Pressure reducers - Import export

The valve reduces high upstream pressure to a pre-set lower and constant downstream pressure level, regardless of fluctuating flow or varying upstream pressure. A hydraulic regulating pilot drives the valve. The pilot is able to detect upstream pressure values and regulates closing steps of the valve until the pre-set pressure value is restored.

The valve isolates pumps from the system during pumps starting and stopping to protect pipe lines and pumps itself. The valve is equipped with a control solenoid valve that is switched on at pump starting and is able to fulfill pipe line gradually, reducing pressure rising peaks and allowing soft starting of the pump with closed outlet. The valve controls pump stopping as well, gradually closing before sending a closing signal to the pump. In case of casual pump stop, the valve acts also as an automatic check valve, preventing backflow over the impeller.

Serie LPE HELICAL FANS FOR WALL The LPE serie’s fans, present constructive characteristics that allow both the utilization in the industrial applications and the installations in the tertiary environments (workshops, stores, breedings, glasshouses) where there is the real necessity of the employment of a fan with easy installation, low consumptions, and reduced noise pressure levels.
