Steam Trap

Steam Trap:


                    Steam traps are a type of automatic valve that filters out condensate (i.e. condensed steam) and non-condensable gases such as air without letting steam escape. In industry, steam is used regularly for heating or as a driving force for mechanical power. Steam traps are used in such applications to ensure that steam is not wasted.
steam trap - Self contained valve which automatically drains the condensate from a steam containing enclosure while remaining tight to live steam, or if necessary, allowing steam to flow at a controlled or adjusted rate. Most steam traps will also pass non-condensable gases while remaining tight to live steam.
Few famous brands are:spirax sarco,yarway and Tlv
 

Blow Down Valve


 Blow Down Valve(BDV)
                  
                              A valve or system of valves that, when activated, initiates a blowdown of a pipeline, plant, process or platform; similar to an emergency shutdown valve (ESDV) that shuts in a pipeline, the BDV opens a pipeline.
                       Hopkinsons Blowdown valves are commonly used to control the concentration of dissolved solids in the boiler water. The valves are designed and manufactured according to the requirements of the boiler and the industrial application. If a boiler makes use of more than one blowdown valves, then these two valves are often used in series to minimize erosion. Here, one valve acts as a sealing valve, and the other valve acts as a blowdown valve. The sealing valve is customarily opened first and closed last. To minimize the erosion on the disk faces and the seats, both of the valves are opened simultaneously and rapidly.

Safety Valve

Safety Valve:


                    A safety valve is a valve that acts as a fail-safe in a thermal-hydraulics plant. An example of safety valve is a pressure relief valve (PRV), which automatically releases a substance from a boiler,pressure vessel or other system, when the pressure or temperature exceeds preset limits.Pilot-operated relief valves are a specialized type of pressure safety valve.

Strainer

Strainer: 

                                       Line strainers protect your fluid handling system against the damage that can occur to valves, traps, and other equipment when foreign matter such as dirt, scale or welding particles travel through the pipeline. strainers are suitable for most general straining purposes on non-aggressive fluids. The strainer may be used on all types of pipelines to collect granulated foreign substances and contaminants collected. It can improve the clearance in the medium,and prolong the life of valves and other equipments.

Plug Valve


Plug Valve:
                          
                        Plug Valves are valves with cylindrical or conically tapered "plugs" which can be rotated inside the valve body to control flow through the valve. The plugs in plug valves have one or more hollow passageways going sideways through the plug, so that fluid can flow through the plug when the valve is open.Audco Plug valves are simple and often economical.

Ball Valve

Ball Valve:

                                A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball to control flow through it. It is open when the ball's hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle.The handle lies flat in alignment with the flow when open,and is perpendicular to it when closed, making for easy visual confirmation of the valve's status. Ball valves are durable, performing well after many cycles, and reliable, closing securely even after long periods of disuse. These qualities make them an excellent choice for shutoff and control applications.

Butterfly Valve

Butterfly Valve: 

                                      

                        Butterfly valves are quick opening valves that consist of a metal circular disc or vane with its pivot axes at right angles to the direction of flow in the pipe,which when rotate on a shaft, seals against seats in the valve body.The are normally used as throttling valves to control flow.Butterfly valves control the flow of gas or liquid by means of a disk, which turns on a diametrical axis inside a pipe or by two semicircular plates hinged on a common spindle,which permits flow in only one direction.These valves offer a rotary stem movement of 90 degrees or less,in a compact design.Unlike ball valves,butterfly valves do not have any pockets in which fluids may become trapped when the valve is closed.
