1.3. VALVES
A valve is a mechanical device that controls the flow of fluid and pressure within a system or
process. A valve controls system or process fluid flow and pressure by performing any of the
following functions:
Stopping and starting fluid flow.
Varying (throttling) the amount of fluid flow.
Controlling the direction of fluid flow.
7
Regulating downstream system or process pressure. Relieving component or piping over
pressure.
Because of the diversity of the types of systems, fluids, and environments in which valves must
operate, a vast array of valve types have been developed. Examples of some common types of
valves are globe valve, gate valve, ball valve, plug valve, butterfly valve, diaphragm valve, check
valve, pinch valve, and safety valve. Each type of valve has been designed to meet specific needs.
Valves are basically made up of Carbon Steel, Stainless Steel, Haste alloy, Alloy 20, Forged steel,
Polypropylene etc.

Main Parts of a valve are:
• Body: The outer casting of a valve.
• Bonnet: It is the cover for opening the valve body.
• Trim: It includes disk, seat, stem and sleeves.
• Actuator: It is a mechanism or device to automatically or remotely control a valve from
outside the body.
• Packing: It is provided to prevent leakage between stem and bonnet.
• Ports: These are the passages that allow fluid to pass through the valve.
Classification of valves:
Regulating valve: Globe valve, needle valve, butterfly valve, ball valve, plug valve and
diaphragm valve.
Back Flow Prevention Valve: Check Valve.
Stop (Isolation Valve): Gate valve, Globe valve, ball valve, butterfly valve, plug valve,
diaphragm valve.

A mechanical seal is a sealing device which forms a running seal between rotating and stationary
parts. Mechanical seal helps join systems or mechanisms together by preventing leakage (e.g. in a
plumbing system), containing pressure, or excluding contamination. The effectiveness of a seal is
dependent on adhesion in the case of sealants and compression in the case of gaskets.
Mechanical seals may be pusher seals, non-pusher seals, unbalanced seals, conventional seals,
balanced seals and cartridge seals.
A stationary seal may also be referred to as 'packing'.
Advantages of mechanical seals over conventional packing are as follows:
Zero or limited leakage of product (meet emission regulations.) Reduced friction and
power loss.
Elimination of shaft or sleeve wear.
Reduced maintenance costs.
Ability to seal higher pressures and more corrosive environments.
The wide variety of designs allows use of mechanical seals in almost all pump applications

CHAPTER 3
3.1. TASK PERFORMED
14
The hotels that we visited mainly uses metal valves such as ball valves, butterfly valves, check
valves, globe valves etc with size varying from 15mm to 80 mm. The mechanical seals are basically
used in pressure booster pumps and fire fighting pumps. During our visits we basically introduced
valves and mechanical seals and handed over our catalogues to the concerned maintenance person
of the hotels. Their enquiries are being collected and are taken into consideration by the respective
persons of our company.
During our visits to the hospitals we find that they usually have requirements of metal valves like
gate valves, ball valves, butterfly valves and the valves that are used in fire fighter pumps. So we
handed over our catalogues of metal valves and mechanical seals to the respective persons of their
maintenance department.
CHAPTER 4
4.1. CONCLUSION
It has really been a great experience to work with SM Flow & Controls (P) Ltd. The company has
given us a platform where we could enrich our knowledge both theoretically and practically
regarding the mechanical seals and valves and the working principle of the various parts and its
importance not only in industrial field but also in the domestic uses of our day-to-day life. We are
really glad to work as a trainee with the company; also we are thankful to the company for giving
us such an opportunity to work with them.
15
With time to come we thus hope that SM Flow and Controls achieve their vision and mission in
every possible way.
