Pneumatically operated valves rely upon compressed air to operate. Their purpose is to stop or redirect air in a circuit. Many of the products available are suitable for a number of media, including compressed air, water and oil. They are available in three main states: bistable, monostable and normally closed; with 2/2, 3/2 and 5/2 connection options. Flow rates are from 150 l/min to 780 l/min with operating temperatures of -10 to +60 °C. Operating pressures vary from 0.5 MPa to 1 MPa. There is a full range of connection options including G1, G1/2 and G3/4 for both the control air and termination connections, allowing for integration into an existing pneumatic circuit. There is also a comprehensive selection of accessories including mounting brackets, fastening plates and compressed air tubing available to complete an installation. If required, these can be ordered separately. The majority of products in this range are manufactured by SMC.
