Top 4 Problems When Using Regulating Valves

Excessive water pressure, defined as anything more significant than 80 psi, can cause difficulties in a home’s plumbing system. Such stress can eventually cause damage to water-using equipment, as well as leaks and the phenomenon known as water hammers. Fortunately, by putting a pressure regulator valve on your main water line, you can keep your water pressure within a safe range. A valve trader can help you understand the problem well.

As the name indicates, a pressure regulator valve limits water pressure to a safe level specified by your plumber. This plumbing component, while helpful, may create issues with time. Continue reading if your home has a regulator valve. This article delves further into three frequent problems with water pressure regulator valves.

A plumber can usually fix this problem by dismantling and cleaning your regulator valve. Unwanted mineral deposits are loosened and dissolved by soaking the valve in a calcium and lime remover. After cleaning the components, the plumber reassembles the valve, which should now work without any limits. 

Blockages (valves)

A water pressure regulator valve is similar to an outside hose faucet in that it regulates the flow of water. The water flow via the valve may be increased or decreased using a screw at the top. Tightening the screw inhibits water flow and raises the maximum water pressure limit. 

However, regulator valves from valve suppliers can acquire clogs over time, restricting flow beyond the recommended quantity. High mineral content in your municipal water supply is a common cause of such obstructions. Mineral deposits build up inside the valve body, resulting in less-than-ideal household water pressure. 

Internal Components That Have Been Damaged 

Direct-acting and pilot-driven pressure regulator valves are the two primary types. Direct-acting valves from valves trader in UAE are used in most home water systems. A heat-resistant diaphragm is linked to spring in these valves. When enough water is pushed across the diaphragm, the pressure forces the valve to close more firmly. 

On the other hand, low water pressure causes the diaphragm to relax, keeping the valve open wider. The moving elements of this system are subjected to a large amount of forced overtime. Those components may eventually deteriorate, rendering them less responsive than they should be. 

A plumber may theoretically disassemble a regulator valve and repair any damaged components. However, this approach frequently takes longer — and costs more — than just replacing the valve. Replacing your valve will help keep issues at bay for as long as feasible. 

Incorrectly set pressure

An exposed screw stands at the top of a water regulator valve. A plumber can use this screw to adjust the tension on the spring inside the valve body. The maximum pressure is increased by tightening the screw, making it more difficult for water pressure to move the diaphragm. The impact of loosening the screw is the polar opposite. 

Don’t assume that your regulator valve has failed because there isn’t enough pressure. It’s wise that all you require is a valve adjustment. A pre-set pressure restriction of 50 psi is found on almost all pressure regulator valves. Most homeowners believe this is insufficient pressure. 

Mechanical friction  

It can occur between moving portions of control valves, particularly between the valve stem and the stem packing. Valve packing and Components must move past each other over the whole range of valve stem movement in valve packing and some trim forms. Some friction is unavoidable, but the goal is to keep conflict bare minimum while maintaining a pressure-tight seal. 

When there is friction in a control valve, the force required by the actuator to move the valve rises. The only major issue with higher pressure, whether the actuator is electric or hydraulic, is the additional energy required by the actuator to move the valve (recall that mechanical labor is energy-intensive). 

The average velocity increases as it flows through the constrictive channels of a control valve. The kinetic energy of fluid molecules increases as fluid velocity increases via the constrictive passageways of a control valve. The potential energy in the fluid pressure must decrease following the Law of Energy Conservation. As a result, fluid pressure drops within the constriction of a control valve’s trim as it throttles the flow, then rises after it exits the trim’s constrictive passages and enters the valve body’s larger sections.

Conclusion for valves

Erosion, when the passage of solid particles wears the valve trim and body, is a typical problem with control valves used in slurry service (where the process fluid is a liquid containing many complex, solid particles). Wet steam, which comprises droplets of liquid water carried at high velocity by the steam flow, is another source of erosion in control valves.
