• Manufactured in accordance with ASME code Sec. VIII
• NB (National Board of Boiler and Pressure Vessel Inspectors) certified capacities for air, steam, water
• Pressure range from 15 psig to 6000 psig (1 barg to 414 barg)
• With TÜV type test approval
• Materials acc. to ASME
• Upon request fulfillment of NACE MR 0175 requirement available
• Sizes from 1D2 to 8T10
• Full nozzle type with single nozzle ring

Features and Benefits

1) Positive lift-stop at full capacity
2) One-trim-design, advantage e. g. a 2-phase flow Optimized disc bearing for high seat-tightness
3) High discharge coefficients for liquid service at 10% overpressure due to optimized flowgeometry and high position full nozzle seat
4) Easy maintenance because of designfeatures, e.g. one-part spindle, disc retainer
5) Dismanteling of bonnet for lapping of seat and disc without change of the set-pressure
6) Bellow in safe location, because outside the flowpath
7) Nozzle-ring in low position, e.g.outside the flowpath. Adjusting of ring not required
