eries -IV/ Construction Knob djusting spring tmospheric intake valve Vacuum chamber q Diaphragm tem tmospheric chamber Valve w E Working principle When the knob is turned to the right (clockwise), the adjusting spring s generated force pushes down the diaphragm and the valve. his connects the side and E side, and the degree of vacuum on the E side increases (becomes closer to an absolute vacuum). Furthermore, the E side vacuum pressure moves through the air passage into the vacuum chamber, where it is applied to the top side of the diaphragm and counters the adjusting spring s compression force; and this adjusts the E side pressure. When the degree of vacuum on the E side is higher than the designated setting value (becomes closer to an absolute vacuum), the balance between the adjusting spring and the E side pressure in the vacuum chamber is lost, and the diaphragm is pushed up. his causes the valve to close and the atmospheric intake valve to open, which lets atmospheric air into the E side. When the adjusting spring s compression force and the E side pressure are balanced, the E side pressure is set. lso, when the degree of vacuum of the E side pressure is lower than the designated setting value (becomes closer to the atmosphere), the balance between the adjusting spring and the vacuum chamber is lost, and the diaphragm is pushed down. his causes the atmospheric intake valve to close and the valve to open, which lets air into the side. When the adjusting spring's compression force and the E side pressure are balanced, the E side pressure is set. eplacement Parts No. Description 1 Diaphragm assembly 2 Valve assembly Material HN, etc. Part no.

eries -IV/ pecific Product Precautions e sure to read this before handling. efer to Handling Precautions for MC Products (M-E03-3) and the Operation Manual for afety Instructions and Precautions. Please download the Operation Manual via our website, http://www.smcworld.com/ Warning Handling 1. When a system hazard can be expected due to a drop in vacuum pressure caused by power loss or vacuum pump trouble, install a safety circuit and configure the system so that it can avoid the danger. 2. When a system hazard can be expected with trouble with the vacuum regulator, install a safety circuit and configure the system so that it can avoid the danger. Warning Operating Environment 1. Do not use in an atmosphere having corrosive gases, chemicals, sea water, water, water steam, or where there is direct contact with any of these. 2. Do not use in locations influenced by vibrations or impacts. 3. his vacuum regulator always uses atmospheric air, therefore, do not use in dusty environments. 4. In locations which receive direct sunlight, provide a protective cover etc. 5. In locations near heat sources, block off any radiated heat. Caution Vacuum upply 1. his vacuum regulator is not to be used for adjusting vacuum pump pressures. 2. Note that an ejector s flow rate is smaller than that of the vacuum regulator, and therefore, it is not suitable as a vacuum supply. Caution upply 1. hese products are designed for use with air. Please contact MC if any other fluid will be used. 2. Do not use air which includes chemicals, synthetic oils containing organic solvents, salt, or corrosive gases, etc., as this can cause malfunction. Caution -IV Zero position -IV Precautions 1. Connect piping to the port with indication for connection to the vacuum pump. 2. o adjust the pressure, turn the knob to the right (clockwise) for changing atmospheric pressure to vacuum pressure and to the left (counterclockwise) for changing vacuum pressure to atmospheric pressure. 3. When adjusting pressure, do not touch the lateral hole (atmospheric intake hole) of the body. 4. When locking the knob after setting the pressure, press down the knob until the orange band is hidden and a click is heard. On the other hand, when unlocking the knob, pull it up until the orange band is visible and a click is heard. 5. his vacuum regulator is for use with vacuum pressure only. e sure that positive pressure is not applied instead. In the event that positive pressure is applied, the vacuum regulator will not be damaged. However, the main valve of the pressure adjustment valve will open and positive pressure will enter the vacuum pump. his may cause trouble with the vacuum pump.. When the vacuum pump capacity is relatively small or when the inside diameter of the piping is small, a change in the set pressure (the pressure difference between the non-flow and flow conditions) may be large. In this case, change the vacuum pump or the inside diameter of the piping. When changing the vacuum pump is not possible, add a capacity tank (the capacity depends on the operating conditions) to the side. 7. he pressure response time after opening and closing of valves (such as solenoid valves) is influenced in large and small measures by the internal capacity (includes piping capacity) of the set side. ince the vacuum pump capacity also affects the response time, consider all these points before operations. 8. When using a pressure gauge upside down like Fig. 1, it may result in a shifting of the zero point reading. Make sure to use it in the direction like Fig. 2.
