Water supply and drainage comprehensive: self-reliance type differential pressure of the pneumatic valve performance, characteristics, function analysis

self-reliance type differential pressure pneumatic disc structure for the pneumatic valve, pneumatic valve stem unbalanced force is small, compact structure, and used for heating, Air conditioning) Water series, constant differential pressure of the control system, and has the following characteristics:
and constant differential pressure control system.
, support for internal independently regulate the controlled system.
differential pressure fluctuation, absorb the network.
and adopts advanced stepless regulating structure, control pressure general adjustable ratio can reach:.
and eliminate congestion function automatically.
and flange dimensions conform to GB. In the gray cast iron flange dimensions.
ZYF - Self-reliance type pneumatic valve, pressure differential control does not need external energy, relying on the modulated medium pressure changes automatically adjust itself, automatic eliminate the residual pressure head and pipe network pressure fluctuation caused by the flow of change, constant user import and export pressure difference, help stabilize the system.
self-reliance type differential pressure control pneumatic valve is especially suitable for household metering and automatic control system.
