What is a cycle stop valve and what is it used for?

The most effective way to have a constant water pressure is with the cycle stop valve thanks to the safety switch type closing system it has, which closes the valve when the pressure is too high or when the pipe becomes stagnant.

This article will explain in detail how this pump system works, what advantages it offers, where it should be installed and much more.

So, stay with the experts in industrial pumps and valves, IndusCo, and learn all about cycle stop valves.

What is a cycle stop valve?

The well pump cycle stop valve is a simple device that drastically reduces the number of times a water pump is turned on and off.

This means that it reduces the strain on pumping equipment, the problems or damage it may acquire while operating and maintenance costs.

Cycle stop valves are used with small pressure tanks and still have the ability to double or triple the life of pumps and motors.

What is a cycle stop valve for?

It is important to know what a valve that automatically adjust is used for, so you will know in which situations to use it. They are used for:

  • Replace large water towers and pressure tanks.
  • Eliminate water hammer and transient pressure waves.
  • Provide variable speed flow and good control of system pressure.
  • Provide a minimum flow rate that is required to cool the pump and replenish the pressure tank when required.

The truth about cycle stop valves is that they increase the back pressure on the pumps when necessary and never allow the head to close completely, i.e., it never closes completely.

Where to install a cycle stop valve?

The stop cycle valve is installed in flammable liquid lines, such as oils or fuels, and also at the tank outlet.

They are generally used in major machinery or human workstations.

In addition, it is installed in the cold water supply piping leading to the heating equipment.

The valve is used to shut off the water supply when servicing or repairing the heating equipment.

Types of Cycle Stop Valves

These valves are manufactured to meet various specifications, but also come with different mechanisms and designs to suit the fluid flowing. The types that exist are:

Ball Cycle Stop Valves

They are designed with lever handles that operate with a short 1/4 turn of the handle.

The open valve is aligned with the direction of the water pipe and flows through it. When the handle closes, the ball rotates, cutting off the water supply.

However, the ball valve should not be confused with the pump control valves, as these are also used to handle water.

And the control valve that automatically regulates pressure and flow rates, needs more maintenance than the ball valve.

Butterfly cycle shutoff valves

The function of the butterfly valve is similar to all types of valves, and is to determine the passage of hydraulic fluid through a channel belonging to a specific system.

The only difference is that this valve uses a pressure switch control and ensures long term operation.

Gate cycle shutoff valves

It is so named because it has a metal gate inside the valve that is used to turn it on and off.

A circular handle is in charge of lowering and lifting the door, when lowering the water flow stops.

Its mechanism is very similar to the ball valve, allowing full flow or shut-off of water.

Globe Cycle Stop Valves

It also has similarity to the ball valve because of its rounded body, but with the difference that the globe valve adjusts for reduced cycling of water. They are often seen in applications that require a variable flow pattern.

Plug Cycle Stop Valves

It has a cone or cylinder shape that is rotated inside the valve body in order to control the amount of water passing through it.

Its passageways are hollow and are installed horizontally to allow easy flow through the valve when it is open.

How does a cycle stop valve work?

The cycle stop valve well pump functions to regulate the flow of gases and liquids in pipelines by opening and closing.

Parts that are permanently exposed to the influence of chemicals, as well as high or low temperatures, are not damaged by corrosion or temperature.

Liquids can create continuous vibrations in the cycle stop valve, but the cycle stop valve is not affected.

Installation of cycle shut-off valves

In case you don’t know how to do a cycle stop valve installation, don’t worry, we will explain how to do it:

  • Make sure the well is clean, as debris in the pipes can damage the 2 cycle stop valve.
  • It should be installed downstream of the pump and on the side of the pressure tank.
  • The cycle stop valve model CSV125 must be hand tightened with Teflon tape on the threaded ends.
  • The pressure tank must be installed with a tank cross or a ”T”.
  • The pressure switch and other types of controls should be installed close to the tank.
  • The closing pressure of the switch must be higher than the pressure of the valve.

Advantages of this type of valves

The cycle stop valve has pros and cons, which are important to know. The advantages they have are:

  • It is easy to use and operate.
  • Economical product with high quality.
  • Easy to repair and simple maintenance.
  • It does not require lubrication and is an efficient product.

However, cycle stop valve problems can also occur, such as:

  • The pressure tank is far away.
  • The valve switch is not set correctly.
  • Various check valves working against the system.

Industrial applications of cycle stop valves

The industrial applications that the valve has are:

  • Cryogenic use.
  • Natural Gas Vehicles.
  • Cycle stop valve for well pump.
  • Fuel, diesel, biodiesel.
