2 Series PV 6 Spring loaded full lift safety valve d, with open bonnet Application The safety valve Series PV 6 is certified as Safety device for protection against excessive pressure according to N ISO 6- standard. The valve is determined for steam, air and other gases. Chemical composition of medium must be in accordance with material of valve's body and inner parts. Working temperature range is from +5 C to +00 C, if the temperature is higher than +350 C, the execution with cooling is recommended. The valve's discharge capacity, based on the data given in this sheet (A 0, K dr), is guaranteed, if the pressure drop in inlet pipeline doesn't exceed 3% of p set and simultaneously the pressure drop in outlet pipeline doesn't exceed % of. Design The safety valve Series PV 6, is manufactured in pressure ranges, sizes and executions according to following tables. The tables contain the detail information about the dimensions, weight, range of set pressure and material of main parts too. For PN and PN0, the valve's body is casted, the inlet nozzle is it's integrated part. The seat ring is tightly pressed into it. For PN63 and PN00, the casted body is provided with forged inlet nozzle with integrated seat. The 's dimensions are according to N 0-, respectively to N 0-. The flat disc is equipped with lifting bell, which is exposed to pressure of medium when the valve starts to open. The opening force is increased by this way, the result is quick opening of valve. p set The spring, which causes the closing/sealing force, is designed for specific range of set pressures, the fine setting is made through adjusting screw. The valve is equipped with lever, which serves for manual valve opening/test of function under the normal operating conditions of protected equipment. Installation instructions ) The valve should be installed with spindle in vertical position ) Outlet line must be inclined, the drainage hole must be provided in the lowest point 3) On demand, the valve's body can be manufactured with drainage hole Ordering The full type number must be given when ordering the valve. Demand for other s than according to N 0 or for position sensor must be placed in order too. The counter s, gaskets and bolts/nuts can be provided on demand too. --
