Introduction:-
Valves are used to handle a wide variety of functions in controlling the flow of liquids and gases. 
With so many options available, it’s important to look at all of the factors to ensure you are selecting 
the correct valve for your application.
Valves are a automaton that helps in dominant and reducing the flow of liquids, gases, oil, vapors 
along with that they are used in various types of pipe system to handle pressure. Valves are one of 
the most important components of all manufacturing and technological companies; so valve 
manufacturer are in high demands as they play a very crucial role in all types of industrial, 
commercial, and even residential purpose that’s why need of industrial valves is drastically 
increasing.
Maniks has developed Pulse Diaphragm Valve and pulse jet valve for reverse pulse jet bag filters, 
offering precisely engineered valve of market need. Pulse Diaphragm Valve has just one moving 
part, the Spare diaphragm. The distinctive inelastic construction provides quick gap and shutting of 
the valve. The high speed operation besides saving of compressed air, helps to provide shock air 
wave for dislodging of dust from filter bags. High flow, long life and quick diaphragm action turn 
out reliable and economical operation.
Advancement in technology also led an enhancement in valve manufacturing which has many 
applications in day to day life as well as industries. These valves embrace automatic, manually 
operated, pneumatic or electric type. Thus selecting the appropriate valve is very much essential for 
your organizations overall productivity, cost efficiency, reliability, durability, high performance, 
corrosion resistance, long life
1. Application Conditions
The selection of the correct valve sizing is the most 
important step in selecting the right valve for your 
application. An improperly sized valve can cause 
operation issues within the valve or elsewhere in the 
system. 
In addition to this, determine the temperature, pressure, 
and flow rate that your valve will be operating under. In 
most cases, metal valves can withstand higher 
temperatures and pressures than plastic ones.
2. Valve Operation
Valves are worked by fundamental solenoid pilot operator. At the point 
when the valve is charged, the incoming air above pulse valve is 
quickly exhausted causing fast opening of main diaphragm valve. When 
the pilot valve is discharged, air escapes through bleed hole of main 
pulse valve to adjust the diaphragm pressure and quickly closes the 
valve.
Maniks pulse diaphragm valves are operated by integral solenoid pilot 
operator. When the valve is energized, the trapped air above pulse 
diaphragm valve is quickly exhausted causing fast opening of main 
diaphragm valve. When the Pulse diaphragm valve is de - energized, air 
escapes through bleed hole of main pulse diaphragm valve is to balance 
the diaphragm pressure and instantly closes the valve.

3. Valve Function
Determine the need that your valve needs to fill. 2-way valves 
perform well for on/off control in a system, while 3-way valves 
can be used for on/off control, as well as for diverting or mixing 
media. Also, take note of whether your valve will be open or 
closed the most often. 
In order to extend the life expectancy, order a valve that is 
normally in that orientation and changes to the other direction 
when energized.
 
4. Actuation Method
Another consideration to be made is how the valve is to 
be operated. Identify if the valve will be manually hand-
operated or if the valve will need to be actuated to turn 
off and on automatically. 
If the latter is chosen, decide whether the unit is going 
to be used with an electric, pneumatic, or hydraulic 
actuator.
5. Maintenance Requirements
If maintenance needs to be done regularly, ball valves are a great option as 
they resist clogging and are one of the simplest valve types to service. Ball 
valves are also available in 3-piece configurations, which consist of two end 
caps and a body. This allows the main body section to be easily removed for 
cleaning without disconnecting the end caps from the pipe, preventing the line 
from being shut down during maintenance.
Maniks is the most reputed Indian brand with a history of 30 years for valve 
manufacturer of pulse diaphragm valve These are used in dust collector 
equipment for cement, steel and such other industries. Mr. Shekhar Kulkarni, 
was the founder of the company an IIT Mumbai alumnus, with a dedication to 
substitute branded products with Indian make products. The basic aim was to 
manufacture reliable merchandise with glorious quality and repair. Maniks 
produces a broad line of competitively priced Pulse diaphragm valves and 
valve control products, including: globe, butterfly, ball, manifold, actuators, 
and solenoid valves. Each valve sort encompasses a form of choices to satisfy 
specific application desires. Valve position indicators, valve positioners.
 
6. Media Type
The characteristics of the liquid or gas type being 
controlled will determine the valve material that should 
be used. When monitoring harsh or corrosive materials, 
polytetrafluoroethylene (PTFE) and perfluoroalkoxy 
alkanes (PFA) are great choices, as they are able to 
withstand these conditions. 
When monitoring pressurized gases, it’s important to 
use metal valves for the highest level of safety.
