  1. Introduction

It is a new authorized water power control valve of our company, awarded the national patent.

It’s mainly available for service pipe on diesel pump and electric pump , to ensure pump sets to supply water at a rated head and flow, specially for preventing overloading at a low head and overloaded starting. It can be used for water supply and fire pump system in pipeline for auto-inspection and decompression running.

This constand head/check 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

2. Application of this constant head check valve

It solves problems on application of pumps in the field of water industry.

2.1 Pump can be started at low axis power to decrease the drive start power

2.2 Pump can be worked under a huge of pressure diversification , enable working in a high efficiency for saving energy.

2.3 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

2.4 Pump is injecting water to pipeline as the model section situation to ensure the suited drive equipment non-overloaded

2.5 Pump is injecting water to pipeline as the model section situation to ensure the suited drive equipment non-overloaded

2.6 When pump is stopped, ensuring pump and pipeline connection is cutoff to prevent water flowing back
