27 Series Lockout L-O-X® Valves with Soft Start EEZ-ON® Y2783B2055
- Dirt tolerant, wear compensating for quick response and high flow capacity
- Operated like the manual lockout L-O-X® valve, the position of the blue handle indicates instantaneous full flow pressurizing or exhausting capability
- Allows the air supply to be turned on or off by remote electrical control when valve is not in the lockout position
- An adjustable restriction within the EEZ-ON®valve determines the rate of downstream pressure buildup, and consequently the time delay for the full opening of the EEZ-ON® valve
- Full size exhaust ports (equal to or larger than supply) provide rapid exhaust of downstream air and are threaded for silencers or remote exhaust lines
- Design only allows the valve to be lockable in the OFF position
- Fluorocarbon slipper seals for easy shifting, even after long periods of inactivity
