Valves & Filters
SIGMA valves & filters can be relied upon to require minimum maintenance & to provide maximum reliability. These valves & filters provide the relatively easy on-off function to control flow & pressure relief. All wetted parts of valves & filters are made of borosilicate glass 3.3 & PTFE, which ensures maximum resistance to corrosion. The complete valve consists of Glass Valve Body, PTFE Bellow with nut, Bakelite Valve Bonnet with MS Spindle etc. Different types of valves like Line valve, Drain valve, Bottom outlet valve, Vent valve, Adjustable overflow valve, Non-return valve (flap type), Non-return valve (ball type), Pressure relief valve, Sampling valves are available.
Pipeline filters are recommended to remove impurities from gas & liquid streams in glass pipelines. The assembly is designed such that the filter can be easily removed for cleaning or replacement.
