Chemical Injection Metering Valve (CIMV) , also called as Chemical Throttle Valve (CTV) or Subsea Chemical Injection Delivery System (SCIDS) , is a device for the precise control and metering of various chemicals (such as methanol, MEG, scale inhibitors, etc.) injected into subsea production system. Precise control of the chemicals flow to subsea production system is crucial for preventing the formation of hydrates, wax, and scales in pipelines, which is vital for ensuring the normal function and long-term stable operation of subsea production system. Two versions of CIMV, high flow rate and low flow rate respectively, were developed utilizing redundant metering technologies that combines fixed and adjustable throttling, which is 100% intellectual property. The CIMVs have been qualified by the authoritative third-party DNV which guarantees 30 years service life and accurate metering precision under harsh conditions such as low temperatures at the seabed, high internal and external pressure, periodic dark current vibrations and shocks etc.
