Temperature increase). - Cap with possibility to check the seal for any violation. - Reading pressure inlet with thread 1/4 F with filter. - Remote connection of the cover exhaust of the measuring device with thread 1/8 F ISO 2. - Test button - standard for DIVAL 160 and 250, 5 and Pre-arrangement for electric contact to signal the intervention in telesurveillance (upon request). The device operates in the following cases: - OVER PRESSURE - in case the monitoring pressure exceeds the calibration limits. (the calibration changes from the outside according to the range forecast by the spring in use). - UNDER PRESSURE - in case the monitoring pressure goes below the calibration limits (the calibration changes from the outside according to the range forecast by the spring in use). - TEMPERATURE INCREASE - in case the valve temperature goes further 170/190 C - 338/374 F.
