Chart Recorders

At Twinco Industrial, our chart recorders are built for accuracy and durability in demanding environments. They help operators verify test integrity, detect fluctuations, and maintain compliance with safety and documentation standards. Available in single- or dual-pen configurations, our recorders are ideal for hydrostatic testing, pipeline commissioning, and pressure validation applications.

Every valve we supply is designed for dependable shut-off and control. We source our valves from reputable manufacturers who test each unit for seat leakage, shell strength, and operational cycle count. Whether you need a manual valve for simple on/off service or an actuated valve for automated process control, we can provide the right solution. Our range includes various end connections (threaded, socket weld, butt weld, flanged) and trims to handle everything from water and steam to aggressive chemicals and hydrocarbons.
