Flow Controllers

Remote Operations Controller measures up to 12 meter runs.

Model ROC809 combines Remote Terminal Unit (RTU), Flow Computer, and PLC capabilities. Gas flow calculations use AGA 3 for orifice metering, AGA 7/ISO 9951 for turbine metering, and AGA 8/ISO 9951 for compressibility. PID loop control is configurable for up to 16 control loops. Up to 6 Function Sequence Table (FST) controls let users develop control strategies using logic, math, comparison,...

Flow Controllers

Pneumatic Fittings simplify motion control.

Blocking fittings mount on air cylinder port and use independent pilot air signal to block movement of piston rod at selected positions. Slow Start fittings control speed at which cylinders recover position. Flow Control Regulators are unidirectional and adjust speed of cylinder rod by controlling inlet or outlet flow. Inline Flow Controls mount anywhere and can be ganged together. Right Angle...
