  • Maintaining a pressure reducing valve: 5 things to check

    Like your car, your body and nearly every appliance you own, control valves require regular maintenance to continue working efficiently. However, due to budget and time constraints, we don’t always give our valves the TLC they need to perform at their best. Unfortunately, ignoring pressure reducing valves can mean serious ...

  • Top 8 things to check when maintaining a Pressure Reducing Valve

    Like every other piece of mechanical equipment we use, a control valve does require some maintenance. As budgets are stretched and time is tight, it can be tempting to ignore checking on valves that are often located in underground vaults and give years of operation without complaint, but eventually like everything else, they will fail. This article looks at 8 simple steps that if undertaken ...

  • How to boost the performance of Pressure Reducing Valves without breaking the budget.

    Pressure Management has become a very useful tool around the world for controlling leakage in piping networks. This has primarily been achieved by utilities forming DMA’s (District metered Areas) and pressure zones in their systems. Typically, pressure is managed by utilizing a pressure reducing valve that can either have a single fixed pressure reducing pilot set point or pressure flow ...

  • Hydraulic characterization and transient response of pressure reducing valves: laboratory experiments

    A pressure reducing valve (PRV) regulates the outlet pressure regardless of the fluctuating flow and varying inlet pressure, thereby reducing leakage and mitigating the stress on the downstream water distribution network (WDN). Notwithstanding the crucial importance of PRVs, few experimental data are available in the literature. The aim of this paper is to overcome this gap by means of the ...

  • Advantages of Using Flow Meters to Reduce Pressure Drop

    Plant operators rely on plant air pressures to maintain properly working equipment and systems. One of the most common problems affecting processing plants that utilize compressed air systems is the ability to maintain reliable air pressure throughout the distribution system. Insufficient air pressures may be due to undersized distribution piping, but it’s more commonly found that the cause ...

  • Top 10 Valve Considerations for Pressure Management Zones/DMA’s

    For basic pressure management or more advanced modulating pressure management, water suppliers create a network of District Metered Areas (DMA’s) or smaller, more manageable pressure management zones. The DMA or pressure zone gives the ability to measure flow and control pressure, when a Pressure Reducing Valve (PRV) ...

  • Cycle Stop Valves verses Constant Pressure Pumps case study

    The newest innovation in pump control technology is "constant pressure valves". The name "constant pressure valve" was coined several years ago by Cycle Stop Valves or CSV. Some people would like you to believe that variable speed pumps, VFD, or so called "constant pressure pumps" are the most modern pump control system. In reality VFD was introduced in 1968, and because of the laws of physics, ...

  • Reduction in water losses in water distribution systems using pressure reduction valves

    Water loss is a phenomenon frequently observed within water distribution systems (WDSs), that is considerably worsened by an excessive pressure throughout the network. As an alternative option to pipe replacement, the use of pumps working as turbines, throttle control valves (TCVs), or pressure reduction valves (PRVs) can be used to reduce leakage. For a preassigned number of these devices, ...

  • Replacement Fill Control Valves with Electronic Flow and Metering Improve Pressure, Stop Leakage and Prevent Valve Failures

    The City of Modesto, California is situated 90 miles east of San Francisco and has approximately 200,000 residents relying on 200,000 of gallons of water a day. The City needed to upgrade three water storage tanks that hold approximately 750,000 gallons each. After years of using motor operated valves to fill water storage tanks, the city recognized that there were just too many problems. ...

  • Everything Depends on Pressure And Maintenance

    Energy and cost efficiency of biological treatment plants Every biologically working sewage plant needs a compressed air station for the oxygen supply of the aeration basin. This station only works at the highest possible energy efficiency level if excessive plant pressure through the subordinated system, excessive intake temperatures due to insufficient aeration and deaeration, and ...

  • ELECTRONIC WATER TREATMENT REDUCES FOULING AND CORROSION IN PIPELINES

    Increasing pressure loss in the pipeline is often caused by scale corrosion or product fouling of the internal surfaces. This condition slows transmission and distribution capacity, and can require more than just routine maintenance if it remains unaddressed. Interior corrosion, fouling and leakage in pipeline systems will adversely impact bottom-line operations. ...

  • Implementation of pressure reduction valves in a dynamic water distribution numerical model to control the inequality in water supply

    The analysis of water distribution networks has to take into account the variability of users' water demand and the variability of network boundary conditions. In complex systems, e.g. those characterized by the presence of local private tanks and intermittent distribution, this variability suggests the use of dynamic models that are able to evaluate the rapid variability of pressures and ...

  • Dealing with Cavitation in Control Valves

    Cavitation consists of rapid vaporization and condensation within a liquid. When local pressure falls to vapor pressure (approximately 0.25 psi / 0.018 bar absolute for cold water), vapor bubbles are formed and when these bubbles travel to an area of higher pressure, the bubbles collapse with phenomenal force and great localized stress. It is the violent collapse of these vapor bubbles near valve ...

  • Sanitary Valve Installation

    1. Control valve seal design. The single seat valve can reach less than 1 drop per hour of leakage. The double seat valve is difficult to seal. Therefore, switching to a single seat valve must be an optional choice. 2. Large amounts of high pressure fluid trapped between the shut-off valves may present considerable force and ...
