Model 47-09 differential pressure sustaining valve is a fully automatic and liquid-pressure control valve. Using the pressure difference between two pipes controls the pressure difference not to over the acceptable range of the system during valve operation or flow rate variety. The valve will automatically open when pressure difference is increased, and will automatically close when pressure difference is decreased. So that it can maintain the pressure difference between two pipes.

Notice:
※When installing the valve, strongly request to leave enough space for maintenance. It is necessary to install the filter at the front section of the valve to avoid foreign materials to block the valve and affect the operation of the valve.
※King-Tech reserves the right to make any revisions on the valve model and size without prior notification.
※When making any design drawing, installation drawing or construction drawing, please do get our approved CAD with our signature, or we will not be responsible for any mistake.
