VALVES AND SOLENOID VALVES Overall dimensions and technical information are provided solely for informative purposes and may be modified without notice 87 Valves and solenoid valves poppet system Series PG Valves and solenoid valves poppet system for vacuum applications with high flow rates. They are manufactured in 3/2 and 2/2 versions, both normally closed and normally open. There is an additional seal on the piston which isolates connection 3 from the piloting, allowing the normally open and vacuum self-powered versions (not Konstruktionsmerkmale G 1/2“ - 1/2“ NPT G 3/4“ - 3/4“ NPT G 1“ - 1“ NPT G 1 1/2“ - 1 1/2“ NPT Body, operator and end cover Aluminium Actuators rod Steel Bottom plates Aluminium Seals and poppets NBR Springs Stainless steel Pin guide Stainless steel Pistons Acetal Resin These valves have a mean life of 10 to 15 million cycles under normal operating conditions. Lubrication is not required for good operation but we recommend good filtration to avoid dirty deposit causing malfunction. Please ensure that the valve is being used according with the manufacturers specification, such as air pressure and temperature. the exhaust port of the distributor has to be protected in a dusty and dirty environment. For these products, according to the construction technique and special application, is not required any maintenance with parts replacement. When necessary it is sufficient to clean the internal parts. When it is used the solenoid valves with internal pilot, inlet flow rate must be equal or higher that the required consumption flow rate. Otherwise is better choose the external pilot version. available in the previous series for sizes G1/2“ – G3/4“ – G1“) Body and operators are made of die-cast aluminium and processed with protective epoxy paint.
