When your job demands high-pressure control you can trust, the Victor SR 4G-346 Air Regulator delivers. Designed for the toughest industrial environments, this heavy-duty regulator is the go-to choice for professionals performing pressure vessel and dead-end testing. With a delivery range of 100 to 1500 PSIG, it provides the power and precision needed for high-stakes applications where standard regulators simply fall short.
Victor has built a reputation on quality, and the SR 4G-346 is no exception. The body and housing cap are machined from solid brass, ensuring the unit can take a beating in the shop or out in the field. Inside, a brass piston actuation system replaces the fragile diaphragms found in lighter-duty models. This piston design is critical for high-pressure service, offering superior resistance to wear and tear. Coupled with a PCTFE seat cartridge, this regulator is designed to hold pressure reliably and resist the deformation that causes leaks in lesser equipment.
Adjusting high pressure shouldn't be a struggle. The SR 4G-346 features a Delrin cap bushing that ensures the adjustment knob turns smoothly, allowing you to dial in the exact pressure you need without fighting the mechanism. The large 2.5-inch brass gauges are easy to read at a glance, keeping you informed of your tank and line pressure. For added peace of mind, the unit includes a sintered bronze inlet filter to keep dirt out of the seat assembly and an external adjustable relief valve to protect your equipment from over-pressurization.
This regulator comes ready to connect with a CGA 346 inlet, compatible with standard high-pressure air cylinders (up to 3000 PSIG). The outlet is outfitted with a 1/4" Swagelok connection and stainless steel tube fitting, providing a secure, leak-free attachment point for your testing lines. If you need a regulator that works as hard as you do, upgrade to the Victor SR 4G-346.
