About
The Pressure Reducing Electric Valve is a pneumatic automation equipment unit that both opens/closes a high-pressure gas line and reduces pressure from high to low while maintaining low pressure within a specified range. It handles propellant flow rates of 0.036 to 9 kg/h and reduces inlet pressure from up to 350 kgf/cm² to 4.5 kgf/cm² outlet. Operating temperature is -40 to +50 °C, supply voltage 27 V DC. Released in 1985 with a 12-year guaranteed service life and 10.5-year active lifetime, delivered in 9 months.
