Description:ITV1050-312L Electro-Pneumatic SMC Electronic Vacuum Pressure Regulator Item Specifics:Power Consumption: 4W or lessWorking Temperature: 0 ~ 50 ℃ Feature:1. Stepless control of air pressure proportional to an electrical signal2. IVT1000/2000/3000 series are compatible with various input specifications, Including serial communications.3. Compact/lightweight (Integrated communication parts) Working Principles:When the input signal rises, the air supply solenoid valve ‘1’ turns ON, and the exhaust solenoid valve ‘2’ turns OFF. Therefore, supply pressure passes through the air supply solenoid valve ‘1’ and is applied to the pi-lot chamber ‘3’. The pressure in the pi-lot chamber ‘3’ increases and operates on the upper surface of the diaphragm ‘4’.As a result, the air supply valve ‘5’ linked to the diaphragm ‘4’ opens, and a portion of the supply pressure becomes output pressure.This output pressure feeds back to the control circuit ‘8’ via the pressure sensor ‘7’. Here, a correct operation functions until the output pressure is proportional to the input signal, making it possible to always obtain output pressure proportional to the input signal. Package Included:1 x Electro-Pneumatic Regulator
