Asco Numatics product story

Asco/Joucomatic Numatics valves feature a patented piston design that enables significantly faster opening and closing times, quieter operation and lower operating costs.
Asco/Joucomatic Numatics has launched a 33mm version of its highly successful type 353/800 Power Pulse valves.
Specifically designed for the dust collector market, the valves feature a patented piston design that enables significantly faster opening and closing times, quieter operation and lower operating costs.
Power Pulse valves form part of a comprehensive dust collector offering that includes valves with integral and remote pilots, tanks, manifolds and complete systems.
The patented piston design of the Power Pulse valves substantially reduces the stroke volume while still enabling high flow rates.
The reduced stroke volume cuts the amount of air to be exhausted, resulting in faster operation and enabling savings to be made in compressed air production.
A new bonnet design allows the air to expand inside the valve, lowering the noise at exhaust.
For applications where there is a possibility of dirt build-up blocking the silencer, an option is available to enable exhaust gasses to vent directly into the valve outlet port.
Power Pulse valves are very compact and the option of a remote pilot makes them even more attractive for applications where space is at a premium.
Remote pilots can be mounted individually or supplied in boxes, operating from two to twelve valves and having the benefits of a common inlet and exhaust.
Able to operate in harsh environments, the standard design can operate up to 85C which can be extended to 150C with the optional high-temperature Polyamide piston.
Coil options include high-quality F-class epoxy moulded coils and a range of waterproof and explosion-proof coils conforming to the ATEX directive 94/9/EC for use in potentially explosive atmospheres.
To enable easy installation, the valves can be supplied with a quick mount connection system eliminating time-consuming thread cutting and sealing to the blow-pipe, which is required when installing conventional dust pulse valves.
It also costs less and is more effective than compression-fitting methods.
