Pressure control with dual valve control is here, ideal for closed volume applications. Alicat's PCD series allow for stable and response control. Gas wastage is reduced as there is no continuous bleed valve, instead a second independently controlled exhaust valve that actuates only when the pressure needs to be reduced.
The PCD dual valve pressure controller is available for both gauge and absolute pressure applications and offers a maximum pressure rating of 35 bar. A differential model is also available for DP's of up to 10 bar.
