SkoFlo Subsea Chemical Injection Metering Valves (CIMV) feature SkoFlo’s industry leading pressure independent technology. Subsea CIMVs are operationally rated up to 15,000 psi, ROV installable, and remotely adjustable, and draw minimal power. During flow adjustment SkoFlo valves draw 4 watts and only draw 1-2 watts while idling. (Stated power values are per valve core.) Communication interface to the SCM can be Modbus or Canbus SIIS level 2.
SkoFlo has over 800 subsea valves in service and is currently the only supplier of subsea chemical injection valves that has been certified by the SIIS organization to be compliant to the SIIS Level 2 communication protocol.
SkoFlo Subsea Back Pressure Regulators (BPRs) are anti‐siphoning, self‐regulating devices that create back pressure in chemical injection lines to prevent uncontrolled delivery of chemicals into production wells. BPRs prevent chemicals from draining into injection points when a chemical hydrostatic head exceeds injection pressure and production wells become sub‐ambient.
Subsea BPRs regulate inlet pressure when the well pressure falls below the factory set point of the device. It achieves this regulation with a simple debris tolerant mechanical device that does not need power or communication to the SCM. BPRs are self-regulating devices activated only when required or needed.
Upstream and downstream pressure fluctuations create a net force on the patented pressure balanced piston, which is countered by a spring force to maintain constant flow.
Accurate Flow Delivery
Pressure‐balanced piston provides instantaneous means of control at different injection points from a common line that is more tolerant to debris and fluid filming. No pneumatic or electric power sources required for control.
Accumulated debris results in a net force on the piston that instantaneously lifts the pin slightly from the seat, passing the debris through the outlet. This net force is countered by the spring force that returns the piston to its balanced flow rate position.
