Basket filters & strainers will permit the straining & filtering of a wide variety of fluids, to retain solids of almost any size. All baskets are easily removable & cleanable. Basket strainer elements can be offered in single cylinder, double cylinder, multi cylinder & pleated design depending upon requirement of application. They are constructed of filter housing, filter element supported with perforated cage, positive sealing arrangement to avoid any bypass & choice of end connections. Operation Unfiltered liquid enters the basket housing and passes down through them. Solids are retained inside/ outside of basket depending upon design and are removed when the unit is serviced.They are available with insitu backwashing arrangement, wherein removal of baskets for cleaning is not required often. Basket filters & strainers are normally supplied with spring arrangement at the top of filter element. This will ensure any type of bypassing & confirm the position of basket, even in case of reverse flow. Fluid bypass around the basket is prevented by an optional O'-Ring seal between the basket rim and the housing inside diameter. 

A PTFE Lined Swing Check Valve is a type of non-return valve designed to allow fluid flow in one direction and prevent backflow, featuring an internal lining of PTFE (Polytetrafluoroethylene) for excellent chemical resistance. The swing check mechanism uses a hinged disc that swings open with forward flow and closes against a seat to block reverse flow.

A PTFE/PFA Lined Butterfly Valve is a high-performance valve engineered for corrosive and aggressive chemical applications, offering superior protection with an internal lining of PTFE (Polytetrafluoroethylene) or PFA (Perfluoroalkoxy alkane). These valves are widely used in industries where chemical resistance, purity, and reliability are critical.

A PTFE Lined Flush Bottom Valve is a specialized industrial valve designed for draining, sampling, or discharging fluids from the bottom of tanks, vessels, or pipelines, especially when handling corrosive, abrasive, or high-purity chemicals. These valves are lined internally with PTFE (Polytetrafluoroethylene) or other fluoropolymers to provide exceptional corrosion resistance and prevent product contamination.

A flame arrester functions by absorbing the heat from a flame front thus dropping the burning gas/air mixture below its auto-ignition temperature; consequently, the flame cannot survive. The heat is absorbed through channels (passages) designed into an element.

A PTFE Lined Plug Valve is a type of quarter-turn valve designed to control the flow of corrosive or aggressive chemicals. It features a metal body internally lined with PTFE (Polytetrafluoroethylene) or other fluoropolymers, providing excellent chemical resistance and low friction operation. The plug, also lined with PTFE, rotates inside the valve body to open or close the flow passage.
