Description：China ZZVP Self-Operated Pressure Regulator manufacturer, factory and supplier.

ZZVP Self-Operated Pressure Regulator manufacturer, factory and supplier in China. ZZVP Self-Operated Pressure Regulator is an energy-saving pressure regulating valve that does not require external energy and only relies on the pressure change of the medium to be adjusted to achieve automatic adjustment and stable pressure difference. ZZVP Self-Operated Pressure Regulator can be applied to industrial furnace systems to control the flow ratio of two materials, such as gas and air, to achieve ideal combustion. ZZVP Self-Operated Pressure Regulatoris used in the hydrogen-cooled generator set sealing oil system to control the pressure difference between seal oil and hydrogen to ensure reliability. seal. When the low pressure end of the differential pressure valve is open to the atmosphere, it is a micro pressure valve.
