Model "SP" ASME safety valves are designed for applications where a compact size is required and high flow capacities are not needed.
For example, a 3 HP compressor may add 10 SCFM of air into the receiver at 125 PSI. The "SP" will flow 42 SCFM at 125 PSI set pressure, so it will be adequate for this system.
Resilient flourocarbon rubber pad insures valve is bubble-tight to within 10% of set pressure. 1/8" NPT and 1/4" NPT inlets available.
All brass construction with stainless steel spring. Stamped with "UV" and "NB" symbols. Available set pressure range 75 PSI to 250 PSI. Set pressure tolerance +3% of set pressure. 250°F max. temperature.
