All boilers are equipped with steam pressure gauges, low water cutoffs, safety valves, FW stop and check valves, blow down valves, continuous blow down metering valve
, chemical feed valve, FW regulator with pre-piped three valve bypass, BMS/ combustion controls, complete fuel train and pilot ignition system, forced draft fan, motor and starter, steam non-return valve, stack, water column and site glass.
In such an environment, the corrosion-resistant life of a plated carbon steel metering valve
or system component will only be weeks to months.
(Pressure switch high, Less Install flow Temperature 5 5 5 125 metering valve

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.
