Working Principle: The actuator receives electrical signals from the control system and produces mechanical displacement, driving the spool to change port opening, thereby precisely controlling gas flow. The control system adjusts valve position in real time based on turbine speed, load demand, exhaust temperature and other parameters, ensuring the turbine receives appropriate fuel. The valve design ensures a deterministic and highly repeatable correspondence between flow and opening.
Installation Requirements:
-
Flow direction and installation orientation comply with valve body markings and design specifications
-
Configure gas filtration devices of required specification upstream and downstream of valve body
-
Select location facilitating actuator installation and electrical wiring
-
Piping system shall have independent support to avoid stress transmission to valve
-
Complete purge, leak detection and full-stroke test before system commissioning
Usage Precautions:
-
Maintain gas cleanliness; perform regular filter system maintenance
-
Follow gas system safety operating and explosion-proof regulations
-
Regularly inspect external valve sealing and connection fastener condition
-
Prohibit long-term operation under over-pressure, over-temperature or severe pulsation conditions
-
Seal inlet and outlet when in long-term storage; keep in dry environment
