2. Chilled Water Piping Title Introduction to Chilled Water Piping System Types of Pipe Used Valves used in HVAC system Pipe fittings

3. Introduction to HVAC Chilled water Piping system 1 2 A water chiller, or chilled water system, is a cooling system that uses water as a secondary refrigerant. They are used for large, complex heating, ventilating, air conditioning, and refrigeration (HVACR) applications. Mild Steel Galvanized Iron Definition and Importance Types of Pipe Used

4. Pipe Fittings Elbows (90°, 45°) Tees Reducers Couplings / Unions Flanges Grooved Fittings Thread and weld able elbows Welding Coupling with Threads Coupling with Flanges Common Types Jointing Methods 1 2

5. Types of Valves Shut off: Butterfly, Ball, Gate Control: Modulating/ Motorized Check: Swing, Spring Loaded Balancing: Manual/ Automatic Strainers, Auto Air Vent, Flow Switch Valves Used in HVAC System Valves are essential mechanical devices that regulate, direct, or control the flow of fluids (gases, liquids, or slurries) by opening, closing, or obstructing passageways

6. A ball valve is a flow control device which uses a hollow, perforated, and pivoting ball to control fluid flowing through it. 1 2 A butterfly valve is a type of valve used to regulate or isolate the flow of a fluid (liquid, gas, or slurry) in a pipeline. It's characterized by a disc-shaped element that rotates within the valve body to control the flow Butterfly Valve Ball Valve Shut off Valve A gate valve is a linear motion valve used to start or stop the flow of fluid by raising or lowering a solid barrier, called a "gate," into the path of the fluid. It's designed for on-off service and is not suitable for regulating flow. When fully open, it offers minimal resistance to flow, and when closed, it provides a tight seal.  . 3 Gate Valve

7. Control Valve Motorized valves are typically used for on-off or two-position control (fully open or fully closed) . Motorized Valve modulating valves offer proportional control, allowing for precise regulation of flow between fully open and fully closed based on given signal Modulating Valve

8. Check Valve A swing check valve is a type of one-way valve that prevents backflow in pipelines by using a hinged disc that swings open with forward flow and closes against the seat to prevent reverse flow Swing Spring loaded check valves prevent reverse flow and ensure one flow direction. They have one single inlet and one single outlet that can only be used in the correct orientation for proper functionality. Spring Loaded Valves are essential mechanical devices that regulate, direct, or control the flow of fluids (gases, liquids, or slurries) by opening, closing, or obstructing passageways

9. Balancing Valve A balancing valve is a specialized valve designed to regulate flow rates and maintain proper pipeline system function. Balancing valves have excellent flow regulation characteristics; they ensure consistency by controlling and equalizing pressure levels in disparate areas throughout piping systems . A manual balancing valve is a type of valve used in fluid systems to regulate and balance flow rates. It requires manual adjustment, typically via a handwheel or lever, to fine-tune the flow to the desired level Manual An Automatic Balancing Valve (ABV) is a type of valve used in hydronic systems, like heating and cooling, that automatically adjusts to maintain a desired flow rate, even when pressure fluctuates. Automatic

10. Strainer Y-strainers are a type of strainer used in piping systems to remove unwanted solids from liquids, gases, or steam. They are named for their Y-shaped design and are crucial for protecting downstream equipment like pumps, meters, and control valves from damage caused by debris.  Y Strainer Fabricated Pot Strainers feature top removal of the screen. The screen is in the form of a basket, with a lifting handle, so that all particulate captured. Pot Strainer Strainers in piping systems are devices that remove unwanted solid particles, debris, and impurities from fluids, protecting downstream equipment and ensuring the system operates efficiently
