The valves series 1134 ; 1138 ; 1140 ; 1148 ; 1150 ; 1158 ; 1164 ; 1168 ; 1170 ; 1178 ; 1190 ; 1198 are normally open valves. NO = when the coil is de-energised the plunger opens the valve seat connecting the inlet to the outlet, when the coil is electrically energised the plunger stops the fluid flow. The NO valves are supplied only without coil (S type). N.B.: the NO valve visually differs from the corresponding NC model by means of the red ring installed below the yellow nut that fastens the coil.
The valves series 1164 ; 1168 ; 1170 ; 1178 (excluded /11 , /13 , /M42) ; 1190 ; 1198 (excluded /9) are diaphragm pilot operated valves.
The valves series 1134 ; 1138 ; 1140 ; 1148 ; 1150 ; 1158 ; 1178 (/11 , /13 , /M42) ; 1198/9 are piston pilot operated valves.
The solenoid valves, shown in this chapter, are classified “Pressure accessories” in the sense of the Pressure Equipment Directive 94/23/EC, Article 1, Section 2.1.4 and are subject of Article 3, Section 1.3 of the same Directive. They are designed for installation on commercial refrigerating systems and on civil and industrial conditioning plants, which use the following refrigerant fluids: R22 , R134a , R404A , R407C , R410A , R507 proper to the Group II (as defined in Article 9, Section 2.2 of Directive 97/23/EC and referred to in Directive 67/548/ EEC). For specific applications with refrigerant fluids not listed above, always proper to the Group II, please contact Castel Technical Department.
