Ball Valves Floating & Trunnion mounted resilient
& Metal seated. / Cryogenic Ball Valves
Ball valves / Resilient Seat Applications :
Resilient-seated ball valves have good sealing performances
and a variety of choices for the materials depending on the working conditions.
Resilient-seated Ball valves are widely used for pure medium,
such as water, LNG, coal gas, natural gas, oil, nitric acid.
Resilient Seat Parameters :
Nominal diameter : 1/2" ~ 48" (DN15 ~ DN1200)
Pressure class : Class150 ~ Class2500 (PN16 ~ PN420)
Working Temperature : -196˚C ~ 260˚C
Structure : floating ball / trunnion mountedBody
Type : two-piece / three-pieceMaterial forming
process : cast / forged
Drive type : manual, worm gear, electric, pneumatic, hydraulic
Ball valves / Metal Seat
Applications :
Metal seated ball valves are suitable for cryogenic, high temperature, high pressure, abrasive and corrosive working conditions. It is an ideal equipment to shut off some special medium, such as the solid and gas mixed medium, solid and liquid mixed medium, high-viscosity medium, high-fiber medium, high temperature steam. It is widely used in the coal chemical, petrochemical, papermaking, poly-silicon industries and power stations.
