Hi-B³

 

 

 

This ONIS Hi-B³ (Interlock Double Barrier Bleed & Blind) is a combination of an
ONIS Line Blind and one or two ball valves. It offers many benefits such as:

  • Reduced flange to flange dimensionn as ball valve is part of the ONIS
  • Dead chamber is minimized, the product loss during operation is lower
  • ONIS Hi-B³ uses less spiralwound gaskets when installed
  • Mechanical safety interlock between the Line Blind and the valves prevents any operation of the Line Blind if the valves remain open
  • Drain ports are included

There is two models of ONIS Hi-B³ :
> Model 1V1: Single block and bleed Line Blind system, with one ball valve.
> Model 2V1: Double block and bleed Line Blind system, with two ball valves.

Like all our products, the Hi-B³ is available in special steels (carbon steel, stainless steel, Ni-Alloys, duplex, inconel,…) for a wide range of temperatures, pressures and mediums and also available in fire safe design with graphite gaskets.
