memory stop principle a valve capable of being set to a desired degree of opening, locking that position with a memory stop to ensure the position can be retrieved exactly after the valve has been closed.
bypass duty 3port In the UK the Double Regulating Valve [DRV] is primarily used to create flow resistance or a pressure drop in the by-pass of a 3-Port mixing or diverter valve or for simulating a load for a future loop.
no flow measurement Keep in mind that this balancing valve doesn’t provide any flow measurement.
butterfly memory stop ref For line sizes from DN 65, Butterfly valves that have been fitted with a memory stop can offer the same functionality as the traditional globe design while being lighter, smaller, easier to install and less costly.
vodrv definition The DRV is sometimes referred to as “ Variable Orifice Double Regulating Valve ” [VODRV].
vodrv kv method The flow rate is calculated using the Kv value for each handwheel setting and the Δ P across the valve.
vodrv accuracy ref The measurement accuracy may be adversely affected by this principle by plus or minus 15%, when close to the minimum set point (25% open as per CIBSE guideline).
vodrv unidirectional The valve is unidirectional and the direction of the flow arrow on the valve body must be respected.
fodrv definition The Fixed Orifice Double Regulating Valve [FODRV] is also referred to as Commissioning Valve or Commissioning Valve Set.
fodrv accuracy ref The accuracy of this type of valve is typically + 5%, depending on the opening position.
venturi pressure recovery The FODRV with venturi minimises turbulence and recovers a significant proportion of the pressure loss after flow has passed through it, and can be close coupled, which makes the venturi FODRV suitable for systems with low differential pressure.
picv variable flow trend Commissioning Valves are not suitable for variable flow and have been replaced by PICVs.
bypass future load Install a DRV bypass between flow and return to simulate future system load.
y pattern globe body Typically this valve is a Y pattern globe valve arranged in this way to present the smallest pressure loss to the system when fully open.
double regulating meaning The description DOUBLE regulating means that it has a feature whereby you can set the position that the valve is to operate at in such a way that you can still close the valve for maintenance purposes.
resistance reduces flow Adjustment of this valve will add resistance to the system and hence reduce the flow.

Source 2 — memory stop principle Memory stop/Sealing locking The valves are equipped with an adjustment position memory system that, after full closure which can be necessary for various reasons, allows easy re-opening at the initial position.
Source 2 — setting seal locking There are two holes on the knob that can be used to seal (5) the setting position to avoid or detect any tampering over time.
Source 2 — presetting method Knowing the value of the pressure drop p that needs to be created by the valve with a certain flow rate G, you can obtain the adjustment position number for the knob (PRESETTING).
Source 2 — adjustment scale clockwise turn of the knob moves the red indicator by one step, from position 0 (valve closed) to position 6 (fully open valve). In addition, the decimal graduations of the black micrometric scale enable further refining of the adjustment.
Source 2 — installation clearance The balancing valves must be installed in such a way as to ensure free access to the pressure test ports, drain cocks and the adjustment knob. The valves can be fitted on either horizontal or vertical pipes.
Source 3 — fodrv definition is a fixed orifice double regulating valve (FODRV) which uses a venturi to measure the flow of liquid passing through the valve.
Source 3 — venturi definition A venturi is a fixed orifice device consisting of two different diameters with a tapered section between them. The smaller diameter is referred to as the throat.
Source 3 — venturi upstream The venturi is located upstream of the double regulating valve which provides stable flow measurement during flow regulation.

범위·출처 비고

measurement accuracy Measurement accuracy: reference VODRV principle can drift plus or minus 15% near the minimum set point (25% open per CIBSE), while the tenant page presents a calibrated handwheel with no stated measurement accuracy - accuracy class is unstated on the tenant page.
line size alternative Line-size alternative: reference practice offers butterfly valves with memory stops as functionally equivalent from DN 65 upward (lighter, smaller, cheaper), while the tenant globe-design DRV lines run DN65 to DN600 - the globe-versus-butterfly split is not represented on the tenant page.
system trend positioning System-trend positioning: reference guidance states commissioning valves are not suitable for variable flow and have been replaced by PICVs, while the tenant page positions static balancing DRVs without the variable-flow caveat.
peer pressure material mix Peer pressure/material mix: peer executions offer PN20 brass screwed FODRV lines and PN16 flanged ductile-iron VODRV lines, versus the tenant PN25 bronze and PN16 ductile-iron lines - peer brass PN20 sits between the tenant bronze PN25 and ductile PN16 bands.
