GEM-FLOW, G500-PS, Pressure Sustaining Valve 1½”- 4″
GEM-FLOW, G500-PS, Pressure Sustaining Valve 1½"- 4"
G500-PS model pressure sustaining hydraulic control valve maintains valve upstream pressure value constant. Valve is opened when line pressure reaches the preset pressure level. It ensures that pump motor within pumping systems will start without load. It also prevents positive pressure waves caused by pump during start-up. The valve controls upstream pressure value continuously and keeps it at a constant value without being affected from changes in flow rate. When no flow exists, it closes tightly by itself.
• Use G500-PS for maintaining a constant upstream pressure or to avoid unwanted high pressure
