ASCO 551-553 Solenoid Valves NAMUR – 1/4 – 1/2 Stainless Steel 15/16 Pilots TUV Exida Approved Pilot Valve

ASCO 551-553 Solenoid Valve - Pilot Operated Valve

ASCO 551-553 Solenoid Valve – Pilot Operated Valve

ASCO 551-553 solenoid valves are 3/2 way internal/external pilot operated solenoid valves.

ASCO 551-553 Solenoid Valves features

  • Brass and stainless steel solenoid valve types
  • 3 way solenoid valve with orifice and pipe connections in body
  • The valve offers environmental protection against the ingress of liquids, dusts or any other foreign matter (environmentally-protected construction)
  • Can be externally piloted (external air pilot supply) to convert valve to zero minimum operation by flipping a gasket
  • Differential Pressure : 0 / 0,7 – 10 bar [1 bar = 100kPa]
  • Flow (Qv at 6 bar) 1/4 = 860 l/min (ANR) 1/2 = 3000 l/min

ATEX & IECEx valves are available using ASCO 551-553 solenoids approved to EN 13463-1 for hazardous area applications.

SOLENOID VALVES

EXPLANATION OF TEMPERATURE RANGE

Valve Temperature Range : the temperature range (TS) of the solenoid valve is determined by the selected sealing material, the temperature range for proper operation of the valve and according to the fluid (eg steam).

Operator Ambient Temperature Range : determined by power level and safety code.

Total Temperature Range : the total temperature of the solenoid valve is determined by both the limitations of the above.

ASCO 551-553 solenoid valves are available with NAMUR interface. NAMUR, translated from the German acronym to StandardiSation Association for Measurement and Control in Chemical Industries, is the specification for a standard interface between pneumatic actuators, solenoid valves and directional control valves.
