2/2-Way Miniature Solenoid Valve Type 201 Advantages/Benefits Normally closed Body material: brass Short response times Compact design

Applications

  • Neutral gases and liquids
  • Pneumatic control
  • Vacuum
  • Shut-off, dosing, filling and ventilating
  • Small scale devices, laboratory and measuring technology
  • Gas control, welding technology Design/Function Type 201 is a normally-closed direct-acting plunger-type solenoid valve. Direct-acting, Sub-base When energized, the solenoid ar- mature is drawn in against a spring to open the valve. The solenoid epoxy encapsulation efficiently dis- sipates the heat generated by the coil. Fluid Control Systems

Installation / Accessories Operating Data (Valve) Operating Data (Actuator) Technical Data Circuit Function A 2/2-way valve, normally closed Seal Materials/Fluids Handled/Temp.- Range NBR Neutral fluids, e.g. compressed air, town gas, water, hydraulic oil -10 to + 90 °C FPM Hot air, oxygen, per-solutions, hot oils, oils with additves -10 to +100 °C For more detailed information please refer to resistance chart (Leaflet-No. 1896009). Max. ambient temperature +55 °C Max. viscosity approx. 21 mm 2/s Response times opening 5 - 18 ms closing approx. 8 ms Times measured at outlet A from switching on until pressure rise to 90 % / pressure drops to 10 % at a max. working pressure of 6 bar.

Installation as required, but preferably with solenoid system upright Electrical connection • plug connection without cable plug (supplied as standard)

  • moulded-in cable on request
  • 2 or 3 moulded-in flying leads on request 1) Measured with 6 bar upstream pressure and 1 bar pressure drop across the valve at +20 °C., 2) Also suitable for vacuum. Type 2012/2-Way Miniature Solenoid Valve

The manifolds for 1 to 6 valves have a common pressure inlet and individual outlet for each valve. Type 201 may also be mounted together with Type 301 valves (circuit function C, de-energized, outlet A exhausted) on the same manifold. The electrical connection can be either to the right or left of the manifold. Manifolds may be coupled together using special push- fit O-ring connecting nipples for linking the pressure inlets P. Manifolds joined together in this way should be securely mounted.
