Precision pressure regulator IR series 

Precision pressure regulator IR series   Pressure Control Equipment Electro-Pneumatic Regulator controls the pneumatic valve by electrical signal to adjust the air pressure, while the Precision Regulator realizes the air pressure regulation by mechanical manual adjustment of the valve. The Electro-Pneumatic Regulator usually has a large adjustment range and can achieve a higher pressure change, while the Precision Regulator has a relatively small adjustment range and is usually used in applications requiring higher precision.
