Structural Features:

Precision metering port achieving accurate flow-opening relationship
Standard pipe connection interfaces
Actuator mounting face precision machined for assembly accuracy
Optimized internal flow passages with low flow resistance
Anti-vibration structure validated for dynamic environments

Working Principle: External actuator drives the spool to change the opening according to control system commands, thereby precisely regulating the gas flow cross-sectional area. The precise geometric relationship between port area and actuator position ensures gas flow varies proportionally with the command signal. The valve can form a closed-loop control with an external flow measuring device, or be directly managed by a digital valve position controller.

Installation Requirements:

Confirm valve body flow direction marking is consistent with system piping before installation
Configure gas filters of specified accuracy upstream and downstream of valve body to prevent impurities from damaging metering surfaces
Select installation location facilitating actuator and control cable layout
Provide reliable support for valve body to avoid direct action of piping stress on valve body
Adopt standard sealing method for gas pipe connection to ensure leak-free

Usage Precautions:

Gas cleanliness is key to reliable valve operation; inspect and replace filters regularly
Strictly follow gas system safety operating procedures during installation and maintenance to prevent danger caused by leakage
Avoid long-term operation under over-pressure or out-of-temperature-range abnormal conditions
Regularly inspect external valve sealing and connection fastener condition
Perform leak test and functional verification before re-commissioning after long-term shutdown
