2. When operating the mechanical operation type mechanical valves, select the angle and the maximum speed limit of cam and dog so that valves do not operate over the following maximum values. If operated over the maximum values, impact force from cam and dog will be applied to the actuator, leading to damage of the actuator or the valve itself. Cam and Dog Series Actuator type Angle limit of cam and dog Max. speed limit of cam and dog (m/s) VM100 Roller lever 30° 0.7 45° 0.3 One way roller lever 30° 0.7 45° 0.3 Straight plunger . 0.2 Roller plunger 30° 0.3 Cross roller plunger 30° 0.3 VM200 Roller lever 30° 0.7 45° 0.3 One way roller lever 30° 0.7 45° 0.3 Straight plunger . 0.2 Roller plunger 30° 0.3 Cross roller plunger 30° 0.3 Over 45° (Abrupt angle) 45° or less [Not acceptable] [Acceptable] Max. travel Over travel. Excessive force is applied due to the maximum travel position being exceeded. Sufficient travel. The actuator can reach the total travel position without excessive force being applied. Max. travel [Not acceptable] [Acceptable] Cam and Dog Material Roller material Cam and dog material Surface finish of cam and dog Polyacetal Steel 6.3 z or less Hard steel Steel, Resin 25 z or less Caution 1. If the operating condition is maintained for long periods of time, it may take some time for the valve to restart due to the adherence of the seals and there might be a delay for recovery. Air Supply Warning 1. Operable fluid is either air or inert gas only. It cannot be used for corrosive gas and fluid. Caution 1. Grease is used for the inside of the valves. Grease may enter into the outlet port of the valve. 2. When using vacuum pressure for the VM100, supply vacuum pressure to P port. Operating Environment Warning 1. Do not operate it in an area in which fluids such as oil, coolant, or water splash on it or dust comes in contact with it. Because it does not have a waterproof or dustproof construction, fluids or dust could enter the valve, leading to malfunction. Therefore, take measures such as providing a protective cover to prevent direct exposure. 2. Do not expose the product to direct sunlight for an extended period of time. Maintenance Warning 1. Perform inspections on a regular basis as necessary, such as at the beginning of an operation, to make sure that the mechanical valve operates properly. 2. Do not disassemble, modify or repair the product. This may lead to malfunction of equipment, injury and equipment damage. Please contact SMC for repairs and maintenance of the product.
