Overview
Features & Benefits:
- Primarily for use in vapor heating systems, but also may be used with liquids, air, and other noncombustible gases
- Stainless steel diaphragm also allows use with ammonia, oxygen, distilled water, and similar media
- Maximum surge pressure of 15 psi (103.4 kPa)
- All models have an adjustable subtractive differential
- Adjustments are made by screws on top of case
- Scaleplates are marked in English (psi) and metric (kPa) units
- Case has clear plastic cover so that pressure settings can be observed
- Hexagonal fitting with 1/4-18 NPT internal threads for direct mounting to the 50024585-001 Brass or 14206 Steel Steam Trap (siphon loop)
- Can also be surface mounted by screws through holes (knockouts) in back of case
- Ground screw terminal
