VALVES & FLOW CONTROL MULTI-PORT VALVE BLOCKS
GEMÜ
Dosing Installations for Detergent in Industrial Laundries : Extendable GEMÜ Plastic Multi-port Valve Blocks
In a successful industrial laundry applications , the GEMÜ plastic multi-port valve blocks are used to produce a wide variety of detergents and automated systems for dosing these detergents . The compact GEMÜ plastic M-Blocks are the key element in these systems as they make the corresponding dosing , distribution and flushing functions possible .
OPERATION OF DETERGENT DOSING INSTALLATIONS
Automated detergent dosing installations provide industrial laundries with flexibility , allowing them to adjust the required detergent composition individually to each specific cleaning programs . Depending on the hardness of the water and the type and level of soiling , the cleaning agents , special additives and care products can be dosed to match the type of textile being washed .
In the case of conventional dosing installation designs , a separate dosing pump is required for each washing machine and medium . The resulting large number of pumps , hoses , unions and distribution components makes extensive maintenance and calibration work necessary .
COMPACT DESIGN IMPROVES PLANT RELIABILITY
The use of GEMÜ multi-port valve blocks allows the number of pumps , hoses and fittings to be kept to a minimum on modern dosing installations . Only one pump is required per medium and multiple washing machines can be supplied with

one dosing installation . A smaller number of connection points improves plant reliability as it reduces both potential leakage points and deadleg . Less connections mean less time required to assemble the customized units . All these benefits make a significant contribution to cost optimization of the plant .
MULTIPLE FUNCTIONS IN ONE MULTI- PORT VALVE BLOCK
In order to achieve a more compact design , all dosing , distribution and flushing functions are combined in one multi-port valve block . The dosing pump for each medium is connected to a variable area flowmeter each of which is connected directly to the multi-port valve block . The valve block consists of 3 rows of pneumatically actuated diaphragm valves . The first valve row at the bottom is used to dose the medium . Depending on the requirements , quantities of 10 – 200 ml are metered out . The valves in the second row control which washing machine the medium is sent to and the upper , third row of the valve block is used to flush the unit with water after every dosing process .

EXPANDABILITY OF EXISTING PLANTS
The multi-port valve blocks are also able to be extended . If an industrial laundry adds washing machines to its plant , the existing dosing unit can be extended by the required number of valves with just a few simple modifications without the need for additional piping , solvent cemented joints or welds .
