Features

Rugged Design - Die-cast aluminum case and cover can withstand impacts that would fracture the plastic cases of our competitors

Wide Range of Bourdon Tubes - Pressure ranges from 0-30 psig to 0-3000 psig are available. Two interchangeable ranges of output bellows and gauges (3-15 psi and 6-30 psi) are also available

Simple Adjustments - High-visibility dials are provided to assure accuracy of pressure setpoint, proportional band, and reset settings

Easy Maintenance - Simple controller design allows fast, easy maintenance and minimal spare parts inventory

Field Reversible - Switch controller action with a few simple steps. No additional parts required

Easy Mode Conversion - Add reset action to a proportional controller by simply adding a single module and three pieces of tubing

Flexible Mounting Options - Available with brackets for mounting on actuator yoke, diaphragm housing, panel, surface, or 2-inch pipestand

Vibration Resistance - Simple design and low mass of internal parts allow the controller to withstand vibration encountered in most industrial environments

Low Air (Gas) Consumption - Relay and nozzle design reduces steady-state air (gas) consumption to as low as 4.2 scfh, cutting operating costs

Sour Service Capability - Materials are available for applications handling sour gases. These constructions comply with the recommendations of NACE MR-01-75
