Type ACE95jr

9

10. Place the range spring (key 8) over the diaphragm 

retaining nut (key 13). Place the spring seat 

(key 5) onto the spring.

11. 

Place the spring case gasket (key 9) between the 

spring case (key 7) and the upper actuator case 

(key 33) before attaching the spring case to the 

upper actuator case. Attach the spring case to 

the upper actuator case using hex-head screws 

(key 32).

12. Place the upper actuator case (key 33) over the 

range spring (key 8) and lower actuator case 

(key 30).

13. 

Install hex-head screws (key 32) with lock washers 

(key 28) and nuts (key 31) into the upper and 

lower actuator cases (keys 33 and 30).

14. 

Tighten all hex-head screws (key 32) in a 

criss-cross pattern.

15. 

Thread the range spring adjusting screw (key 2) in 

about half-way.

16. Reinstall the valve according to the instructions in 

the Installation section.

17. Adjust the setpoint (refer to Adjustment section).
18. Thread the actuator cap (key 1) into place on top 

of the spring case (key 7).

Diaphragm/Actuator Sub-Assembly

1.  Place an O-ring (key 41) onto the cage (key 52) 

and the gasket (key 27) onto the body (key 18).

2. 

Place the lower actuator case (key 30) onto the 

body (key 18).

3. 

To attach the lower actuator case (key 30) to the 

body (key 18), install hex-head screws (key 55) 

with lock washers (key 54). Tighten all uniformly.

4.  Place an O-ring (key 14) into the groove of the 

diaphragm bolt (key 15).

5. 

Build the diaphragm sub-assembly with the 

diaphragm (key 11) and two diaphragm plates 

(keys 10 and 48). Fasten the plates together with 

the diaphragm bolt (key 15) and the diaphragm 

retaining nut (key 13). Apply Loctite

®

 #222 to the 

diaphragm bolt.

Note

In cases where the pressure range 

is positive, the upper diaphragm 

plate (key 10) is larger than the lower 

diaphragm plate (key 48). See Figure 6.

6.  If you are using a negative spring range, install 

the lower range spring (key 162) into the lower 

actuator case (key 30).

7.  Place the diaphragm sub-assembly into the 

lower actuator case (key 30) with the diaphragm 

retaining nut (key 13) on top. Take care not to 

install upside down.

8.  Align the holes of the diaphragm (key 11) to the 

lower actuator case (key 30).

9.  Place the diaphragm gasket (key 12) on top of the 

diaphragm (key 11).

Parts Ordering

Each Type ACE95jr Tank Blanketing valve is 

assigned a serial number which can be found on 

the nameplate on the main valve actuator. Refer 

to this number when contacting your local Sales 

Office for assistance or when ordering replacement 

parts. When ordering a replacement part, be sure to 

reference the key number or each needed part and 

include the complete 11-character part number from
