SVB Safety Valves

The SVB Safety Valves are used for over-pressure protection on unfired pressure vessels in saturated steam systems. Valves are 100% factory tested and made in the USA.

How It Works

In the event steam pressure increases to the set point, the safety valve will “pop open” discharging steam faster than it can be produced; allowing system pressure to return to safe levels at which point the valve will close.

Features

  • Stainless Steel springs
  • Teflon®-PFA seat resists corrosive boiler chemicals
  • Two control rings for maximum performance and adjustability
  • Tapped body drain allows piping of condensate away
    from valve to protect the internals from fouling
