1.Model : MSC-PA 2.Reference standards API RP 14A, API RP 14B, API RP 14C , NACEMR-01-75, EN 50018. 1.          Control objectsThe multi-well control panel is applicable of the centralized control of the wellhead safety valves of the multiple oil and gas wells and controls the SCSSV, master valve, wing valve and choke valve of every well.2.          Reference standards API RP 14A ,  API RP 14B ,   API RP 14C ,  NACEMR-01-75 ,  EN 50018.      3.          Basic parameters

Type	Pneumatic control system
Service	Standard or H2S-CO2(NACE)
Quantity of well	2~5 ,  5~10 ,  more than 10
Common Hydraulic Module	Air driven pumpHydraulic outputs 5,000-to 10,000-PSIGESD loop &Pilot supply, 50 ~100PSIG
Single Well Module	Control SCSSV, Master Valve, Wing ValveRemote ESD, Fusible plugs, Low pressure/high pressure, Manual at panel

 4.          Principle and functionsOperation principle: The panel uses the module design and is made of common module, single well module and RTU module. Pneumatic pump is used to supply the hydraulic pump (manual pump as backup) and the pneumatic pressure is used as the pilot control loop.

Main functions: RTU shutdown ,  Fusible plugs ,  Low pressure/high pressure ,  Manual at panel
