Dual pump protection valves

Dual Valves Australasia presents pump protection valves designed for various applications in mining, power generation, sand, chemical, paper and environmental segments.

Dual pump protection valves (DPPV) have been designed and manufactured to provide protection against excessive fluid temperature rise within the pump housing. Low flow conditions can cause flashing, cavitations, vibration, bearing failure and damage to mechanical seals and pump housing.

Dual pump protection valves are fitted to the suction side of the pump. Key benefits of the DPPV valves include cost-effectiveness, simple installation and lightweight construction for easier handling.
