Sizes =BC=94=96 4=94

Thank you for = purchasing=20 Inline Industries=92 304F Series 3-Piece Ball Valve. This product has been = constructed for=20 maximum performance and system design flexibility. This valve can be used for = manual=20 operation with a standard lockout device or easily adapted for electric = or=20 pneumatic automation. Our = unique=20 dual pattern ISO 5211 Direct Mount actuation system enhances actuator=20 performance, improves safety and eliminates the need for costly = brackets. Available with threaded, butt = and socket=20 weld ends, the 304F is an outstanding choice as a universal valve for = all of=20 your fluid processing needs.

Installation and=20 Operation

Always install = your valve=20 according to accepted industry standards and practices and operate only = within=20 stated pressure, temperature and fluid media limits. Do not open or disassemble = valve unless=20 you intend to replace resilient seat and gasket materials. Repair kits are available from = your=20 local Inline representative or call = 1-800-568-8998.

Your 304F valve is = available=20 lever operated with our standard lockout device and incorporates an = integrally=20 cast dual pattern ISO 5211 mounting pad for electric or pneumatic = actuation.=20 Product specification sheets and technical drawings are available for=20 dimensional information required for proper installation and = automation.

Maintenance

Resilient seated = valve=20 products may wear over time resulting in loosening at component = boundaries. If leakage is detected, = tighten=20 according to the steps and torque values outlined below. If tightening does not correct = the=20 problem, it is time to replace your seats and = seals.

Repair

Remove=20 and Clean Valve

A. = If valve is in = line, make=20 sure system is purged and line, ball and cavity pressure are released = before=20 unbolting from piping system.

B. = Remove all add-on = components=20 such as actuators and set aside.

C. = Disassemble = valve. Remove old seats and seals and = discard=20 them. Clean and dry metal = components in preparation for reassembly.

Install Repair Kit and = Reassemble=20 Valve

Arrange cleaned = valve parts=20 on workbench. Position = body on its=20 side (top of the valve body facing you).

A. = Stem=20 Assembly

1. =20 Place thrust = washer on stem=20 sliding over threaded end and seating on shoulder at base. Place Viton o-ring on stem = sliding over=20 threaded end and seating into groove notched at mid-point of=20 stem.

2. =20 Insert stem into = body cavity=20 through side, threaded end first, and glide through the hole in the top = of the=20 body until seated.

3. =20 While holding stem = in place,=20 slide stem packing set over threaded end. =20 Stem packing should be stacked with mating concave/convex sides = facing=20 each other. Slide stem packing set over stem, concave piece first, until = seated.

4. =20 Place stem packing = follower=20 bushing over threaded end of the stem and lower over stem packing=20 set.

5. =20 Position spring = washers with=20 concave sides facing each other and lower set over stem bringing them to = rest=20 upon stem packing bushing.

6. =20 Thread stem nut = down stem=20 and hand tighten until stem and packing assembly are properly seated, = aligned=20 and fixed in position. = Tighten stem=20 nut to the minimum torque specified in Table 1 and rotate slightly more = until=20 stem nut flats are perpendicular to stem flats. This will allow you to slide = the lock=20 washer down stem and into position over stem nut. (Please note: torque should = not exceed=20 maximum indicated in Table 1.) =20 Thread second stem nut down over stem until resting on lock = washer to=20 keep stem assembly locked in place for further valve assembly and=20 adjustments.

B. = Ball/End=20 Caps

1. =20 Your 304F valve = has two (2)=20 end caps. Place new seats = in end=20 caps.

2. =20 Select one of the = two (2)=20 gaskets provided. Gently = insert the=20 gasket into the step machined into the side of the = body.

3. =20 Select one end = cap. Gently insert the end cap into = the body=20 until it rests against gasket.

4. =20 Place a bolt = through each of=20 four through holes around the outside of end cap.

5. =20 Turn body over=20 carefully. Make sure seat = is=20 properly positioned in end cap. =20 Orient the axis of the key at base of stem vertically so as to = facilitate=20 ball entry. Carefully = lower ball=20 into the body cavity gliding ball key way over stem key until cradled on = end cap=20 seat. Rotate ball 90=BA = to prevent=20 ball from moving.

6. =20 Gently insert the = remaining=20 gasket into the step machined into the other side of the body. Select the other end cap and = carefully=20 insert into the same side of the body making sure the bolts align with = the=20 through holes.

7. =20 Place a washer and = nut on=20 each bolt and loosely hand-tighten. =20 Continue hand tightening according to pattern in Figure 1 to = insure that=20 each bolt is secured to the same length. =20 Do not over-tighten any one bolt.

8. =20 Ball should now be = loosely=20 secure. Turn the valve = upright and=20 inspect to see that the stem is straight and ball orifice is aligned = with the=20 end cap bore holes. Use = of a=20 cylindrical dowel to properly align the axis of the ball between = opposing end=20 caps is highly recommended. =20 Continue hand tightening according to sequence in Figure 1 until = proper=20 alignment is secured.

9. =20 Once end caps are = on and=20 proper alignment is achieved, tighten each end cap bolt with a torque = wrench 1/4=20 turn alternating according to Figure 1. =20 Continue repeating this cycle until reaching the torque value = specified=20 in Table 2. This should = ensure=20 proper seating and ball alignment..

C. Final Assembly and = Test

1. =20 Your 304F ball = valve is now=20 ready for final assembly, adjustment, and testing. Remove top stem nut. Place stem spacer washers onto = lock=20 washer until higher than mounting pad surface. This will provide clearance = for hand=20 operation of the valve. = Place the=20 stop plate over stem and lower until coming to rest on stem spacer = washers. Next, slide handle over = stem. Hand-tighten stem nut until = handle is=20 fixed in place. Secure = with=20 wrench.

2. =20 Insert the stopper = into the=20 mounting pad and secure with nut and washer provided. This provides a fixed stop for = the stop=20 plate allowing for 90=BA rotation of the valve.

3. =20 Submit valve to = qualified=20 valve test facility for pressure test.

Your repaired 304F = ball=20 valve is now ready for installation and service.

Inline Industries = makes a=20 number of other fluid processing valves which complement this offering. = Please=20 consult your local Inline representative for more information about our = products=20 or call 800-568-8998 for more details. =20 Thank you for purchasing an Inline product. =
