Compact, reliable PTFE Needle Valves are designed for use in laboratory and industrial applications for regulating corrosive gases and liquids or for high purity service. In addition, these low flow rate regulators can be used in pressure or non-critical vacuum service and as shutoff valves. (read more)

Now there's a compact I/P transducer that delivers reliable high performance for the toughest applications in the most hazardous environments: the Type 950XP from ControlAir.The 950XP converts an electrical current signal to a stable, pneumatic output to actuate valves. Its NEMA 4X (IP65) housing is designed for both Intrinsically Safe* and Explosion-Proof* operation. (read more)

The Type 890 Series Baratron® compact digital pressure transducers utilize an advanced digital microprocessor to produce exceptional stability, the lowest output drift on the market, and high accuracy up to 20 times better than conventional pressure transducers. (read more)

The Laureate Model VF is a UL-listed, programmable 6-digit panel meter which can display rate or totalized rate from transducers with a 4-20 mA, 0-1 mA or 0-10V output. Readings can be scaled to engineering units such as gallons per minute or gallons. Square root extraction is standard for use with differential pressure flow sensors and is applicable to rate or total. (read more)

Model AFM Mass Flow Meters are designed to indicate flow rates of gases. Each of these units incorporates an advanced straight tube sensor in conjunction with flow passage elements constructed of stainless steel. LED readouts of command modules are supplied with 0 to 100 percent calibrations.
