SURGE SENTINEL ELECTRONIC SURGE ANTICIPATOR VALVES FOR WATER
Producto N° 9987
SURGE SENTINEL Electronic Surge Anticipator Valves for Water
Uses Golden-AndersonÒ differential piston main valve.
Much simpler controls than any other surge anticipator for added reliability.
Super-sensitive pressure 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.
Globe or angle body with ANSI, BS, DIN or ISO flanges.
Manufactured in sizes 2½ to 24 inches (65 to 600 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.
