Natural gas, coal gas, liquefied petroleum gas and other non-corrosive gases.
♦Valve body straight-through (axial flow) large flow, low noise, flow rate <50m/s, noise <80dB
♦The top-mounted structure can be repaired online, and the valve body can be replaced without removing the valve body
♦Self-operated overpressure shut-off and self-operated under-voltage shut-off are standard configurations
♦Easy to install in any position
♦High shut-off precision
♦Pressure can be controlled at one or more points in the system
