The VRP-SB-CH provides pressure control when utilized with a single-acting actuated control valve. The VRP-SB-CH measures process sensing pressure and positions the single-acting actuator to maintain the pressure setpoint.  The VRP-SB CH Pilot may be utilized for pressure control applications with set points ranging from 1.0 psig to 1300 psig (6.9 kPa - 8964 kPa). The VRP-SB-CH features ZERO steady state bleed and may incorporate Dresser's unique Bleed to Pressure System (BPS)™ capability to completely eliminate atmospheric emissions.
