Product Details


ZZC self-contained differential valve is a regulating system that needs no external energy but can self-regulate pressure difference of one or two media to keep the pressure difference constant. For example, in gas combustion system of industrial furnace, it is used to control the flow of two fuel mixture ratios of A and B to reach the ideal combustion conditions, thereby saving fuel and investment. It can also be used in regulation systems of pressure reduction,micropressure and differential pressure for various industrial gases such as coal gas, natural gas, LPG, ammonia gas, nitrogen, oxygen, or used in  seal oil system of hydrogen cooled-generator set to control the pressure difference between seal oil and hydrogen gas, thereby guaranteeing reliable sealing.
