S400 high pressure cylinder regulator is particularly suited for put vessels under pressure, leak detection and purge of pipe work. A cylinder connector is necessary to connect it to the cylinder valve.

Key advantages

Decompresses the downstream regulation system by turning the handwheel counter-clockwise
Accurate pressure control for reliable service
Connection available for relief valve
Panel mouting possible due to the rear threads
