Stop Valve-Types and Working stop valve final.output | Page 2

Versions with Standard neck (SVA-S).
s These valves are exceptionally intended to meet all modern refrigeration
application prerequisites and are to provide favorable stream qualities and
are anything but difficult to decimate and repair when vital. They support is
very simple consequently Stop valves are favored by numerous refrigeration
applications. The stop valve cone is intended to guarantee consummate
shutting and withstand a high framework throb and vibration, which can be
available particularly in the release line.
Design of Stop Valve (SVA)
Stop valve is designed with prospect to use in industrial refrigeration system
it consist of three major parts namely valve cone, spindle, packing gland the
brief description is given below.

•
Valve Cone :
The valve cone can be turned on the axle. Along these lines there will
be no erosion between the cone and the seat when the valve is opened
and shut and the extraordinary plan will maintain a strategic distance
from cone turn because of throb and vibration when the valve is in
vacant position. A Teflon fixing ring furnishes consummate fixing with
least shutting power.
Spindle:
The spindle is made up of polished stainless steel, ideal for leap
seal sealing.
Packing gland:
It is a low temperature packing gland that ensures a perfect
tightness in the range: –60/+150°C (–76/+302°F). The packing
glands are equipped with a scraper ring to prevent penetration of
dirt and ice into the packing gland of the stop valve.
Features of Stop Valve
•
•
• Applicable to HCFC, HFC, R717 (Ammonia) and R744 (CO ).
Can be used in chemical and petrochemical applications.
Modular Concept :
•
• Each valve is available with several different connection types and sizes.
Possible to convert Standard neck stop valve (MSVA-S) any other product
in the MSVL family (regulating valve, stop check valve, check valve or
strainer) just by replacing the complete top part.
