OPERATION AND MAINTENANCE INSTRUCTIONS

514 SERIES MULTI-PORT BALL VALVES

HIGH CYCLE TYPE

2

 

Thank you for purchasing an Inline Industries 514 Series Multi-Port Ball Valve. This product has been constructed for maximum performance and system design flexibility. The 514 can be used for manual operation with a standard lockout device or easily adapted for electric or pneumatic automation. Our unique dual pattern ISO 5211 Direct Mount actuation system enhances actuator performance, improves safety and eliminates the need for costly brackets. Available in 3- and 4-way L or T flow patterns, with Schedule 40 threaded end connections and full or standard port construction, the 514 product line offers a number of solutions for your fluid processing needs.

 

Installation and Operation

Always install your valve according to accepted industry standards and practices and operate only within stated pressure, temperature and fluid media limits. Do not open or disassemble valve unless you intend to replace resilient seat and gasket materials. Repair kits are available from your local Inline representative or call 1-800-568-8998.

Your 514 is available lever operated with our standard lockout device and incorporates an integrally cast dual pattern ISO 5211 mounting pad for electric or pneumatic actuation. Product specification sheets and technical drawings are available for dimensional information required for proper installation and automation.

Maintenance

Resilient seated valve products may wear over time resulting in loosening at component boundaries. If leakage is detected, tighten according to the steps and torque values outlined below. If tightening does not correct the problem, it is time to replace your seats and seals.

 

Repair

Remove and Clean Valve

A.    If valve is in line, make sure system is purged and line, ball and cavity pressure is released before removing from piping system.

B.    Remove all add-on components such as actuators and set aside.

C.    Disassemble valve. Remove old seats and seals and discard them. Clean and dry metal components in preparation for reassembly.

 

Install Repair Kit and Reassemble Valve

Arrange cleaned valve parts on workbench. Position body with the single large bore hole facing up.

 

A.    Stem Assembly

 

1.     Place thrust washer on stem sliding over threaded end and seating on shoulder at base.

2.     Place Viton o-ring on stem sliding over threaded end and seating into groove notched at mid-point of stem.

3.     Insert stem into body cavity through side, threaded end first, and glide through the hole in the top of the body until seated.

4.     While holding stem in place, slide stem packing set over threaded end. Stem packing should be stacked with mating concave/convex sides facing each other. Slide over stem, concave piece first, until seated.

5.     Place stem packing follower bushing over threaded end of the stem and lower over stem packing.

6.     Position two spring (Belleville) washers with concave sides facing each other and lower set over stem bringing them to rest upon stem packing bushing.

1.     Thread stem nut down stem and hand tighten until stem and packing assembly are properly seated, aligned and in a fixed position. Tighten stem nut to the minimum torque specified in Table 1 and rotate slightly more until stem nut flats are perpendicular to stem flats. This will allow you to slide the lock washer down stem and into position over stem nut. (Please note: torque should not exceed maximum indicated in Table 1.) Thread second stem nut down over stem until resting on lock washer to keep stem assembly locked in place for further valve assembly and adjustments.

7.      

 

B.    End Caps/Ball (3-Way Configuration)

1.     Your 3-Way valve has three end caps, two small end caps and one large end cap (with a larger sized gasket). Place new seats, curved side up, in all three end caps. Lower the remaining seat into the body cavity, again with curved side up, until it fits securely into the seat retainer in back of body.

2.     Make sure seat is properly positioned. Orient the axis of the key at base of stem vertically so as to facilitate ball entry. Position the orifices on the ball to match the pattern stamped into the top of the stem. Carefully lower the ball into the body cavity top end first, gliding the ball key way over the stem key until cradled on the exposed seat. Please note that the 514 has a specially mounted retaining pin fixed perpendicular to the key way. The mating slot on the top of the ball must engage this pin when sliding over stem key for proper valve function.

3.     Select the large end cap.

4.     Gently slide the large gasket over the threaded end of the large end cap until coming to rest on the shoulder.

5.     Invert and gently insert the large end cap into large bore hole (facing upward) and thread into place until it rests against gasket. Ball should now be loosely secure.

6.     Turn valve body upright and inspect to see that the stem is straight and ball orifice is aligned with end cap bore hole. Use of a cylindrical dowel to properly align the axis of the ball with the end cap is highly recommended. Continue hand tightening until proper alignment is secured. Once positioned, tighten large end cap to the torque specified in Table 2.

7.     Repeat Steps 3-5 above for the two small end caps.

8.     Once small end caps are on and proper alignment is achieved, alternately tighten each small end cap one quarter turn with a torque wrench until reaching the torque specified in Table 2. This should ensure proper seating and alignment.

 

 

C. Final Assembly and Test

1.     Your 514 ball valve is now ready for final assembly, adjustment and testing. Remove top stem nut. Some models have a separate stop plate for handle positioning. If available, place stop plate over stem. Next, slide handle over stem in the orientation desired for clearance of proximate piping or as an indication of flow. (Eight positions are possible.) Hand tighten stem nut until handle is fixed in place. Secure with wrench.

2.     Submit valve to qualified valve test facility for pressure test.

 

Your repaired 514 ball valve is now ready for installation and service.

 

Inline Industries makes a number of other fluid processing valves which complement this offering. Please consult your local Inline representative for more information about our products or call 1-800-568-8998 for more details. Thank you for purchasing an Inline product.
