1) The valve disc is set in the position indicated by the solid lines in Fig. 1 prior to

shipment from the factory. If the valve is opened or closed after unpacking, it

must be reset in this position before installation. Failure to do so may result in

damage to the surface of the valve seat during handling and installation.

2) The valve must not be dropped or come in contact with other objects, as the

sealing surfaces of the disc and or valve seat may be damaged.

3) Care must be used during piping installation to ensure that pipe or flanges are

properly aligned so that the valve disc does not come in contact with them.

Misalignment as shown in Fig. 2 will result in damage to the valve.

4) The installed valve must never be opened or closed when foreign matter such

as sand is present in the pipeline.

Installation Procedure

To avoid interference the piping ID must be equal to or larger than the D dimension shown in the following

chart. If Pipe interference is evident spacers or chamfering of the pipe or fitting is required. Fig. 3

Procedure

1) Install the valve between flanges with valve slightly open. Fig. 4

2) Insert bolts, nuts, washers and tighten the bolts and nuts temporarily by hand.

3) Open the valve fully to check for pipe interference before fully tightening

the bolts.

The parallelism and axial misalignment of the flange surface should be under

The values shown in the below table to prevent damage to the valve.

4) Tighten the bolts and nuts gradually using a torque wrench to the specified torque value in a diagonal

manner. Fig. 6

Installation Procedure for Handle

Install the handle on the valve stem. Set the direction to correspond with the indication line at the top of

the stem, which should agree with the disc position.

1) Secure the handle at the top of the stem with the enclosed bolt and washer

using a socket wrench.

2) Set the cap on top of the handle, aligning the marks and gently strike with a

plastic hammer until seated.

Removal Procedure

1) To remove cap, insert a flat head screwdriver into the indentation and pry up

2) Remove the bolt and washer using a socket wrench, then remove handle.

Adjustment for the travel stop Gear type

The adjustments for Full Open and Full Closed positions are preset at the

factory. If adjustment is required refer to the following procedure:

Adjustment for Full Closed (Open)

1) Remove protective rubber caps

2) Loosen stop bolt with allen key

3) Adjust disc to desired position

4) Tighten stop bolts at end positions

5) Replace protective rubber caps

Note: You can only adjust 1 stop bolt at a time at the

end of travel in each position. If stop bolt is hard to

turn, rotate hand wheel 1 turn in opposite direction to

relieve pressure on gear, then reset disc position and

tighten stop bolt.

Operating procedure

- Open and Close the valve by turning handle slowly. Turn clockwise to Close, counterclockwise to

Open.

- Lever Type – The direction of the handle is the same as the disc

For full Closed position, the handle is perpendicular to the piping

For Full Open position, the lever handle is parallel to the piping system.

- Gear type

For full Closed, the indicator shows Shut.

For full Open, the indicator shows Open.

General operating Instructions

- Operate the valve within the pressure vs. Temperature range as per table below, otherwise the

valve can be damaged

- Select a valve material that is suitable for the media. (Refer to Chemical Resistance on AV Valve)

- Do not step on valve or apply excessive weight (the valve can be damaged)

- Allow sufficient space for maintenance and inspection

- Keep the valve away from excessive heat or fire. (Valve can become deformed or destroyed)

- Make sure to properly dispose of used valves. (Poisonous gas is generated when burned

improperly)

Caution: Do not attempt to repair or replace parts while valve is under pressure.

Refer to Asahi/America Type-57P Operation and Maintenance manual for Disassembly/Assembly or valve

repair.

General Instructions for Transportation, Unpacking and Storage

- Keep the valve packed in original carton box as delivered until installation

- Keep the valve away from any coal, tar, creosote (antiseptic for wood) termite insecticide,

vermicides and paint. (Could cause swelling and damage to the valve)

- Do not impact or drop the valve (It can be damaged)

Visual Maintenance Inspection

1) Check for flaws, cracks, or deformation of the valve.

2) Check for any leaks to the outside of the valve.

3) Check for seat/disc deformation due to improper installation of the valve.

4) Check for smoothness of handle operation.
