Valves according to their maximum working or design pressure - This is the maximum pressure the valve will see during normal working conditions. Solenoid valves and actuated valves can be chosen according to their maximum design working pressure such as vacuum, 1 bar, 6 bar, 10 bar, 15 bar, 20 bar, 30 bar, 40 bar, 50 bar, 80 bar, 100 bar and pressures exceeding 100 bar up ro 500 bar.
Helpful hint: If you cannot find the valve you need try the next pressure range up. i.e. for a 9 bar valve try also 10 bar (150psi) and 15 bar (225 psi) rated valves and look at related products on this actuated valve store.
