Application of Pressure Relief Valve:
To protect the system against high pressure surges when pumps are shut down, this fast opening – slow closing relief valve dissipates the excess pressure.
Application of Pressure Sustaining Valve:
When installed in a line between an upper zone and a lower area of heavy demand, the valve acts to maintain desired upstream pressure to prevent "robbing" of the upper zone.
