Catalog 3900 - Pnuematic Couplings
E-z-mate Series are exhaust type quick couplers that are
designed to safely relieve air pressure prior to disconnection.
When the locking sleeve is moved to shut off air flow, it
automatically vents downstream allowing for disconnection at
zero pressure and eliminating the risk of “hose whip”.
Features:
•
Self- locking valve sleeve protects against accidental
disconnection
•
Push-to-connect operation
•
Meets ISO 4414 requirements for a controlled pressure
release system
Applications include:
•
Pneumatic tools
•
Drop-down air lines
Operation
Parker E-z-mate couplings combine push-to-connect, exhaust-
style action with a self-locking valve sleeve to guard against
accidental disconnection. Simply follow the direction of the
On-Off arrow stamped on the valve sleeve. It’s that easy.
To connect, push the nipple into the coupler. The black locking
sleeve automatically slides forward securely locking the nipple
in place. No air is allowed to flow through the coupling at this
point. The valve sleeve is then rotated clockwise (when viewed
from the coupler port end) to open flow and automatically
engage the sleeve-lock mechanism.
To disconnect, rotate the valve sleeve counter clockwise
(
when viewed from the coupler end). The flow of air through
the coupling will be shut off and all downstream air is vented
to the atmosphere. The locking sleeve may now be retracted
and the nipple removed. Lubricate sleeve as part of periodic
maintenance to coupler.
