The sensing technology is versatile and compatible with any metering valve design, according to the company.
The hopper shuttle system can more than double productivity by allowing one hopper to be filled and discharged while the other hopper and metering valve are cleaned, according to the company.
Since a metering valve was used, its installation and instrumentation could have resulted in additional flow losses downstream the valve and before entering the refrigerant distributor at the evaporator inlet.
The MD Series of rotary feeder valves provides those involved in bulk material handling process engineering, production supervision and equipment maintenance with a material metering valve that immediately contributes tangible operating efficiency advantages, long-term production and maintenance savings.
Vertical lifting and positioning is accomplished with compressed air that is operator controlled with a pistol grip metering valve. Optionally, an ergonomic twist grip controller with precision bearings minimizes vertical movement resistance.
The lifter does not require an air lubricator, and includes a pistol grip metering valve control for vertical lift.
The metering valve is integrated into the outlet of the hopper and has a self-closing mechanism to prevent material flowing out when the hopper is removed.
The eXVG gas fuel metering valve is designed for use with industrial engines up to 13,000 HP and turbines up to 10 MW.
The engine control system detected this and opened the fuel metering valve fully, but with no real change in the fuel flow to the engines," said the AAIB.
