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.
