Line voltage pressure controllers that provide operating control or automatic limit protection for pressure systems of up to 4 psi (27.6 kPa). All models have Microswitch snap switches to open or close a circuit on a pressure rise.

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.
