What You Should Know About Control Valves

Posted on: 8 October 2018


Valves can be used to control the flow of water into your property. They are also important for maintaining water pressure. Valve repair is an important task carried out by contractors to ensure that the valve still works effectively.

Water control valves

Control valves are used to control the flow, level and pressure of water in your pipes. If your property has a high level of water pressure, a pressure reducing valve may be used. Control valves can also handle sudden extremities in pressure by closing and opening automatically to control the flow of water.

Level control valves may be used in reservoirs, tanks and towers to avoid overflow. This is because a float valve will maintain a maximum water level in the tank, tower or reservoir and an altitude valve will monitor water levels from the ground.

Flow control valves can deal with a greater demand on the supply of water. They can also be used to set a limitation on the extent of the water flow. Additionally, they can also stop water from being lost due to a break in the pipe.

Fire control valves

Control valves can be designed to override the limit of water flow when there is a fire. There are a number of valves available to deal with fires, this includes, pressure relief valves, pressure reducing valves, deluge valves and altitude valves.

Pressure relief valves can activate when the pressure becomes high. They relieve the pressure and prevent damage. Pressure relief valves can also be used to assist with pumping water and fire foam. In a fire pump or fire foam system, a pressure relief valve will stop the pressure from becoming too high for the mechanism.

A fire flow bypass valve is kept closed during normal water usage and it automatically opens when there is a decrease in pressure. It allows water to flow at a high pressure during a fire.

A fire system pressure control valve reduces the pressure in the pipe to a more manageable pressure for your water system. It will maintain this despite changes in pressure or demand.

What does valve repair include?

A contractor will examine your pipes and report any issues with the valve. They may use diagnostics and investigative testing to discover the cause of the problem. They may also test the pressure and functionality of the valve. They may replace the valve or they may modify the valve. Modifying the valve may include welding or coating. After repair, you should receive a certificate from the contractor.
