Introduction:-
A valve is just a tool that directs or regulates flow by gap, closing or partly obstructing 
passageways. Valves square measure instrumental in everything from pumping soap out of a 
dispenser to beginning a jet.
You can’t be a pipe knowledgeable while not being associate degree industrial valve and fitting 
knowledgeable, as well. Without valves, there would be no control of your pipe flow. 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 machine-driven, 
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 etc.
You can’t be a pipe expert without being an industrial valve and fitting expert, as well. Without 
valves, there would be no control of your pipe flow. Here are some of the types of valves described 
lets have looked on it.
1) Gate Valves
Gate valves, the most common type of valve in the industry, are 
valves that open by lifting a gate out of the route of the fluid. 
Gate valves square measure designed to be absolutely open or 
closed; they're frequently used as a block valve for analytic pipe 
systems.
When a gate valve is open, there's no obstruction within the flow 
path leading to little or no friction loss. Gate valves square 
measure used once a straight-line flow of fluid and minimum 
restriction is desired.
These are often controlled by a hand-wheel, air powered 
diaphragm, electric motor, or a piston actuator.
2) Globe Valves
Globe valves square measure used for regulation flow in 
a very pipeline, rather than having the “all or nothing” 
perform of a gate valve. Globe valves regulate by the 
position of a movable disk (or plug) in relation with the 
stationary ring seat.
A globe valve could have ports that run straight across, 
or could also be pointed at associate degree angle. This 
type of angulate provide valve is often used for 
corrosive or thick, viscous fluids that tend to solidify. 
Having shops on associate degree angulate provide 
valve that time downward helps the fluid to empty off to 
forestall preventive  and corrosion. 

3) Pulse Diaphragm Valve:
Pulse Diaphragm Valve it is to blame for continuous flow of air 
and collect dust in a very bag filter. 
Pulse Diaphragm Valve has only one moving half known as 
Diaphragm. Its distinctive inelastic style provides quick opening 
and shutting of the pulse Valve with saving of compressed gas. 
Long life, High flow and quick diaphragm operation turn out 
reliable and economical operation.

4) Needle Valves
The needle valve is actually a variation of the 
world valve used for terribly fine management 
of flow. Needle valves contain a slender, 
tapered plug, as opposed to the globe valve’s 
larger and less accurate disk.
5) Butterfly Valves
A valve comprising of a pivoting round plate or a 
couple of pivoted half-circle plates appended to a 
transverse shaft and mounted inside a pipe so as to 
manage or forestall stream. 
Butterfly valves work comparatively to ball valves. 
Pivoting (rotating) the handle, either physically or with 
a pneumatic framework, turns the plate opposite or 
parallel to the stream of the liquid.
6) Check Valve
Check valves, also known as NRVs (non-return valves), 
permit fluid to flow in one direction only. Their purpose 
is to prevent backflow. 
There square measure many kinds of “stoppers” that stop 
flow under control valves. Ball check valves and piston 
check valves operate by requiring a minimum amount of 
inbound flow pressure; backflow is not forceful enough to 
lift the ball or piston back up to travel the other direction. 
Flow in a very swing check valve pushes through a 
hinged flap that solely opens in one direction, reassuring 
the fluid cannot travel backwards.
7) Hydraulic and Pneumatic Valve
A solenoid valve is an electrically enacted valve, regularly used 
to control the stream or heading of air or fluid in liquid power 
frameworks. Solenoid valves are utilized in both hydraulic 
pressure and pneumatic pressure power system, and regularly in 
either poppet or spool arrangements.
8) Pilot-operated valves
Pilot-operated pneumatic solenoid valves, or indirect solenoid 
valves, have two connected chambers and use a pilot hole in a 
diaphragm (or cover) to indirectly control the pressure of the 
media. Once the solenoid valve is energized, the pressure 
difference controls the lift of the membrane and allows the gas 
to flow in a single direction. These types of pneumatic control 
valves are suitable for a high flow rate at high pressures with 
lower power consumption. A minimum pressure differential is 
required across the valve to keep them either open or closed.
