Ksb – ECOLINE GTB 150-600

– Leak-free stem seal

– Primary sealing to atmosphere is provided by a multi-walled metal bellows welded to the stem and a graphite gasket between body and bonnet.
– Secondary sealing of the stem passage to atmosphere is provided by a minimum of five graphite packing rings plus lower gland section for added safety.

– Longer service life of valve and bellows

– Specially designed multi-ply stainless steel bellows offers excellent corrosion resistance and flexibility; designed to withstand 1.5 times the nominal valve pressure.
– Stellite hard-facing applied to the seating surfaces of the body and valve disc prevents the valve disc from seizing on the seat and reduces wear.

– Reliable leakage protection of body

– Gaskets are fitted above and below the end fitting of the bellows assembly and firmly compressed by a set of bolts and nuts. The lower gasket is confined by the body shoulder and the end fitting of the bellows to prevent excessive compression.
– Identical joint rings of bonnet seal and yoke seal prevent excessive compression.

– Ease of service without additional costs

– No costs for daily or frequent maintenance work during valve duty thanks to reliable bellows seal between the stem and the body.
– If required, a leakage monitoring hole can be provided in the gland packing area.
– The bolted bonnet and the design of the stem and bellows assembly enable straightforward dismantling in the event that defective internal components need to be replaced.

– Operating reliability

– Standard travel stop prevents excessive valve travel which could destroy the bellows or reduce the expected service life of the bellows.
– Available for all kinds of fluids
– Several material variants available for body and bellows to suit a variety of fluids and applications.
