Product catalog summary
Overview: This document provides technical specifications and performance details for a 2/2-way solenoid valve with a nominal diameter of DN 21, designed for use with cold and heated potable water and similar media. The valve is servo-controlled and normally closed (NC).
Specifications:
  • Material: Valve body made of brass CW617N, plunger guide and spring made of stainless steel, membrane and sealings made of EPDM (NBR available on request).
  • Coil Coating: Options include PBT, PET, or epoxy resin.
  • Function: Normally closed (NC), suitable for hot water up to 90°C.
  • Operating Pressure: 0.3 - 10 bar.
  • Cv-value: 67 l/min.
  • Nominal Voltages: Available in various AC and DC voltages, with a tolerance of +10% to -15%.
  • Duty Cycle: 100% continuous duty.
  • Protection Type: Ranges from IP00 to IP68.
  • Insulation Class: F according to EN 60730.
  • Protection Class: I according to EN 60730.
Applications: The valve is suitable for a wide range of applications including steam appliances, dental appliances, hot/cold drink dispensers, industrial appliances, air conditioning, agricultural implements, pollution equipment, temperature equalizers, dishwashers, ice machines, washing machines, and water treatment systems.
Performance Features:
  • Optimized for low noise emission according to EN 60730, reducing water hammer effects.
  • High operating safety ensured by high-quality materials and 100% final testing.
  • Solenoid is replaceable without affecting the medium circuitry.
Dimensions: The valve is available with various inlet and outlet dimensions, all with a length of 90.0 mm, height of 96.0 mm, and depth of 45.0 mm.
Coil Types: Available coil types include MS.006, MS.024, and MS.025, with different protection ratings (IP00, IP65, IP67, IP68).

servo-controlled normally closed (NC) solenoid replaceable while medium circuitry remains untouched suitable for hot water up to 90 °C similar performance for alternating- or direct current long term performance capability optimized water hammer characteristic by low noise emission according to EN 60730 high operating safety by the use of high quality materials and 100% final testing of the products steam appliances dental appliances hot / cold drink dispensers industrial appliances air conditioning agricultural implements pollution equipment temperature equalisers dish washers ice machines washing machines water treatment 2/2-way solenoid valve of nominal diameter DN 21 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 single chamber straight valves with female thread at in- and outlet in different dimensions. Coil systems for common voltage frequency ranges are available. and typical performance curve Electrical operating safety is achieved by insulation class F and can be supported by an integrated protective circuit. By using high quality insulation materials, continuous duty (100 % ED) at higher medium temperatures is possible. Protection against corrosion of inner parts exposed to the medium is achieved by using stainless steel. p / bar © copyright A.u.K. Müller, technical changes reserved
