Piston Valves


YAKACIK piston valves can be used to control the flow of almost all kinds of fluids. YAKACIK VALF offers the optimum solutions. Valve
body material may be cast iron, ductile iron, cast steel and stainless steel with appropriate sealing rings.
 

Piston Valves have two important components: fine ground cylindrical
piston made of stainless steel and elastic valve rings. Suitable ring materials are
used for almost all kinds of fluids. Elastic upper lower rings compress the
pistob with the required tightness. Thrust is provided by tightening the bonnet
nuts. It is transmitted from upper ring to lower ring via lantern bushing. Axial
thrust is converted to radial pressure by compressing the elastic rings. The
compressed rings enable an outstanding leaktightness. the lower ring is leakproof
across the ports, the upper ring is leakproof to atmosphere. At fully open or fully
closed position, since there is no contact between the cylindrical piston surface
and the fluid; abrasion does not take place
