• Models 913 and 919 available with Tri-clover adapter inlet (see page 5 for applicable parts and materials information).

NOTES

1. ASME standard valves for air, steam and hot water above 140°F (60°C) must have lift lever.

2. Requires variations listed below for adjustable relief pressure settings:

Variation 10: 60 – 125 psig (4.1 – 8.6 barg)

Variation 11: 126 – 175 psig (8.7 – 12 barg)

Variation 12: 176 – 250 psig (12.1 -17.2 barg)

3. For vacuum service: Temperature range is -30°/250°F (-34°/121°C).

4. Maximum back pressure 50 psig (3.4 barg).

5. Back pressure increases set pressure on a one to one basis, and reduces capacity. Back pressure in excess of 10% of set pressure is not recommended.

6. Same options available as Models 910, 911, 916, 917, 920, 921, and 927.

NOTES

1. See specifications table for pressure and temperature limitations.

2. Liquid conversion factors to determine liquid capacity at other than 10% accumulation, multiply by the following:

1.022 = 15% accumulation

1.045 = 20% accumulation

1.066 = 25% accumulation
