Introduction

Generally used for liquid cargo ships, carrying propylene oxide class can load ordinary chemicals. When the loading of the ship propylene oxide class of goods, as long as the CF-ISO-pressure valve is forced to close can the contrary, such as the load of ordinary chemicals, simply open the forced shut-off device . Before loading and unloading shall be the operational requirements of the valve lift check. Inspection, you must also check the pressure valve and vacuum valve of the two valves, the role of mutual insurance, because the use of two valves can prevent the cargo hold over pressure and pressure loss. According to the flow range of the DF type pressure/vacuum valve can be installed in DN125 (including DN125) following ventilation tube, the connection flange is optional by the user.
