Terminator® Commissioning Valves
Marflow Hydronics’ Terminator® is a range
of manual balancing valves (also known as
commissioning valves) which comprises of a
standard flow and low-flow combination venturi
and regulating ball valve as well as a standalone
regulating ball valve with memory stop and position
indicator for installation on by-pass duty.
The Terminator range includes:
• TCV 90 – Standard flow commissioning valve, size
range 15mm (½”) to 50mm (2”)
• TCV94 – Low flow commissioning valve, available in
15mm (½”) size only
• FR59 – Filtermate® Regulator ball valve with
memory stop and indicator
Features & Benefits
• Quarter Turn
• Accuracy of flow measurement to within +/-3%
• Regulation, isolation and flow measurement in one
• Triple sealed stem protection
• Internal spindle assembly prevents stem blow out
• Double body connection seal
• Union connections
• Air vent tapping in the body
• Air vents available as an accessory
• Threaded end connections ISO 7/1 Rc – (BSP
female taper thread)
Terminator® Standard Flow
The Terminator® uses a regulating ball valve with
an integrated venturi for flow measurement. This
design combination ensures high accuracy of flow
measurement and balancing across all valve settings.
Terminator® Low Flow
The low flow Terminator® offers high control and
regulation when dealing with low design flow rates.
The Terminator Profile balancing valve has been
designed to add resistance and so control the
flow as soon as the handle is turned. The
result is that the relationship between the
closing of the valve and the resistance is
virtually linear over the complete operation
of the valve.

TICV
The interchangeable valve is a single DZR brass
body valve which includes venturi flow measurement,
complete with test points. Connections are
BSP female threads. Venturis are also easily
interchangeable and available in a number of sizes
from 3-12mm and the body is available in ½” and ¾”.
FMV
The flow measurement valve is a single DZR brass
body valve combined with isolation, which includes
venturi flow measurement, complete with test points.
Connections are BSP female threads. Venturis are
also easily interchangeable and available in a number
of sizes from 3-12mm and the body is available in ½”
and ¾”.
Features & Benefits
• Easily interchangeable venturi
• Isolation and flow measurement in one
• Air vent tapping in the body
• Air vents available as an accessory
• Threaded end connections ISO228 G (BSP female parallel thread)
Filtermate® Regulator
The Filtermate regulator is combined isolation and
regulation to guarantee excellent balancing when
manual control is required.
Venturis
A venturi is a device for measuring flow either
integrated into a commission set or used
independently in a circuit or sub-circuit. An added
benefit of using a venturi is that a significant
proportion of the pressure loss is recovered after flow
has passed through it.
Typically, venturis give a higher signal for
a given flow rate and have much better
pressure recovery than other measuring
devices, such as orifice plates, especially at
lower flow rates. High pressure and energy
recovery makes the venturi suitable where
only small pressure head is available.
Uniquely, the Terminator® TCV series is offered with a
selection of venturis dependant upon the flow rates
required. The standard flow TCV 90 range has an
option of two venturis in each valve size from 1” to
2” (covering a multiple range of Kvs from 3.04 to 42)
whilst the TCV 94 Low Flow valve has options for three
venturis (covering Kvs from 0.36 to 1.38).
