Installation, Operation & Maintenance Instruction
(3 PC Body, Clamp / Butt Weld Ends, Sanitary Valve)
1. Scope: This instruction applies to 3-PC Body, Full Port Sanitary Valve, 400WOG (PN25); Clamp
Ends and Butt weld Ends; KV-09C/I, KV-091/I, KV-L9C/I, KV-L91/I according to ISO 2852，and
KV-09C/B, KV-091/B, KV-L9C/B, KV- L91/B according to BS 4825 & BPE. KV-L9C/I，KV-L91/I
and KV-L9C/B，KV-L91/B designed according to ISO 5211 mounting pad can be fixed with
actuator directly.
2. Warning (Restrictions on Use)
a. Temperature and Pressure Limit
yThe normal maximum operating pressure at maximum or minimum operating temperature is
shown on nameplate.
yThe operating temperature is within－290C to 2000C(if shell is WCB),or －400C to 2000C(if
shell is stainless steel) for PTFE or RTFE seat and sealing. Other seat and sealing operating
temperature shall be checked with KI Industries.
yThe nominal pressure (PN) rating describes maximum working pressure in cold operating
temperature (e.g. PN25 describes maximum working pressure 25 bar at －390C～400C).
b. Fluid limited
Since this valve is with soft seat, it is not suitable to granules liquor fluid or solidification fluid,
such as syrup.
c. No throttling operation
yDon’t leave the ball partly open where the pressure drop and/or flow rate damage to the valve
seats and/or ball.
3. Installation
a. Remove the rubber protective cover on clamp or butt welding ends, and clean or flush the valve
in fully open position(steam sterilization is allowed).
b. Prior to mounting, flush and clean the pipeline and valve to remove all accumulated extraneous
maters.
c. Installation of Clamp ends Ball Valves
1) Before connecting pipes with valves, should seal the connecting position with seal rings
according to standards ISO 2852
2) Should use quick clamps connect and fix the pipes and valves
d. Installation of Butt welding ball valves.
1) Keep valves in open position. lengthen butt welding ends can be welded directly: do
intermittent welding in four points of both butt welding ends.
2) if the butt welding ends is not lengthen, dismount cap bolts, but keep one bolts whose nut
should be loosen, and then the valve rotating freely.
