  • Valves in Water System of Heating Air Condition

    Common valves in water system of heating air condition include gate valve, globe valve and butterfly valve.   Gate vale For its moderate length, rotary adjusting rod and good regulating performance, gate valve is widely utilized in large caliber pipes.   Globe valve Globe valve is suitable for small caliber pipes for its long length, ...

  • 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, ...

  • Abha water utility comes out on top with automated control valves

    Abha is a small modern city in the fertile mountains of southwestern SAUDI ARABIA. Its cool summers make it a popular destination for tourists, but in general the population hovers around 250,000. The city has a new reservoir on top of a hill that releases water through 6 km of piping down to its main Noaman reservoir. The top tank is 100 meters higher than the lower tank. This makes for a great ...

  • Asset Management in the Water Industry - the Valve Actuator`s Perspective

    The water and effluent treatment industries have recognised the benefits of effective asset management resulting from the gathering and analysis of accurate and relevant data from out in the plant. The data identifies the condition of the equipment and gives the operator a real-time view of the plant. Monitoring the data over time enables the operator to avoid unplanned interruptions and plan ...

  • Features of Sanitary Butterfly Valves

    The disc and the sanitary butterfly valve body can be in spheroidal cast iron or in steel. At this valve, when it is in the open position, small localized losses of pressure occur, while strong turbulence and vibrations are created in case of partial closure. Therefore, it is not very suitable for regulation. The maneuvers of the small diameter butterfly valves can be done ...

  • Bringing Life To The Dead – How Halifax Water Unlocked The Value Of Valve Inoperability

    Wachs Water Services recently gave the Canadian municipal water sector an impressive demonstration of how their unique approach, field experience and mechanical advantage could coax non-functioning valves back to operational life. Halifax Water recently found itself in a jubilant mood after freeing up a significant amount of dollars originally earmarked for valve replacement within its ...

  • Valuing Global Valves

    Control valve solves flow control & pressure challenges Donnacona, Quebec, Canada, is an industrial town just west of Quebec City. The town’s water treatment plant was built in 1969 and has since undergone three major retrofits: new high-pressure pumps and an electrical upgrade in 1995; a filter bottoms change in 2000; and a river water intake upgrade in 2005. The plant includes ...

  • Rotork’s RHS solves valve access issue at water treatment plant

    Recent rehabilitation at the drinking Water Treatment Plant #2 in Olathe, Kansas, USA, has included the installation of Rotork IQ3 intelligent electric valve actuators to replace electric actuators from another manufacturer. In the gravity filter plant, 18 butterfly valves are situated in an area beneath a walkway which made it difficult to access and operate the old actuators. With the new ...

  • Giving Valves a Workout

    Manual valve exercising is a time-consuming process, and one that poses risks of injury to employees and damage to valves. Valve-exercising technology is designed to automate the process, so that employees do not subject themselves to the strain of turning large or stuck valves, and so that only appropriate levels of torque are applied to valves. Automationhas the added advantage of enabling easy ...

  • Healthy Control Valves

    A simple maintenance routine can help ensure trouble-free valve operation. Whether the control valve in your system is the first one that has required maintenance or if you are experienced with maintaining multiple valves in your system, some simple guidelines can help keep them operating at optimal performance. Physically checking all valves at least every 12 weeks is important, assuming that ...

  • 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 ...

  • Water hammer suppression for long distance water supply systems by combining the air vessel and valve

    In long distance water supply projects, the air vessel is an effective and reliable protection measure to control water hammer. Although it can effectively eliminate water hammer during the process of hydraulic transient, the volume of the traditional air vessel is large due to the long distance pipeline, resulting in high investment. In this paper, based on the analysis of the transient in ...

  • 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 ...
