Pressure Reducing Valve

Brass MICRO-PRV is and ideal Pressure Reducing Valve for protecting electric hot water storage heaters, household appliances and vending machines. Body & Stem : CW617N (Brass), O-ring : EPDM, PRV can be set from 1 to 4 Bar, Maximum Inlet Pressure : 16 Bar.

Application:

• Pressure reducing valves of this type protect installations against excessive pressure from the supply. They can be used for household, industrial or commercial applications within the range of their specification.
• Reduction of the operating pressure and maintaining it at a constant level minimizes flow noise in the installation
• The set pressure is also maintained constant, even when there is wide inlet pressure fluctuation.

• Takes Less Space, easier to fit, less obtrusive underneath hot water storage heaters.
• Factory preset at 3 bar ±0.5, you can change the setting from 1 to 4 bar.
• The valve system design and types of seals used ensure operation with minimal noise
• The Redubar does not require any special maintenance

• Pressure Adjusting Range : 1.5 ~ 6 Kg/Cmsq
• Maximum Pressure : 16 Kg/Cmsq
• Maximum Temperature : 70°C
• Connection : Screwed End (BSP)

LEHRY PRESSURE REDUCING CONTROL VALVE, DUCTILE IRON, F/E. PN.16, Body: Ductile Iron (ASTM A536), Stem: SS, Seat: Brass, Spring: SS 304 Disc Retainer: Brass, Pressure: PN16, Pilot: SS Pilot System: 1.5 ?? 6 Bar (Low),: 6 ?? 12 Bar (Standard), Ends: Flanged End as per PN 16 LEHRY Pressure reducing valve, is used to reduce a higher fluctuation upstream pressure, to a constant desired downstream pressure, through an adjustable pilot system. The downstream pressure is maintained a constant, regardless of changes in upstream pressure and flow.

It is controlled by a normally open, pressure reducing pilot designed to:

• Open (allowing fluid out of the main valve cover chamber) when downstream pressure is below the adjustable set point
• Close (allowing fluid to fill the main valve cover chamber) when downstream pressure is above the adjustable set point. A decrease in downstream pressure causes the valve to modulate toward an open position, raising downstream pressure. An increase in downstream pressure causes the valve to modulate toward a closed position, lowering downstream pressure

Working Principle : - When downstream pressure is lower than setting pressure, pilot M Opens automatically, the pressure contained in the by-pass circuit doesn't apply any force on the membrane of main valve A. Thus the closing system is released and lifted. The valve throttles to open position to increase downstream pressure to the desired level. When downstream pressure is higher than setting pressure, pilot M is closed automatically, the pressure contained in the membrane of main valve A. Thus the closing system drop down and the valve throttles to closed position to reduce downstream pressure to the desired level. ??? Control and Maintain a preset pressure. ??? This valve prevent over pumping of a pump if the system demand exceeds the pumping capacity. The upper reaches of the pressure range: 0.00-2.76 Bar, 1.72 - 8.62 bar, 6.89 - 17.23 Bar, 17.23 - 27.23 bar

Cavitation Guide Chart After selecting the valve size, locate inlet and outlet pressure on this chart. If the intersection point falls in the shade area, cavitation can occur. Operation of valve continually in the cavitation zone should be avoided. Anti-Cavitation Solution The Anti-Cavitation mold is designed for application where there is a high potential for damage from cavitation, which provides optimum internal pressure control through a unique anti-cavitation trim design.
