CSV Beats Ordinary Pump Control Valves Ordinary pump control valves close drip tight, completely dead heading a pump. Adding bypass tubes or drilling holes, leaves the probability that debris or a buildup of mineral and organic material, will block the bypass causing a deadhead condition, destroying the pump and any water cooled motor. Also, with a hole or bypass tube the main valve still closes completely which can cause "hunting", water hammer, and pressure surges. Hundreds of brands of ordinary pump control valves are available. These include Cla-Val®, Watts®, Bermad®, Flomatic®, Singer®, OCV®, Zurn Wilkins®, Ross®, Golden Anderson®, Dorot®, Netafim®, and others. All of these valves are fully closing which can give a multitude of control problems. Cycle Stop Valves allow 5 GPM through a non closing valve seat. No bypass tube or port is present until the valve closes. Blockage is not possible as every time the valve opens the 5 GPM bypass is split into two half moons. Eliminating any possibility of deadheading saves the pump, seal, and any water cooled motors from overheating. A non closing seat also allows us to increase valve reaction speed tremendously without causing water hammer or pressure surges. Reaction speed of control valves must be able to keep up with flow changes in the field or pressure surges and swings will be accentuated. |
