Solenoid valve NC, DN 7 two chambers in line

2/2-way solenoid valve of nominal diameter DN 7 for use with cold and heated potable water and physically and chemically similar media. The valve is servo-controlled and normally closed (NC).

Valves of this design are 2-chamber valves with the inlet ninety degrees to the outlet. The two chambers operate simultaneously to increase functional reliability. The function is similar to the assembly of two single valves in line. These valves can be manufactured with various connections.

Coil systems for common voltage and frequency ranges are available.

Electrical operating safety is achieved by insulation class F and can be supported by integrated protective circuits.

By using high quality insulation materials, continuous duty (100 % ED) at higher medium temperatures is possible. The glass fibre reinforced polyamide valve body persists hot water. Protection against corrosion of inner parts exposed to the medium is achieved by using stainless steel.
