Operating Pressure

200 to 750 psig (14 to 52 bar)

Proof Differential and Tolerance

For actuation pressures of 200-350 psig (14 - 24 bar), tolerance is ±10 psig (±0.7 bar),

60-70% is standard differential;

351-500 psig (24 - 34.5 bar), ±10 psig (±0.7 bar), 65-75% differential;

Differential = (release setpoint/actuation setpoint) X 100.

Release Tolerance setpoint on all devices (0.2 bar), ±30 psig.

Proof Pressure

600 psig (41 bar) for actuation pressure up to 400 psig (28 bar);

800 psig (55 bar) for higher actuation pressures

Burst Pressure

5000 psig (345 bar)
