ENERGY DISSIPATING VALVES - Ross Valve

1 595 TROY NY 12180 DISSIPATINGVALVESMODEL MOVSAFELY REDUCES PRESSURE IN EXTREME 595 TROY NY 12180 your head undercontrol with high velocity and high pressure drop applications,you want a Valve that works. The Ross model MOV(Multiple Orifice Valve ) is your answer. Elegant in design,the MOV effectively controlsflow and pressure in demanding Valve applications. If you encounter high pressure drops, high velocities, pressure surging, cavitation, or other demanding conditions, insist on the best Valve for the application - Ross effectiveness of the MOV s operation is derivedfrom its simple dual-plate design. A large number of strategically placed engineered orifices evenly distributethe flow stream over the entire face of the upstream valveplate.

2 Based upon the desired flow rate, the flow media isdivided into multiple jets, creating the desired throttlingeffect. Orifices align for higher flow rates. Flow arearestricts for lower flow rates. Control of the Valve and itsflow is determined by the linearplate and its relative posi-tion to the fixed plate. As the Valve works, the uniform jetconfiguration suppresses vibration, pressure fluctuations,cavitation, and , hydraulic, and electronic actuators areavailable to operate the MOV. Combinations of these actuator types are also available for specific design of the Ross MOV also provides otheradvantages. Its cavitation inception figures are more desirable than conventional VALVES . Tapered holes, counterbored holes, and exotic material of construction are utilized to assure that cavitation does not create a hazardwithin the Valve .

3 For severe cavitation applications, specialplates and additional enhancement features are available tooptimize the Valve s saving features typical of a butterfly Valve ,versatility of control actuators typical of a ball Valve , andoperating features of a conventional control Valve makethe MOV the Valve of get control. Ask about the Ross model MOV. It sthe answer to controlling your high-pressure of Ross Model MOV Peace of mind for the operator of high-velocityand high-pressure drop situations. Available as manual, hydraulic and electricallyoperated control VALVES . High-velocity dissipation design with one fixedand one linear moving perforated plate. Flexible mounting design compatible with horizontal or vertical pipe installations.

4 Unique bearing design of the linear plateallows bi-directional operation and eliminatesany possibility of misalignment. Field-replaceable seals for easy maintenanceand operational efficiency. Configured to open, close, or hold position during a power failure. Dielectric links protecting all parts and assuringeasy maintenance. Ross industry-first taper ring adjustmentdevice to regulate desired low flow leakagerate (Note: the MOV is not recommended forbubble tight shut off applications). Same rugged construction as all Ross VALVES ,with design to testing done in-house. Capable of high capacity flow applicationswith total orifice area in excess of 30% of thepipeline flow InstallationsThe Ross Model MOV can be controlled by acombination of manual, hydraulic or electricalactuation packages.

5 It is suitable for a range ofapplications, including: Industrial flow Cooling and mixing systems Water supply and distribution systems Headworks of water treatment plants Flow relief for pump and turbine units Water intake or discharge of dams Laboratory test rigs Replacing damaged throttling butterfly VALVES Replacing damaged throttled ball valvesPROUDLY MADE INUSANote: Renderings shown are for reference only and are subject to change at any time.

6 Anti-cavitation enhancing orificesincorporated into the fixed downstream plate. Jet enhancing upstream plate orifices for severe service conditions. Capable of controlling transient and reverse flow conditions. Hydraulic anti-lift flow design (typical of butterfly VALVES ). Field-replaceable stem packings forlow friction operation and efficientmaintenance. Rugged construction with hardenedthick plates, heavy duty shafts andseals. Compact size and lay length. Small actuation packages available. Full control packages OPEN50% OPENCLOSEDO rifices in plates are completely allignedOPERATIONThe Ross Model MOV is based on bi-directional operating principles andcontains one fixed (downstream) Valve plate, and one linearly moving(upstream) Valve plate.

7 Both plates have matching orifices at a large numberof engineered locations. These orifices divide the flow into jets that dissipateenergy in a short linear distance.

And no wonder, because wecontrol the process in-housefrom start to finish. After designing the components,molds are made. We then startwith the finest raw materials. All metals are poured in ourown New York based parts are machined tospecs. Then each Valve is meticulously assembled, pilotvalves and controls are set, and the Valve is wet testedunder the designed operatingconditions. When you receiveyour new Ross Valve , you cancount on its ability to performfrom start to George Ross founded our company in 1879,he made a product designed to last.
