Type 6227 Servo-Assisted 2/2-Way Modular Water Valve System

The servo-assisted solenoid valve with servo diaphragm is normally closed (NC). In this condition, pressure builds up above the diaphragm - the valve holds tight. When energized, the space above the servo diaphragm is pressure relieved and lifted up by the medium - the valve opens. The modular extendable valve system can be built up in all possible combinations with up to 12 valves each as distributor or collector in two sizes with different port connection modules. 

The valve can be put together in collecting function or distributing function by easily twisting the valve insert. Any combination of functions in one block is possible. Additional functions such as temperature indication or flow measurement can be added by integrating a corresponding sensor directly into the valve block. In order to be as flexible as possible, a variety of port connections are available as standard. 

The inner thread port connections are at the bottom, pointing down while the outer thread port connections and the plug-on connection for hoses are pointing to the side. The block material is Polyamide glass fiber reinforced. The advantages are: Low weight and a certain chemical resistance.
