DescriptionThe Pilot Valve Assemblies have been designed for remote actuation of ASCO’s Main Pulse Valves. The installer friendly layout, prewired solenoids are protected by a castaluminum watertight and corrosion resistant enclosure. Three sizes are available for up to a group of 12 valves with optional anti-frost heater. All ASCO’s pilot valves andenclosures offer long life and dependability to produce quality controls for today’s technically advanced dust collector system. For hazardous locations an explosion-proof model is available.

2 WAY HIGH FLOW (MAIN PULSE) VALVES

DescriptionSeries 8353 die cast aluminum, diaphragm operated valvesare specially designed for reverse jet type dust collectors.High flow, long life and fast opening combine to produce asuperior design for dust collector systems.OperationWhen the pilot valve is opened, air bleeds from the top ofthe diaphragm through the pilot valve orifice, opening themain valves. When the pilot valve is closed, air is trappedabove the main diaphragm closing the valve. Selection ofproper pilot valve orifice is important.

DescriptionASCO S-Series pressure switches consist of a switch unit and a trans-ducer unit. They can be ordered separately for customer stockingand/or field assembly or as a complete factory assembled unit.

are provided. The first method will automatically stop the sequence and reset theController to the first valve position whenever AC power is removed and thenreconnected. The second method is by a remote control contact connected to theterminals provided. When the remote contact is opened, the sequence stops. When theremote contact is reclosed, the sequence continues from the previous position.SpecificationsInput Voltage Range: 102 to 132 volts, 60 Hz.

Input Fuse: 3 amp, 125 volt, type AGC.

Pulse Duration Range of Adjustability: 20 to 200 milliseconds.

Number of Sequenced Steps: 2 through 10, adjustable in field, (factory set at 10).

Temperature Range:Operating: -10˚F to +130˚F (-23˚C to 54˚C)Storage: -20˚F to +150˚F (-29˚C to 66˚C)

Repetitive Accuracy on Time Sequences: ±5%

Current Ratings per Sequence Step:Maximum Inrush Current: 7.5 amps at 120 60 Hz. Maximum Continuous Current: 2.0 amps at 120 60 Hz.(NOTE: Solid-state elements require that minimum continuous current per sequencestep must not be less than 0.050 amperes. Consult factory for special ratingrequirements including operation below 0.050 amperes).

Dimensions, open type: 9” high x 7” wide x 5” deep.

Mounting: Four 3/4” long stand-offs are supplied for mounting within enclosure.

SPECIFICATIONS ADJUSTABLE DEADBAND TRANSDUCER UNITS

DescriptionThe ASCO Sequential Controller has been designed to operate theASCO pilot valves used on dust collector equipment. Light emittingdiodes (LED’s) provide visual indication of which pilot valve isbeing energized as well as “Power On” indication. The number ofsequenced steps is adjustable from 2 through 10. Method of OperationControls are provided to adjust the length of time between valvesbeing energized (Pulse Frequency) and the length of time that thevalve is energized (Pulse Duration). Silicon semiconductor components control all timing and logic functions.Two independent methods of starting and stopping the Controller

Switch S-Series pressure switch units incorporate the unique ASCO TRI-POINT alternating fulcrum balance plate to control the operation of one or more electrical snapaction switches. The electrical snap action switch together with the adjusting mechanism isa fully tested, self-contained, separate subassembly.Transducer Transducer unit incorporates a diaphragm/piston type pressure sensor, andis also a fully-tested, self-contained, separate subassembly.Operation When pressure is applied to the transducer it is converted into movement ofthe piston. This piston movement is then used to control the operation of the electricalsnap action switch in the switch unit.

Features• Visual adjustment scales in psi and bars.• External adjusting nuts.• Separate electrical, pressure and adjusting chambers.• 1/4 ” NPT connection
