Safety Valves with metal seats will start to leak at 90% of set
pressure. A Spence Safety Valve equipped with a soft seat
seals on both the metal and soft seats (see illustration). As a
result, it will not begin to leak until system pressure reaches
95% of set pressure, minimizing system energy loss.
The o-rings in standard soft seat safety valves tend to blow out
during discharge. Spence Soft Seat Safety Valves utilize a flat
soft seat insert in the disc assembly of the valve that stays in
place during operation, thus providing hassle-free operation.
There are many troublesome applications where using a
Spence Soft Seat Safety Valve can reduce costly downtime
and repair costs. Consider a Spence Soft Seat Safety Valve
for:
● Operating very close to set pressure
● Heavy vibration
● Hard-to-hold fluids
● Occasional foreign particles
● Icing problems
● Pipe strain due to excessive discharge
