General Air Products manufactures ASME safety/shut-off valves that are bubble-tight to within 10 percent of set pressure. The valves feature set pressure ranges of 75-250 psig, 25-350 psig, 50-350 psig, 50-250 psig, and 25-300 psig. The majority of the shut-off valves are design for high temperature applications or system where large flow capacities are required.

Watts Water Technologies manufactures electric motor valves that feature bubble-tight shutoff, and are used in commercial HVAC zone control and light industrial applications. Theses shut-off type valves feature bronze body construction, a vented stainless steel ball, standard position indicator, and adjustable packing. The valves feature a pressure rating of 400 psi or 600 psi.

Plastic Engineered Products distributes automatic miniature shut-off valves for pressure applications up to 10 psi, and for use in low pressure and drain applications.

Emerson Process Management produces a 30 series shut-off valve, metal bellows shut-off valves, and metal diaphragm shut-off valves. The 30 series shut-off valves are for high pressure, high flow applications up to 10,000 psig. The valves are for use in GSE support pressure panels, instrumentation pressure panels and manifolds, R&D laboratories, and gas analysis sampling systems. The metal bellows shut-off valves feature a maximum operating pressure of 580 psig.

Enerpac distributes needle valves that can also be used as shut-off valves for temporary load holding. These valves feature a 3/8" thread and operating pressure of 0-10,000 psi.

Mahan Oven & Engineering distributes solenoid and safety shut-off valves produced by a number of leading manufacturers.
