Model “SP”

Model “SP” ASME safety valves are designed for applications where a compact size is required for high flow capacities. 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 fluorocarbon rubber pad ensures valve is bubble-tight to within 10% of set pressure. The valve is stamped with “UV” and “NB” symbols. Set pressure tolerance is +/-3%.

Construction: All brass with stainless steel springs
Max. Temperature: 250ºF

Model “SP”

Model “ST”

Model “ST” ASME safety valve is our standard safety valve for small air compressor systems and other related applications. While the size is compact, the flow capacities are high. Resilient rubber pad, offered in silicone or fluorocarbon, ensures valve is bubble-tight to within 10% of set pressure. The valve is stamped with “UV” and “NB” symbols. Set pressure tolerance is +/-3%.

Construction: All brass, zinc-plated music wire or stainless steel spring
Max. Temperature: 250ºF

Model “ST”

Model “SA”

Model “SA” ASME safety valves are designed for high temperature applications such as intercoolers and after-coolers, where a compact size is required. The valve is stamped with “UV” and “NB” symbols. Set pressure tolerance is +/-3%.

Construction: All brass, stainless steel spring and stainless steel ball seating on brass seat
Max. Temperature: 400ºF

Model “SA”

Model “SF”

Model “SF” ASME safety valves are designed for systems where large flow capacities are needed. Resilient pad ensures valve is bubble-tight to within 10% of set pressure. The valve is stamped with “UV” and “NB” symbols. Set pressure tolerance is +/- 3%.

Construction: All brass, zinc-plated music wire or stainless steel spring and a rubber seal, offered in silicone or fluorocarbon.
Max. Temperature: 200ºF
