The valve eliminates surges caused by the start-up and shut-off of vertical or submersible pumps. It is a relief valve, assembled on a T-junction of the main pipeline. When the pump starts, the valve slowly closes, gradually increasing network pressure. Before pump shut-off, the valve slowly opens, gradually reducing network pressure.

• No slam operation
• Simple and reliable design
• Easy installation and maintenance
• Low Resistance and high flow capacity

Optional Deep Well / Pump Control Valve applications:

• DW/PS Deep-Well pump control & pressure sustaining
• DW/FR Deep-Well pump control & flow-regulating

Mounted on a tee junction, on the discharge head of deep well, upstream of the Check valve. Eliminating pressure surges caused by sudden change of the pipe velocity through start-up and shut-off.

Optional Deep Well Control Valve applications:

• DW/PS Deep-Well pump control & pressure sustaining
• DW/FR Deep-Well pump control & flow-regulating
