6.  Regulating Valve Function :
 The valves are designed to meet the strict quality
requirements on refrigerating installations specified by
the international classification societies and are
carefully designed to present favourable flow
conditions and accurate linear characteristics.
 MREG-A and MREG-B are equipped with vented cap
and internal backseating enables replacement of the
spindle seal whilst the valve is active, i.e. under
pressure.

7.  Regulating Valve Design
 Connections:
 Butt-weld DIN (EN 10220) – DN 15 - 65 (3/8 - 2½ in.)
 Butt-weld ANSI (B 36.10 Schedule 80) – DN 15 - 40 (3/8 - 1½ in.)
 Butt-weld ANSI (B 36.10 Schedule 40) – DN 50 - 65 (2 - 2½ in.)
 Socket weld (ANSI B 16.11) – DN 15 - 40 (½ - 1½ in.)
 FPT inside pipe thread, NPT (ANSI/ASME B 1.20.1) – DN 15 - 32 (½ -
1¼ in.)
 Housing:
• Made of special, cold resistant steel.

Valve Cone:
•Versions – MREG-A with an A cone and MREG-B with a B cone. The A cone is
designed for expansion lines, while the B cone is designed for regulating purposes e.g.
liquid lines.
•The valve cone is designed to ensure perfect regulation and provide an extensive
regulating area. Irrespective of the refrigerant used, it is easy to obtain the correct
capacity. A cone seal ring provides perfect sealing at a minimum closing momentum.
•The valve cone can be turned on the spindle. Thus there will be no friction between the
cone and the seat when the valve is opened and closed.
Spindle: The spindle is made of polished stainless steel, which is ideal for O-ring
sealing.
Packing gland:
MREG-A and MREG-B
The "full temperature range" packing gland ensures perfect tightness in the whole range:
–60/+150°C (–76/+302°F). The packing glands are equipped with a scraper ring to
prevent penetration of dirt and ice.

9.  Install the valve with the spindle up or in horizontal
position. The flow must be directed towards the cone.
 The valve is designed to withstand high internal
pressure. However, the piping system in general should
be designed to avoid liquid traps and reduce the risk of
hydraulic pressure caused by thermal expansion.
 For further information refer to product instruction for
MREG- A and MREG-B.

10.  Refrigerants Applicable to HCFC, HFC, R717 (Ammonia) and
R744 (CO2). Can be used in chemical and petro-chemical
applications.
 Temperature range –60/+150°C (–76/+302°F)
 Max working pressure 52 bar g (754 psi g)
 Flow coefficients for fully opened valves from Kv = 0.15 to 80
m3/h (Cv = 0.17 to 92.5 USgal/ min).
