Victor by ESAB 0781-0527 SR 450 1-Stage Heavy Duty Welding Regulator

Brass adjusting screw with forged T-handle (VTS 700 only)
Delrin insert bushing for durability, easier adjusting
Die-forged brass sprying housing cap provides greater strength and durability
Stainless steel diaphragm gives accurate long lasting service
Stem type seat mechanism inlet pressure aides in sealing
Stainless ball in key for easy adjustment
Adjusting spring pretested for quality assurance
Die-forged brass body for extra strength
Precision machined nozzle for optimum flow control
Adjusting spring designed for precise preset
external self reseating relief valve - not designed to protect downstream equipment (no relief valve is needed on low pressure fuel gas models)
Sintered inlet filter - electroless nickel plated bronze
Regulators will deliver - at least the stated upper range and in some cases may exceed the stated upper range
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
Designed for medium to high capacity
Recommended for applications that require a constant delivery pressure over a range of decreasing inlet pressures
This precise two stage regulation provides superior operating characteristics for applications where change in delivery pressure would affect performance characteristics of work or test results
3000 psi maximum inlet pressure
4000 - 200 inlet to outlet gauge range
0.27 Cv flow coefficient
