MSCA are check valves with a built-in stop valve function. MCHV are check valves only. MSCA / MCHV are available in angle way versions. The valves are designed to open at very low differential pressures, allow favourable flow conditions and are easy to disassemble for inspection and service.

2.  Maniks is the most reputed Indian brand with a
history of 30 years for manufacturing reverse jet
pulse valves used in bag-filter applications and
the sequential timers used in conjunction with
them. These are used in dust collector equipment
for cement, steel and such other industries. The
company was started by Mr. Shekhar Kulkarni, an
IIT Mumbai alumnus, with a vision to substitute
imported products with Indian make products.
The primary aim was to produce reliable
products with excellent quality and service.

4.  What is Stop Check Valves ?
• MSCA are check valves with a built-in stop valve function. MCHV
are check valves only. MSCA / MCHV are available in angle way
versions.
• The valves are designed to open at very low differential
pressures, allow favourable flow conditions and are easy to
disassemble for inspection and service.
• The MSCA is equipped with vented cap and has internal back-
seating enabling the spindle seal to be replaced whilst the valve
still under pressure.
• Laser cut V-ports provide excellent opening characteristics
(MSCA / MCHV 50-125).

7.  Working of Stop Check Valves
• The valve must be mounted vertically with the cone
downwards. The valve is designed to resist very 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 installation instructions
for MSCA-X/MSCHV-X. If cold refrigeration oil having
low viscosity enters and settles in the damping
chamber, problems with the check valve may arise.
Consequently, it may be necessary to modify the valve
for more viscous liquids by enlarging the hole to the
damping chamber.

9. Packing gland (MSCA-X) :
The "full temperature range" packing gland is the
standard for the entire MSVL platform.
This ensures perfect tightness throughout the whole
temperature range : –60/+150°C (–76/+302°F).
Damping chamber :
The chamber is filled with refrigerants (gas or liquid),
which provides a damping effect when the valve
opens and closes.
