Overall dimensions and technical information are provided solely for informative purposes and may be modified without notice 85 VALVES AND SOLENOID VALVES Valves and solenoid valves poppet system Series 700 Valves and solenoid valves poppet system for vacuum applications with high flow rates. These are manufactured only in 3/2 and 2/2 versions, either normally closed or normally open. Selection of the right type and connection to the pump requires some knowledge and skill.

They do not need to be lubricated to operate well, but good filtration is recommended to prevent dirt accumulation inside. Ensure that the conditions of use are consistent with the indicated limits, pressure, temperature, etc. Take care to protect the discharge outlets of the valves in the presence of dirt and powder. When the self feeding version is used in the solenoid valves, check that the supply flow rate is greater than or equal to that of use, otherwise switch to the version with external pilot. The ordering codes refer to solenoid valves with “M2” or “M2/V” mechanicals mounted. The solenoid coils are not included and have to be ordered separately (see summary page for solenoid coils).Certified solenoid coils are also available For electrical actuation a normal M2 microsolenoid is used in the case of control via air and a special M2/V microsolenoid is used when control is via vacuum.
