EZ Series Pneumatic Lock-Out Valve

Brand: Wilkerson Corporation
Request Information
Favorite

The EZ series meets all the same standards as the LV series with the added feature of a soft start when opened. There are still 2 detented positions for the handle (push close, pull to open), but when pulled open, an adjustable needle valve controls the rate of pressure build-up. This can protect equipment during start up after maintenance.
Features
  • Combines lockout and soft-start functions in a single unit
  • Used in systems for compliance with OSHA standard 29 CFR part 1910
  • 3/8 Inch to 1-1/4 inch pipe sizes
  • Cv’s from 3.7 To 13.7
  • 3/4 and 1-1/4 inch: exhaust ports available
  • Exhaust port threaded for installation of silencer or line for remote exhausting
  • Inline or surface mountable
  • Yellow cast aluminum body with red handle. Blue dot on body indicates EZ Series valve
  • Fluorcarbon slipper seals for easy shifting, even after long periods of inactivity

EZ valves are installed in pneumatic drop legs, or individual pneumatic control lines (see Figure 1). In accordance with OSHA procedures, EZ valves are used during maintenance and service procedures of pneumatically (air) operated equipment. Prior to servicing, the red handle is pressed inward, blocking pressure and relieving all downstream air pressure. A padlock is installed through the locking hasp, preventing accidental actuation during the maintenance procedure. Following maintenance, the padlock is removed and the red handle is pulled outward, gradually returning air pressure to the system. (For complete Lockout / Tagout procedures, consult OSHA Standard 29 CFR Part 1910 in U.S. Federal Register/Vol. 54 No. 169, Friday, September 1, 1989 / Page 36644.)
