Functional valves do one specific job: speed up a cylinder, prevent backflow, throttle a line, isolate a circuit, build an OR-logic from two pilots, or reduce pressure right where the actuator needs it. NorTrade distributes the full Norgren IMI functional-valve range — seventeen series across quick exhaust (S/511, T70), non-return / check (T55, T56, T50P, S/520), uni- and bi-directional flow regulators (M/800, T1000, T1100, T20), ball and shut-off valves (60, 6151 stainless, M/7300), excess-flow air fuse (T60), OR-logic shuttle (T65), pneumatic sensor (102GD) and inline pressure reducer (102GB).

Quick exhaust valves (T70, S/51x) shorten the return stroke of a cylinder by exhausting air at the cylinder itself rather than back through the directional valve. The bigger the cylinder and the longer the tubing run, the bigger the gain — substantially shortening the return time. Forward stroke is unaffected.
T55 (aluminium, VMQ-free) — general industry, G1/8 to G1/2, silicone-free for paint shops. T56 (brass, VMQ-free) — when a brass external is required, 1/8" or 1/4" ISO G/NPT. S/520 family — heavier duty, larger ports up to G1, brass body, high pressure. T50P — when you want the check valve inside the tubing, no separate fitting.
Uni-directional (T1000, M/800) meters in one direction and lets full flow pass in the other — usually for exhaust-side speed control. Bi-directional (T1100) meters in both directions — useful where you want symmetric extend/retract speeds, or where the cylinder is double-acting and you cannot rely on free-flow logic.
An air fuse (T60) is a safety device that automatically closes when downstream flow exceeds a threshold. Typical use case: protection against burst-hose whip on portable tools or compressed-air manifolds. Helps comply with workplace safety regulations. Auto-resets when the burst is repaired.
Choose the 6151 (stainless steel) when the brass 60 series would corrode — chemical processing, food and beverage, pharma, marine, wash-down areas, or where regulations require stainless wetted parts. Both are full bore, both are maintenance-free; the cost premium of stainless is justified only when the environment demands it.
The 102GD detects pressure changes in a pneumatic line and switches an output accordingly — effectively a pneumatic-only position sensor for cylinders. The right choice where adding electric sensors is impractical: all-pneumatic logic machines, or simple cost-down on small assemblies.
