Plug Valves ? Lubricated Pressure Balanced

Econo Valves is one of the foremost quality manufacturers of a wide range of valves, having earned a reputation for trust and reliability. The company offers lubricated pressure balanced plug valves. Plug valves have a field proven performance in India and abroad for many years and even now are referred to as the only valves to offer drip tight sealing capability. These valves handle liquids, gases (both clean and dirty), aggressive and corrosive liquids and slurries and most importantly have performed well the test of time. Advantages: larger seating area compared to other valves; no bonnet cavity; no high projection yoke; no exposed thread to corrode; no under hanging body to waste vital space; no stem breakage; 100% shut off on services can be achieved by injecting sealant in open or close conditions (other valves offer this as secondary sealing feature knowing that one-day primary seats will fail – this is not a pressurised sealant system as used in plug valves); low pressure drop; intrinsic – fire safe since valve is metal seated; capacity to operate under any differential pressure since this has no bearing on valve operating torque; facility to ease valves from seat in case of difficulties in operation (this can happen in all types of valves but easing of seat may not be possible in other types); and the valves offer lower, predictable operating torque under wide differentials/working pressures than any other valve. Features: PTFE treatment; large seating area (protected); fire-safe graphite stem seal; emergency stem seals; lapped taper surfaces for precise sealing; external provision for plug sealant; fire-safe design; position indicator; and blow out proof stem. Benefits: smooth and consistent torque; freedom from regular maintenance; certainty of operation; assured sealing; certainty of sealing across the seats; online maintenance possible; increased overall reliability; indicates valve in open/close position; and safety to atmosphere.
