Maintenance

Take measures to prevent people from coming into direct contact with

product outlets. Failure to do so may result in burns or other injury from

the discharge of fluids.

CAUTION

Be sure to use only the recommended components when repairing the

product, and NEVER attempt to modify the product in any way. Failure to

observe these precautions may result in damage to the product or burns

or other injury due to malfunction or the discharge of fluids.

CAUTION

Valve Seat Replacement

Replacement of the valve seat with a new valve seat after approximately 100,000 cycles

depending on fluid quality and operation conditions will allow for prolonged use of the

product.

For instructions on valve seat replacement, see the Disassembly/Reassembly section.

Additional Tightening of the Valve Unit Gland Section

It is possible to further tighten the gland section in the valve unit. Where there is leakage

from the gasket or seal, tighten the gland section further using the following instructions:

1. Detach the handle unit (see instructions on p. 8).

2. Tighten, using the following steps:

1) Loosen the holder screw.

2) Tighten the holder further in with a socket wrench.

3) Retighten the holder screw.

Cautions when applying additional tightening:

Do not tighten the holder completely the first time. Do not tighten the holder any

more than is necessary to stop leakage.

If leakage continues even after the holder has been tightened, replace worn parts.

Disassembly/Reassembly

When disassembling or removing the product, wait until the internal

pressure equals atmospheric pressure and the surface of the product

has cooled to room temperature. Disassembling or removing the

product when it is hot or under pressure may lead to discharge of fluids,

causing burns, other injuries or damage.

CAUTION

Be sure to use only the recommended components when repairing the

product, and NEVER attempt to modify the product in any way. Failure to

observe these precautions may result in damage to the product or burns

or other injury due to malfunction or the discharge of fluids.

CAUTION

Do not use excessive force when connecting threaded pipes to the

product. Over-tightening may cause breakage leading to fluid

discharge, which may cause burns or other injury.

CAUTION

Use the following procedures to remove components. Use the same procedures in

reverse to reassemble.

(Installation, inspection, maintenance, repairs, disassembly, adjustment and valve

opening/closing should be carried out only by trained maintenance personnel.)

NOTE: 1. Reassemble the gland section after reassembling the valve section (see the

Disassembly/Reassembly of the Valve Section in the Disassembly/Reassembly

section).

2. When reinserting the spindle and valve shaft into the ball:

for the screwed model, finger-tighten the inlet union; for the flanged model, finger-

tighten the flange bolt. This serves as preparation for centering the ball.

When reassembly is completed, tighten the valve holder.
