RANGE ABILITY

The Inherent range ability of MSSet standard trims is as given under.

MAXIMUM RECOMMENDED VALVE BODY VELOCITY FOR LIQUID FLOWS

MAXIMUM RECOMMENDED VALVE BODY VELOCITY FOR GAS/VAPOUR FLOWS

The Inherent flow characteristic of a control valve is the relationship between the flow and the lift of the plug at constant pressure drop.The characteristic normally available are shown
as below.

LINEAR :-Flow is directly proportional to valve lift.

EQUAL%:- Flow change by a constant percentage of its instantaneous value for each unit of valve lift.

QUICK OPENING:- Flow increases rapidly with
initial travel reaching near its maximum at a low lift.

CONTOURED TRIM
(Metal to Metal & Soft Seated)

The Contoured Trim is the standard Top Guided top entry, which provides sure, economical Control for intermediate pressure drop service. A large diameter, precision machined plug and a pressed in, hardened guide bushing constitute the basic elements of a plug guidance system.
Contoured trim available for both modulating duty and on/off duty. The contoured trim configuration available for both metal to metal contact and soft seat to metal contact to give leakage rate in accordance to FCI-70.02 class VI (ANSI B 16.104 class VI.)

V – PORTED TRIM

V – PORTED TRIM

(Metal to Metal or Soft Seated)

• Ported cage trim is a heavy duty cage guided design with the
option of pressure balanced configuration.
• Choice of seal materials provides fluid compatibility.

MICRO FLOW SPLINED TRIM

(Metal to Metal or Soft Seated)

• This design of trim is a Seat guided arrangement having a very high
range ability and designed for the accurate control of minute flow rates.

LN1 Single Stage Low Noise

LN2 Double Stage Low Noise

LN3 Triple Stage Low Noise

LN4 Four Stage Low Noise

LOW NOISE TRIM
(Metal to Metal and Soft Seated)

• All the advantages of ported cage trims.
• Multiple drilled orifices of a special size and spacing resulting in reduced noise levels compared to
conventional valve trims.
• Added advantage on liquid duty valves by preventing cavitations damage.
• Low pressure recovery characteristic of LN1 suitable for flashing duty.
