EQUILIBAR”s NL Series backpressure regulator provides precision better than 1/4” water column. With no moving parts, the frictionless design controls process pressure to within 1 percent to 2 percent of setpoint over flowrates ranging from 1-to-1000. By using a fluid reference signal to communicate the setpoint to the device, the pressure regulator delivers hands-off precise flow control for automated process streams. The pressure regulator is available from 1/4” through 1.5’ NPT in SS316, PTFE, PVC, and other materials.
