Pneumatic Hook-Up
Type P327D Pneumatic Release
Block Installation
If several valves are installed at the same location, remote
release may be accomplished with the Type P327D
pneumatic release block which replaces the cable latch
block installed on the Type N550 valves.
To install the Type P327D, see Figure 4:
1. Close the Type N550 valve. Handle is parallel to
the pipe.
2. Remove the long end of the external spring from
under the latch block.
DO NOT REMOVE
SPRING FROM HANDLE.
3. Remove latch bolt(s). Older valves will have 2
bolts.
DISCARD CABLE LATCH BLOCK.
4. Use a 5/32-inch (4 mm) Allen head wrench to
screw 1/4-inch (6,4 mm) long bolt into bottom hole.
5. Tighten until bolt head seats firmly on body.
6. Place latch block on body with lower blind hole
over bolt in body.
7. Install 3/4-inch (19 mm) long bolt through
second hole and firmly tighten with 5/32-inch
(4 mm) Allen head wrench.
8. Refasten long end of spring under latch block by
ROTATING 180 DEGREES CLOCKWISE.
9. Attach the remote air source to the cylinder end
with appropriate supply tubing and valving. A
regulated air supply of
30 to 70 PSIG (2,1 to
4,8 bar)
to the Type P327D pneumatic release
cylinder is required for proper operation.
