The Subminiature Pressure Regulator (M70) is made of brass and zinc plated steel construction and it has vibration damper. The repeatability within 0.06 PSIG is already dead ended. The advantages of using the product is it permits deployment in private spaces and allows the use of corrosive or difficult environments. The product grants a small noise operation and it promotes highly precise setpoint control. The products can handle a 250 PSI and it has maximum supply pressure of 17 bar and provides five (5) set point pressure ranges from 0-5 psi, 0-3.5 BAR, 0-35 kPa up to 2-100 psi, 0.1-7 BAR, 15-700 kPa. 70220, 70230, 70240, 70250. The product features control sensitivity of 2.5" water column and a supply pressure effect of less than 1% to convey steady and stable precision efficiency to preserve the desired set point regardless of supply pressure changes or conditions.
