REDUCE OPERATIONAL COSTS
Flow Stability Means Improved Uptime
Extreme water depths mean extreme conditions, like frigid
temperatures, high pressures, and corrosion. Such severe
temperatures, pressures, and pressure drops can result in the
formation of ice-like structures, called hydrates. Hydrates
can cause large plugs that block piping and other equipment,
causing them to become inoperable. High pressure and low flow
rates can also cause erosion, often requiring increased valve
maintenance or costly downtime.
Mono-ethylene glycol (MEG) is used as a freeze-protectant to
help inhibit the formation of hydrates. MEG injection control
valves regulate the flow of MEG and are critical to providing
precise and continuous MEG dosage, as even the smallest
percentage loss of MEG dosage can lead to hydrate formation.
Tested to the highest requirements, including seat leakage,
packing emission, cavitation, and erosion, Fisher control valves
and instruments used in MEG injection applications are designed
to prevent erosion damage to the seat and plug to maintain
integrity for tight shutoff and precise, continuous flow control.
The valve plug and seat ring are uniquely matched to regulate
flow during very low flow and high pressures. A valve with
built-in reliability means preventing hydrates from the start,
so you can meet the flow requirement and attain the highest
performance from your process.
