5.  What is Maniks Stop Valves?
 A valve opened or closed at will (manually) for preventing or
regulating flow (of a liquid in a pipe) is called as stop valve.
Simply a stop valve is any sort of valve type that completely
stops the flow of liquid flow through a pipe.
 Stop valves is mainly used in plumbing or industrial
applications to shut off the flow of (hot or cold) water to a
plumbing fixture, such as an icemaker, toilet, faucet,
dishwasher etc. Stop valves also allow performing routine
maintenance like filter change and drain cleaning, and also to
replace the entire design or appliance.

6.  Stop Valve Function :
 Maniks manufactures Stop valves (MSVA) in angle-way
and straight-way types with a Standard neck (MSVA-S).
 The stop valves are manufactured to meet all the
refrigeration and industrial application requirements of
customers and are designed to give continuous flow
characteristics which are easy to repair and dismantle the
valve whenever necessary.
 The stop valve is designed to provide perfect closing and
ensure a high system pulsation and vibration, which may be
present specifically in the discharge line of the system.

Valve Cone:
The valve cone may be turned on the spindle. Thus there will be no friction in
between the seat and the cone when the valve is in operation (closed and
opened) and the special design will avoid the cone spin due to pulsation and
vibration, when the valve is in open position. Teflon tightening ring is used
which provides perfect sealing, with minimum closing force.
Spindle:
Made of polished stainless steel, ideal for leap seal sealing.
Packing gland:
The low temperature packing gland provides a perfect tightness in the range: –
60/+150°C (–76/+302°F). The packing glands are embedded with a scraper ring
that is used to prevent penetration of dirt and ice into the packing gland.

9.  It is recommended that stop valves should be installed in
the direction of flow of liquid indicated by the arrow on the
valve body. These valves can be installed in the reverse
direction but this may slightly reduce the Kv-value (Cv-
value). The Maniks stop valve is manufactured to provide
high internal pressure. However, the piping system typically
should be designed reduce the risk of hydraulic pressure
caused by thermal expansion and to avoid liquid traps.
 For further information refer to installation instructions for
MSVA.
