Strainers are essential part of pipe line components. Strainers are used for entrapping waste and solid impurities, in charged or pressurized lines, to avoid clogging of lines or damaging down line equipment.Sarker valves manufacture strainers in Cast Iron, Carbon Steel Fabricated. Y Type strainers ban be installed in Horizontal or Vertical configuration of pipe line. T Type Strainers acan be Installe similar to Y type in Vertical and Horizontal Configuration of pipe line. Pot Type or Basket Type can be installed only Horizontally Type of Strainers: Basket Type/Pot Type/’Y’ Type.Operation: Pipe Line Pressure.

    Sluice Cates are used for controlling flow of water, slurry, sewage etc. These gates are manufactured at our works in three designs Wall Mounted, Thimble Mounted or the open Channel Gates or gates can be manufactured to suit customer specific requirement also. Manufacturing conforms to various Indian or international standards. We at our works, have unique advantage of having our own foundry; dependence on outside source is negated.Type of Sluice Gates: Open Channel/Wall Mounted/Thimble Mounted.Operation: Manual/Gear Operated /Motorized.

A Globe Valve is a type of valve used for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body. Globe Valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle. This has an opening that forms a seat onto which a movableplug can be screwed in to close (or shut) the valve. The plug is also called a disc. In globe valves, the plug is connected to a stem which is operated by screw action using a handwheel in manual valves. Typically, automated globe valves use smooth stems rather than threaded and are opened and closed by an actuator assembly. The most common use of a globe valve is as a water tap. It is also used widely in industrial applications for flow control. Type of Valves: OS&Y rising Spindle.Operation: Manual, Gear Operated, or Motorized.Range Cast Iron & Cats Steel Valve Range: 50 MM NB to 300 mm NBForged & Bronze Valve Range: 15 mm NB to 50 mm NB

Gate Valves are by far the most widely used in industrial piping. That's because most valves are needed as stop valves - to fully shut off or fully turn on flow - the only job for which gate valves are recommended.Gate Valves are inherently suited for wide-open service. Flow moves in a straight line, and practically without resistance when disc/wedge is fully raised.The seating is perpendicular or at a right angle to the line of flow and meets it head on. That's one reason why Gate Valves are impractical for throttling service and for too frequent operation.The difference between Sluice Valves and Gate Valve is that the Gate Valves are generally used for water or water like fluids, while aSluice Valve is recommended for Slurries.Type of Valves: Non Rising Spindle and OS&Y Rising Spindle.Operation: Manual, Gear Operated, or Motorized.Cast Iron Valves Range: 50mm NB to 1200 mm NB, Cast Steel Valves Range: 50 mm NB to 300 mm NBForged & Bronze Valves Range: 15 mm NB to 50 mm NB  

Foot Valves are usually installed and positioned at the lowest point of the intake suction pipe of the pump, below the water level, and often near the bottom of lakes, rivers storage tanks and pits. Primarily, valve stops draining out of the water from the suction line of the pump, when the pump is stopped. Strainer of the valve does not allow foreign material or large objects from entering the suction, thereby damaging the pumps.Type of Valves: Lift Disc Type.Operation: Lift Check.Range: 50 mm NB to 200 mm NB

It is a valve mechanism used for avoiding overflow of water in large storage tanks. Valve is installed on the intake water line of the tank. Operation simple when the tank is full, ball is at the highest point and it closes the valve, when water level of tank falls below a certain point ball drops down and the valve opens and the water starts filling the tank. Type of Valves: Foot Valve.Operation: Autpmatic.

The Check Valve is an automatic shut-off valve. Under pressure and flow, the closure mechanism opens allowing the media to flow freely. When the flow and pressure stops, the closure mechanism returns automatically to the closed position, preventing the media from returning upstream. The most common installation is at the pump. ACheck Valve may be installed on the suction side of the pump to maintain the pump's prime in the event of a pump shutdown. A check valve will be used commonly on the discharge of the pump to prevent backflow from the downstream system, when the pump shuts off. Check Valves are used to prevent contaminated media in branches from flowing back into the main trunk line. The most common example is the use of backflow-prevention devices installed on any connection to a city water main. The backflow prevention device, a special form of check valve, prevents possibly contaminated water at a facility from flowing into the city water system when there is a sudden loss of water pressure in the main utility line. There are several other applications for check valves, but the purpose is always the same. While, there are several design of check valve, we manufacture Sawing Check Valve, Lift Check Valve, Dual Plate Check Valve & Multi Door Check Valve. Type of Valves: Check Valve.Operation: Swing Check/Dual Plate.Cast Iron Valve Range: 50 mm NB to 1200 mm NB Cast Steel Valve Range: 50 MM NB to 300 mm NB** Multidoor Valves are also available **  

A Butterfly Valve is a flow control device that incorporates a rotational disk to control the flowing media in a process. The disk is always in the passageway, but because it is relatively thin, it offers little resistance to flow.Early use of Butterfly Valves focused on water applications, but new designs and component materials have allowed them to be utilized in growing industrial fluid applications. Presently, butterfly valves can be found in almost every chemical plant handling a variety of diverse fluids.The Butterfly Valves can be used for on-off service or modulating service. Actuation is typically achieved either manually (handle, wrench, gear operator) or through an external power source to cycle the valve automatically. Type of Valves: Flanged & Wafer Type.Operation: Manual, Gear Operated or Motorized.

These valves are primarily used to remove air from Pipe Line when initially they are charged with water or fluids. It also helps in removing any trapped air during the operations.   When pipe lines are discharged with water or fluids it release air in the pipe line for quicker discharge of fluid to empty the line.   Type of Valves: Single Ball/Double Ball/Kinetic. Operation: Automatic.
