ASCO™ Dust Collector Valves
A pulse valve is judged by what happens in a few milliseconds: how fast it opens, how much air it dumps, and how completely it closes again. Get that wrong and you pay for it twice — in compressed air and in filter life.
Sizing a valve? Estimate flow, pressure drop or Cv/Kv with our free calculator.
Open the Flow Calculator →Reverse-jet cleaning works by shock: a very short, very high blast of compressed air snaps the filter bag and releases the dust cake. The valve is the entire mechanism of that shock, so the specification that matters is not flow at steady state but peak pressure delivered in the first milliseconds. A slow valve wastes air on a pulse that never develops enough force, and the cake stays put.
That is why the line is built in layers. The 353 is the pulse valve itself, from 3/4" to 3", with integral or remote pilot and a Quick Mount Clamp that removes thread cutting from the install. The 110 pilot box and the 257 command it remotely, keeping the electricals off the collector and, with built-in heaters, working at −40 °C. And the 355B and 357 tank systems take it further: the valves live immersed inside the header tank, which shortens the air path and puts up to 18 valves on one manifold.

353
353 (8353) Pulse Solenoid Valve
The core ASCO pulse valve: a solenoid pilot-operated diaphragm valve built for extremely fast pulsing in reverse-jet dust collectors, so filters clean better on less compressed air. Its patented Quick Mount Clamp connection removes thread cutting from the install.

- Cv 10 – 140
- Global Ex approvals
357
357 Tank System
Steel immersion tank system with welded end covers for high-capacity filter cleaning, with integral operators and service connections for filter regulator, pressure gauge, safety valve and drain.
- Immersion valves
- IP65
- PED 2014/68/EU
110
110 Pilot Valve Box
Compact pilot box holding two to twelve direct-operated pilot valves, purpose-built to command Series 353 pulse valves remotely. Seats are integrated into the base plate, and it can carry heating elements for cold ambients.
- 2 – 12 stations
- To −40 °C
- IP65 · ATEX 2-22
257
257 Pilot Solenoid Valves
General-purpose and panel-mount pilot valves used to command large dust-collector pulse valves. Direct acting, normally closed, compact brass or plastic bodies, and zero minimum operating pressure.
- Zero min. pressure
- Cv 0.1 – 0.5
- UL · CSA
355B
355B Tank System
High-flow header tank built from an aluminium profile with end covers, carrying fully immersed pulse valves — up to 18 per tank, in several pitch distances, with quick-mount, push-in, hose or threaded blow-pipe connections.
- Up to 18 valves
- CR diaphragm
- PED 2014/68/EU
