Adjusted diameter ensures accurate body centering, eyebolts simplify installation,connection forelectrostatic discharge line,valve disk is centrally aligned and guided by ribs,hardened seat,disk and spring guides unaffected by dirt.
Please note:
Theselected non-return valve must ensure that the minimum volume flowrate keeps the valve disk in the open position (see Pressure Drop Chart/stable range).Valve construction is very robust,but they are not recommended for use on compressors or where pulsating flow exists. If in doubt please consult us and we will carry out the pressure drop calculation and select a suitable valve.

Important Notes
The equipment must be hooked up to the pipes as shown in the graphical representation. Please take the following items into consideration:
■A motive steam line must be available and connected (connection: female thread, 6 % (204号
■Avent linemust be available and connected (connection: female thread, 6 % (20号
Minimum filing head required between condensateoutletof the heat exchangerand the bottmof the equipment: 0 . 5 \mathfrak { m } ■An inlet line (min. length 2 . 5 \mathsf { m } ) or buffer reservoir (volume:3 I) is required.
■Maximum motive steam pressure,depending on design,is 6 or 13 barg.
Like any other industrial valve steam traps are subject to wear and their correct functioning can be impaired by precipitated solids and dirt deposits.
To assess the performance of a steam trap the following questions have to be answered:
·Does the steam trap work properly?
·If not, does the faulty trap cause loss of steam (leakage) or banking-up of condensate (obstructed discharge passage)?
Faulty steam traps are a major source of waste ina steam distribution system.A trap that is blowing live steam is the worst offender,but traps that are plugged or stuck closed can also be costly. The decreased plant efficiency due to loss of energy and additional make-upwaterresults in lost production.Furthermore,anincrease of pressure is liable to arise in condensate systems which will lead to difficulties at all locations where condensate is discharged. The magnitude of such a steam loss depends on the cross-sectional areaof the leakand,at thesame time,the amountof discharged condensate.Locationswhereonly smallamountsof condensateare formed and discharged,e.g.drainage points in steam lines and tracing systems,are particularly problematical.On the other hand, locations where relatively large amounts of condensate are discharged will not give rise to considerable loss of live steam because of the presence of a large volume of liquid.
Steam traps which are obstructed or stuck closed do not cause loss of energy and/or water but reduce-to a greater or lesser extent -the efficiency of heat-transfer equipment and steam users.And waterhammer caused by condensate banking-up leads to considerable physical damage in steamand condensate systems.
Experience shows that installations where no regular trap testingand servicing takes place havea failure rate of defective steam traps in the order of 1 5 - 2 5 % Regular maintenance and trap testing,which should be carried out at least oncea year,can strongly reduce the failure rate to 5 %
Test Systems
Steam traps can be tested during operation by using sightglasses, ultrasonic listeningdevices or level meters.
Sightglasses (VaposcopesType VK14,VK16) provideaneffective means of observing the flow of liquids in pipework.They are installed upstream of the traps,and allow the assessment of the traps by making their operation visible.
Level meters use conductivity readings to monitor steam trap performance.A test chamber with an integral level electrode is installed upstreamof the trap to detect anydefectivesteam trap.The corresponding output signal is displayed by the Remote Test Unit NRA 1-3x (remote monitoring).
ThesystemVKEcanmonitorall typesandmakes of steam traps to detect loss of live steam.The correct operation of RHoMBUSlinesteam traps type BK 45/46,MK 45,UBK 46 can be verifiedby using the compact-type level probes NRG 16-19,NRG16-27and NRG 16-28.The test station NRA 1-3x will evalute the data coming from the system VKE.
Anotherway to test traps is to use anultrasonic listeningdevice which detects the sound produced by steam flowing through the traps. Depending on the test system used the sound sensed by the device iseither graphically represented in the form of a curve (VKP 42)or indicated by the deflection on the scale of a meter (VKP 10). Whenusing the VKP1O,the field dataspecialist has toassess the indicator deflection and,consequently,the operation of the steam trap. The VKP 42, however,can directly track leaks associated with faulty steam traps and provides comprehensive reporting and a complete trap survey history.

The Lift Restriction for GESTRA Non-Return Valves
More efficient pumps and the requirement to minimize pressure loss in the installation often lead to oversized non-return valves.
As a consequence, the valve does not open completely, resulting in increased wear and, more often than not, annoying valve clattering.
Up till now the required volume flow of these nonreturnvalves could only be adjusted in certain cases byselecting a different size or changing the place of installation.
The lift restriction for GESTRA valves provides stable low-noise operation even with small flowrates.
For users who do not want to change their pipe layout or use smaller sizes but require a more stable operating mode we now offer a retrofitting set consisting of a stroke limiter and a spring cap.This mechanism reduces the volume flow for the necessary full opening as a function of the valve size by approx. 4 0 %
The lift restriction is available for non-return valves RK41,RK44,RK86 andRK86Ain sizesDN15 up to DN 100.
