SURGE SENTINEL Electronic Surge Anticipator Valves for Sewage

SURGE SENTINEL Electronic Surge Anticipator Valves for Sewage Specially designed for use with raw sewage and other debris-laden fluids. Relief pilot opens valve on over-pressure not preceded by significant sub-normal pressure. "Surge Sentinel" electronic control box senses sub-normal pressure, triggers 24VDC solenoid to open valve with trickle-charged and monitored heavy-duty battery, keeps valve fully open for duration of digital timer then slowly closes valve after surge has dissipated. Long radius 900 elbow or in-line wye body with ANSI, BS, DIN or ISO flanges. Manufactured in sizes 2 to 16 inches (50 to 400 mm). Function and Applications Protects system from excessive over pressure by opening quickly when inlet pressure exceeds pre-set maximum and slowly closing tight when pressure returns to normal. Also opens quickly on pre-set under pressure, remains fully open for a pre-determined time and then slowly closes tight when pressure returns to normal. Used in pump stations where sudden pump trip can produce significant "down-surge" allowing valve to open in anticipation of returning "up-surge" (over-pressure) for a greater degree of protection.
