Production Description:

Constant life /special check valve is a new authorized water power control valve of our company. it' s mainly available for service pipe on diesel pump and electric pump , ensure pump sets to supply water at a rated lift and flow, specially for preventing overloading at a low lift and overloaded starting. It can be used for water supply and fire pump system in pipeline for auto-inspection and decompression running. This valve is widely to use for water supply system such as daily, industrial and smelting and fire protection, and a multi parallel connection pump sets system etc. it' s a ideal valve for keeping pipeline safety and running high efficiency. The main characteristic is that enable valve to self-regulation as the diversification of pipeline pressure for keeping the pump life and flux constantly , keeping the pump at a model section working , and ensuring drive requirement is unable to overload in high efficiency. The main six functions as following: 1. Pump can be started at low axis power to decrease the drive start power. 2.Pump can be worked under a huge of pressure diversification , enable working in a high efficiency for saving energy. 3.Pump can be worked under a huge of pressure diversification , enable working as the model section situation for ensuring the suited drive equipment non-overloaded. 4.Pump is injecting water to pipeline as the model section situation to ensure the suited drive equipment non-overloaded 5.Pump is injecting water to pipeline as the model section situation to ensure the suited drive equipment non-overloaded . 6.When pump is stopped, ensuring pump and pipeline connection is cutoff to prevent water flowing back
