The function of a Cycle Stop Valve (CSV) is to:
- Provide variable flow and constant pressure control superior to VFD systems
- Replace large pressure tanks and water towers
- Provide minimum flow required to cool the pump and/or motor
- Provide minimum flow to replenish the pressure tank when needed
- Eliminate transient pressure waves and water hammer, stop line breaks

What does a hydraulic pressure control valve do?
These valves can do the pressure control of a system an example for this is, using a line relief valve to limit the maximum allowable system pressure. These valves can be seen in hydraulic systems and they can protect the hydraulic system. In order to achieve the pressure control, pressure relief, and pressure regulation must be done.

What is a CSV in plumbing?
These devices are known by several names. Constant Pressure Valve (or CPV), Cycle Stop Valve (or CSV), are the names most commonly used to describe a valve that mechanically controls the output flow from a pump to match the usage. These valves have no electronics.
What does a constant pressure valve do?
Constant pressure valves control the system pressure on the downstream side of the valve, i.e. to the tank, the pressure switch and all points of usage in the house.
How does a CSV1A work?
CSV1A / CSV2W1. As your demands vary, the CSV reacts to changes in pressure and opens and closes accordingly. This enables it to hold a constant pressure as long as your demand is more than the minimum control flow of 1 or 5 gpm depending on the model your choose (1A-1gpm, 2W-1 or 5gpm) .
Where does CSV valve install?
The CSV (Cycle Stop Valve) should be installed downstream of the pump on the pump side of the pressure tank / pressure switch. Everything pumped needs to go through the CSV before it goes anywhere else. Any and all water outlets have to be downstream of the CSV valve.
Can you use a pressure switch without a pressure tank?
We recommend having a pressure tank particularly when you have a shower or a toilet where the pump is rarely operating at 100%. Without a pressure tank or accumulator tank the strain will be on your pressure switch/controller, which may cause it to fail early at an inconvenient moment.
Does a constant pressure well pump need a pressure tank?
1:195:39Constant Pressure System VS Standard Pressure System - YouTubeYouTubeStart of suggested clipEnd of suggested clipThe pump would start when the pressure gets down to about 40 psi and cutoff when it gets to 60 psi.MoreThe pump would start when the pressure gets down to about 40 psi and cutoff when it gets to 60 psi. We can adjust that up and down a little bit but you need to keep that 20 psi.
Are constant pressure well pumps worth it?

How do I keep my house water pressure constant?
4 Ways to Increase Home Water Pressure When You Have a WellAdjust Your Pressure Tank Settings. ... Consider a Pump with a Higher Flow Capacity. ... Upgrade to a Constant Pressure System. ... Install a Water Pressure Booster Pump.
How do you adjust a cycle stop valve?
The CSV1A is adjusted by turning the adjustment stem clockwise to increase downstream pressure and counter clockwise to decrease downstream pressure. Adjust the CSV1A until the pressure steadies at your desired working pressure. Tighten the lock nut. The valve is set.
How do I stop my bike pump?
What You Can do to Prevent Excessive Cycling on Your Water PumpRepair the tank air volume control.Drain the water tank and let air re-enter the tank.Drain the water from the tank and use the air inlet valve to recharge air back into your tank. The air charge should be 2 psi lower than you pump cut-on pressure.
Cycle Stop Valves
This diagram shows the difference between a system with a Cycle Stop Valve (top) and a system without a Cycle Stop Valve (bottom.) The Cycle Stop Valve delivers constant pressure while eliminating water hammer and reducing stress to pump.
