ASCO 551 Solenoid Valves NAMUR – 1/4 – Aluminium 3/2 – 5/2 Pilot Operated 40°C Pilot Valve

ASCO 551 Solenoid Valve – Pilot Operated Valve

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

ASCO 551 Solenoid Valves features

The NAMUR version has all ports on the same side and with the same threads for a better resistance to water, dust and better fitting connection
The solenoid valves exist with all protection mode: Ex d, Ex e mb, Ex m and Ex ia
Can be externally piloted (external air pilot supply) to convert valve to zero minimum operation by flipping a gasket
The ASCO 551 solenoid valves exist with all protection mode: Ex d, Ex e mb, Ex m and Ex ia
Differential Pressure : 2 – 10 bar [1 bar = 100 kPa]
Flow (Qv at 6 bar) 1/4 = 700 l/min (ANR)

ATEX & IECEx valves are available using ASCO 551 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.
