Ross 2773B6085 Lockout Solenoid Valve

Overview

The Ross 2773B6085 is a piloted solenoid valve from the 27 Series, combining manual lockout (L-O-X®) control with soft-start EEZ-ON® functionality. This valve is designed to allow gradual buildup of downstream air pressure before opening the line to full air flow, which allows cylinders or other work elements to move slowly and more safely into their normal working positions before full line pressure buildup is applied. The Soft-Start EEZ-ON® valve provides gradual reapplication of pneumatic energy to prevent rapid equipment movement at startup.

Key Features

Manual L-O-X® Lockout Control: Each manual L-O-X® valve is equipped with a lockout function that immediately exhausts all downstream air into the atmosphere.
Soft-Start EEZ-ON® Operation: The time required for full pressure buildup is adjustable.
Energy Isolation Device: These products are defined as energy isolation devices, NOT AS EMERGENCY STOP DEVICES.
2/2 or 3/2 Configuration: EEZ-ON® valves are available as either 2/2 (2-port, 2-position) or 3/2 (3-port, 2-position) valves.
Low-Friction Spool Design: The controlling spool of the valve employs seals made of very low-friction material, which enables the L-O-X® spool to shift smoothly and easily even after being on standby for a long period of time.
