High Flow CIMVsH120-S thru H128-S, H120-R thru H128-R

SkoFlo H120 are the industry leading high flow chemical injection metering valves. CIMVs used to inject high dose rate chemicals, typically MEG (Monoethylene Glycol), Methanol and low dose hydrate inhibitors to prevent hydrate formation. The H series CIMV brings together the following advantages:

SkoFlo CIMV technology delivers precise and stable flow, regardless of fluctuations in supply or well pressure.

Pressure Independence: Flow delivery rates are unaffected by fluctuations in supply or well pressure.

Pressure-Balanced Piston: SkoFlo’s proprietary constant flow mechanism uses no electric power.

Maximum Debris and Filming Tolerance: The ceramic coated surface eliminates filming and prevents clogging caused by debris build-up.

Overall System Stability: Rapid response time eliminates surging, which leads to greater system stability.

Pressure-Balanced PistonThe Pressure-Balanced Piston provides pressure independence, maximum debris tolerance, which in turn, delivers precise chemical injection.

The SkoFlo CIMV is able to maintain precise chemical injection flow rates regardless of upstream platform to the valve and downstream valve to the well pressure fluctuations. Upstream and downstream pressure fluctuations create a net force on the piston, which is countered by a spring force to maintain constant flow. Response time is within milliseconds with no “hunting” or control iterations as opposed to a motor operated stem that needs to open and close, also known as dithering.

Interfaces, I/O, and CommunicationsThe Subsea Control Module (SCM) provides electrical power via a 4-way electrical connector (either Siemens Tronic or Teledyne ODI). Fluid lines are connected to the CIMV via Hunting Hydraulic Couplers. The system architecture uses communication protocols available in CANbus SIIS 2 and Modbus configurations.

Interfaces are configured to industry standards.

Available for use with ROV Mate and Stab Mate electrical connections.

Pressure SensorsSkoFlo incorporates four pressure sensors for maximum functionality. Two sensors are utilized to measure Differential Pressure (dP) across the orifice which provides continuous flow measurement. Two additional sensors add diagnostic functionality by measuring inlet and outlet pressure.

Innovative Pressure-Balanced Piston design that allows chemicals to be distributed at different injection points from a common line. This reduces the number of umbilicals which significantly reduces the cost to the operator. The pressure-balanced piston also provides a means of control that is more tolerant to debris and fluid filming than a throttling stem directly driven by a gear motor.

Large particle debris produces a net force on the piston which is countered by a spring force; pressure created on the piston surfaces by debris is pushed out through the outlet instantaneously.

Fail as-is without drift: During loss of power the pressure-balanced piston will not only continue injecting but it will maintain flow at the set flow rate. This is regardless of debris or system pressure fluctuations.

Unmatched Stability: The nearly instantaneous response results in a stable system when higher flows create large pressure fluctuations in parallel systems.

Flow Measurement Techniques

Flow by dP (Differential Pressure) utilizes an internal orifice and a dP sensor system that forms an orifice-type flow meter. The LF valve utilizes a variable orifice while the HF valve does not. This method is preferred for continuous flow measurement because the CIMV's internal orifice meter yields higher accuracy compared to Flow by Stem.

Flow by Stem is calculated using the position of the stem. During the calibration of the valve, the external flow rate and stem position are recorded in a calibration table. This table is used to estimate the flow rate based on a known stem position. The Flow by Stem method is the least accurate of the CIMV flow measurement methods. As a general rule, stem position should only be used as a diagnostic check to confirm Flow by dP.

The High Flow CIMV architecture provides two ways to measure flow including Flow by dP and Flow by Stem.

Flow by dPCalculated by utilizing an internal orifice and a dP sensor system that forms an orifice-type flow meter. This is a continuous flow measurement.

Flow by StemCalculated by measuring the motor stem position. The external flow rate and stem position are captured in the CIMV calibration table.
