General Terms This operating manual has to be read carefully and observed by the competent operating and maintenance personnel. We have to point out that we will not accept any liability for damage or malfunctions resulting from the non-compliance with this operating manual. -
Page 8: Mode Of Operation
Mode of Operation Double seal change-over valves DELTA SDU4 have been developed for the use in the brewing and beverage industries, in Control Unit dairy and food applications as well as for the chemical and Delta CU21N pharmaceutical industries. position The field of application of the DELTA SDU4 comprises the safe indicator shut-off and change-over of line sections. -
Page 9: Auxiliary Equipment
Auxiliary Equipment - Valve position indication A proximity switch holder for the valve position indication can be installed direct on the actuator. With SDU4 valves being equipped with valve position indication it must be observed that the max. closing pressure is reduced compared with the valve design being equipped with the control unit DELTA CU21N. -
Page 10: Cleaning
Cleaning For the cleaning of SDU4 valves distinction is made between two areas. - The flow chambers The passages of the valve are cleaned by the cleaning liquid during the cleaning of the connected pipelines. - The leakage chamber The cleaning of the leakage chamber is undertaken via the leakage valves.The cleaning liquid is supplied via one leakage valve and discharged to the atmosphere via the second leakage valve. -
Page 11: Installation
Installation Installation has to be done in such a way that fluids can drain off the valve housing and is preferably to be realized in vertical position. To provide for the dismantling of the valve insert, the valve housing ports of the upper and middle housing balls must be connected in a detachable manner by a flange or clamp connection. -
