Pressure Sustaining Valve Double Chamber IR-130-DC-3W-XZ

The BERMAD Model IR-130-DC-3W-XZ Pressure Sustaining Valve is a double chambered, hydraulically operated, diaphragm actuated control valve that sustains minimum preset upstream (back) pressure and opens fully when line pressure is in excess of setting. The valve comprises two major components: The body and the actuator assembly. The actuator assembly consists of both an upper and a lower control chamber. The double chambered valve operation is independent of valve differential pressure. This develops maximum power, ensuring immediate valve response combined with inherent soft closing.
