NEOTECHA SAPRO® - TANK VALVE TYPE ST FOR ASEPTIC SAMPLING WITH BOTTLES

InstallatIon, operatIon and MaIntenance InstructIon

Before installation these instructions must be fully read and understood

1.4 Illegal technical changes

It is illegal to do mechanical changes of the design
of the Sapro tank valve, or to use parts of other
manufacturers for repairs, otherwise Neotecha
can not guarantee for the safety of the valve.

1.5 Warning of misuse

The Sapro tank valve with all connection pipes
and actuators can never be used to climb up or to
stand on it.

1.6 Danger sources

Chemical external
The sleeve on the actuator should not be cleaned
with solvents, Use alcohol or a mild detergent.

Mechanically

Valves for aseptic sampling of liquid mediums
stored in tanks.
Please read this installation, operation and
maintenance instruction carefully before you
handle the tank valve!

1 SAFETY

Enough space is needed to handle the tank valve,
to prevent of squeezing the hands while operating
the valve

Electrically
To prevent static charges, the entire tank valve is
made of conductive metal.

Please read these instructions carefully.

1.1 General danger potential

• Not paying attention to this instruction

• Incautious use or misuse

• Unqualified personnel or staff

1.2 Use as directed

The Sapro tank valve is used for aseptic
sampling from tanks into bottles.
The pressure range is between no pressure
(about 0,1 bar) and 10 bar maximum.
All material in contact with the product is
stainless steel 1.4435 (316L).
The soft seals are FPM (FKM).

1.3 Restricted use

The valve can be used only with products when the
materials used (1.4435 and FPM) are compatible.

Thermically
With a sample medium temperature range
between -10°C to 160°C, the surface of the tank
valve may assume the same temperature.
It is therefore necessary to wear gloves to avoid
injuries when operating the valve.

Dynamically
The valve is equipped with a “dead man” handle
(spring return). The handle will spring back
by itself when let go. This can cause injuries
to theoperators hand. Therefore do not let
thehandle go when enough sample is taken.

1.7 Requests for the operators

To ensure proper and consistent sample taking
the operator is to be trained as per users
sample taking instructions

3.1 Transportation

The Sapro tank valve is shipped in a box. Please leave the unit in this box until it is ready to
beinstalled.

3.2 Storage conditions

The Sapro tank valve has to be stored in a dry, dust-free place until it’s installed on the tank.

4 INSTALLATION

The tank has to be empty before any installation or repair of the valve can take place!

Preparation

The tank needs a 3” I-Line connection flange, welded to the outer surface of the tank wall.
The tank valve with the wet part is mounted with the I-clamp according following illustration:

5.2 Connections and valves
C1: Customer connection (Swagelok ⅛”) for:

a. Steam inlet to sterilize the sample passage in the actuator and bottle adapter in pos.1.
b. Inlet for any cleaning liquids before taking samples, depending on the medium to sample.

V1: Ball valve to control the inlet of the customer connection C1.
V2: By opening this valve the alcohol from the reservoir fills the inner part of the tank valve body.
V3: Drain valve to control the filling of the tank valve body from the reservoir when no samples

are taken. The body is only filled entirely when the alcohol flows through this valve down
drain 3.

V4: Drain valve for stem blocking media. By taking an alcohol sample at this point the state of

blocking media and the stem seal can be monitored.

V5: Actuator drain valve. Prior to sterilizing the sample passage this valve must be opened and

closed again when sterilizing process is completed.

Reservoir: The purpose of the reservoir is to ensure a constant head of blocking media

(alcohol) around the operator stem.

Bottle adapter: Aseptic sampling adapter for bottles with ISO GL45.
Pressure gage: Pressure gage to control the pressure coming from the customer

connectionC1.

6 MAINTENANCE

6.1 Cleaning

Though all parts of the Sapro tank valve are made of SS, they can be cleaned with normal cleaning
liquid. The O-rings can also be cleaned with normal cleaning liquid.

6.2 How to check the sample / blocking medium seal

The bearing is filled with the blocking medium (alcohol) coming from the reservoir and can be
checked by opening V3 to take a sample of the alcohol. If the alcohol is polluted with the sample
medium, the seal needs to be exchanged.

6.3 Exchange of the seat seal and O-ring

The tank has to be empty before any installation
or repair of the valve can take place!

• The valve seat, seat seal and the O-ring can

be dismantled by removing the four screws of
the Tri-clamp flange.

• The defective parts can now be exchanged,

please check all surfaces for scratches.

• When you screw on the Tri-clamp flange

again, please attach importance to the gap
(only about 0.3 mm) between the Tri-clamp
flange and the tank valve is the same all
around.
