Transportation of petrochemical and chemical products as well as liquefied gas products (LPG and others) requires the highest standard of valve performance, particularly in the transportation of flammable or hazardous fluids and gases by liquid and gas marine tankers. NBS's UNIFLOW has been used extensively in marine tankers carrying refined oil products, chemicals and gases.

Wafer Type

Double Flanged Type

Complete Bi-directional Sealing. Double Seat eliminates deforming or damaging under high differential pressure and high fluid velocity.

The Disc moves entirely away from the seat at all points in the very few degrees. This assures a long seat life.

TA-LUFT Approved No Maintenance is Necessary

Seat replacement can be done very easily and quickly without disassembling the shaft and disc.

It is a safety mechanism that can lock the valve fully closed or fully open positions.

Easy Maintenance. Its construction prevents contamination by rust, seawater etc and assures trouble-free operation.
