Product description:
Pressure regulator without additional energy, the use of the media itself is the media as the power source. Automatically control the valve medium flow, so that the pressure after the valve to maintain a constant pressure stabilizer. Has
been widely used in continuous gas acquisition and transportation of
natural gas, urban gas and metallurgical, petroleum, chemical and other
industrial production sector.
Valve Features: Control of high precision, general than ZZY type direct operation of the regulator about double high. Adjust
the pressure ratio (such as the valve before 0.8MPa, valve 0.001MPa) is
particularly suitable for micro-pressure gas control.
Pressure set in the pilot to achieve, so convenient, fast, labor-saving time-saving can be run continuously set.
