Victor 0781-0532 SR450D-346 Professional Single Stage SR450-D High Capacity Regulator

Victor 0781-0532 SR450D-346 Professional Single Stage SR450-D High Capacity Regulator has been recommended for applications where slight delivery pressure increases (due to decreasing cylinder pressures) would not affect the performance characteristics of the work or test results. The SR450 regulators are designed for heavy duty applications and for larger cylinders. Delivery Range in PSIG is 5-125. Gauge range inlet is 4000 and the outlet is 200. CGA inlet connection is 346 and the outlet connection is 5/8 inch - 18 F LH. Maximum inlet pressure in PSIG is 3000 and the flow coefficient in Cv is 0.27. Brass adjusting screw with a forged T-handle and a Delrin insert bushing for durability and easier adjusting. Stainless steel diaphragm that gives accurate long lasting service and a stem-type seat mechanism inlet pressure that aides in sealing. There is a stainless steel ball in key for easy adjustment and an adjusting spring pretested for quality assurance. Die-forged brass body for extra strength and a precision machined nozzle for optimum flow control. Extra features include an external self reseating relief valve and a sintered inlet filter. This regulator will deliver at least the stated upper range an in some cases may exceed the stated upper range.
