A rugged, single-stage regulator engineered for extremely high gas flow at low inlet pressures. The Model 3590 uses a stainless-steel bar-stock body and stainless-steel diaphragm for long service life and low leakage, plus a one-piece encapsulated seat with an internal filter to protect the PTFE (Teflon®) seat. It’s rear-panel mountable and offers generous porting to suit pipeline, manifold, bulk supply, and low-pressure cylinder setups handling atmospheric or mildly corrosive gases.
Ultra-high flow performance for pipeline, manifold, and bulk systems
Stainless steel bar-stock body & bonnet for durability
Stainless steel diaphragm for corrosion resistance and tight shutoff
Encapsulated seat with internal filter to keep particles off the PTFE seat
2" stainless steel, dual-scale gauge (psi/bar) for clear readings
Ergonomic ABS adjustment knob for precise control
Rear-panel mountable design
Eight body ports: (2) 1/2" NPT and (6) 1/4" NPT for flexible inlet/outlet and gauge locations
Primary connections: 1/2" NPT(F) inlet and outlet
Auxiliary HP gauge port enables use in low-pressure cylinder applications
High-flow distribution from pipelines and manifolds
Bulk gas supply regulation
Low-pressure cylinder service (via auxiliary HP gauge port)
Suitable for atmospheric or mildly corrosive gases
