If you have any questions concerning this document or on how to handle SAMSON valves and tools correctly, you can contact us
as follows:–

Send an e-mail to SAMSON's After-sales Service (aftersalesservice@samsongroup.com)–

Call the after-sales service at your nearest SAMSON subsidiary or office. All addresses are available atwww.samsongroup.com.

2 Safety instructions and measures! WARNING
Damage to health after contact with hazardous substances.
Certain lubricants (e.g. 8150-4008) are classified as hazardous substances. These substances have a special label and a material
safety data sheet (MSDS) issued by the manufacturer.
Î Make sure that an MSDS is available for any hazardous substance used. If necessary, contact the manufacturer to obtain an
MSDS.
Î Inform operating personnel about the hazardous substances and their correct handling.

3 Special tools for tightening torques
Special tools are required to assemble and remove some parts. Use adjustable torque wrenches with a stop signal or that indicate
the torque being applied to achieve the right tightening torques.
Valves in large valve sizes often require tightening torques that can only be achieved through additional torque multiplication byusing a torque multiplier or hydraulic power tool.

Types of pressure balancing

SAMSON valves have different types of pressure balancing. The parts subject to wear and spare parts for the various types ofpressure balancing are not interchangeable. Therefore, it is important to always specify or check the pressure balancing used
when ordering spare parts, for repairs and after-sales inquiries. The configuration ID or the SAMSON order number (including
position within the order) is necessary in this case.

Tightening torques

2 Tightening torques
Note concerning the following specifications–

All tightening torques specified in Nm–

Tightening torque tolerance: ±10 %–The tightening torques are based on a friction coefficient of 0.06 with a lubricated seat thread and facing.

–

After long operating times or long periods or use at temperatures above 250 °C, the breakaway torque may be twice as highas the tightening torque.

–

Certain valves (e.g. Type 3248) have their own tightening torques. Refer to the documentation for specific valve models.

Note on different seat wrenches for Type 3241 (DN 250/NPS 10)

Until July 2003, the same body was used for Type 3241 Valves and self-operated regulators in sizes DN 250/NPS 10, regardlessof the body material used.
After July 2003, a new body was used for Type 3241 Valves in DN 250/NPS 10. As a result, a different seat wrench is required
for the new body (see table). This does not apply to self-operated regulators, which still use the original bodies. Other seat/plug
trims are used for the new body of Type 3241 Valves.

Note on special versions of Type 3248

Note
The Type 3248 Valve is available in various special versions that differ from the standard version, e.g. in valve size, pressure rating and materials used. These special versions were originally manufactured according to the customer specifications. As a result,the special versions are listed along with the name of the customer in this document, even in cases where these originally special
versions have become standard.

Note on versions of Type 3246

Note
The Type 3246 is based on the Type 3241, Type 3251 or Type 3244 Valve, depending on the valve style and pressure rating. The
required tools vary accordingly. Therefore, it is important to always specify or check the version used when ordering spare parts,
for repairs and after-sales inquiries. The configuration ID or the SAMSON order number (including position within the order) is
necessary in this case.
Design of Type 3246
All versions of the Type 3246 Valve contain the following components:–

Long insulating section–

Circulation inhibitor, consisting of:––––White PTFE-silk cords from adjustable packing
Threaded bushing 2.4360 (Monel) or 2.0402 (brass)
Grub screw (hex socket) to secure the threaded bushing
Packing spring or brass sleeve (the latter requires more packing rings)

A top-entry design is not used for these valves.
Since September 2007, the overall heights have changed and various cover plates for air separation units (ASU) and hydrogen/carbon monoxide (HyCO) plants are available for Type 3246 Valves.

Note on the use in air separation units (Type 3246 and Type 3248)! WARNING
Risk of injury due to incorrect handling of oxygen.
Type 3248 and Type 3246 Valves are frequently installed in air separation units used to produce oxygen. Precautions must be taken to prevent a possible fast reaction of oxygen, which can lead to combustion and explosions.
Î Maintenance staff must attend a training at SAMSON lasting several days before they are allowed to perform any maintenance work on valves installed in air separation plants.

Note
Due to continuous development of the Type 3248 Valve and the numerous special versions that are available, further tools are required in addition to the basic tool kit (1280-3047). These tools are not part of the basic tool kit and must be ordered separately.
Note
The basic tool kit (1280-3047) includes a torque multiplier for tightening using the gear (1990-5125). This torque multiplier is currently listed under the material number 1990-5139 and has a gear ratio of 1:20 (as of 2015). Earlier versions of the basic tool kit
included a torque multiplier listed under material number 1990-5126, which had a gear ratio of 1:18.5.
Before assembly, check which torque multiplier you are using and which gear ratio applies as a result.

Certain lubricants (e.g. 8150-4008) are classified as hazardous substances. These substances have a special label and a material
safety data sheet (MSDS) issued by the manufacturer.
Î Make sure that an MSDS is available for any hazardous substance used. If necessary, contact the manufacturer to obtain an
MSDS.
Î Inform operating personnel about the hazardous substances and their correct handling.

Types of pressure balancing

SAMSON valves have different types of pressure balancing. The parts subject to wear and spare parts for the various types ofpressure balancing are not interchangeable. Therefore, it is important to always specify or check the pressure balancing used
when ordering spare parts, for repairs and after-sales inquiries. The configuration ID or the SAMSON order number (including
position within the order) is necessary in this case.

1.4

Note on specifications

The construction of Series 280 Steam Conditioning Valves is based on that of Series 250 Valves. Therefore, the specifications apply
to both Series 250 and Series 280, if not explicitly specified.

Tightening torques

2 Tightening torques
Note concerning the following specifications–

All tightening torques specified in Nm–

Tightening torque tolerance: ±10 %–The tightening torques are based on a friction coefficient of 0.06 with a lubricated seat thread and facing.

–

After long operating times or long periods or use at temperatures above 250 °C, the breakaway torque may be twice as highas the tightening torque.

–

Certain valve models (e.g. Type 3259) have their own tightening torques. Refer to the documentation for specific valve models.

Note concerning the following specifications− All tightening torques specified in Nm− Use a torque wrench to apply and check the tightening torques.

2.1

Tightening torques for connection of valve and pipeline! NOTICE
Risk of valve malfunction due to incorrect tightening torques.
The bolted joint connection between the valve and pipeline exerts pressure on the retainer in the valve. In turn, this exerts pressure
on the seat ring and helps seal the ball.
Î Observe the specified tightening torques to ensure the valve functions properly.

Note on replacing the trim

Note
Different seat threads (M10x1 and M16x1) are assigned to the KVS ranges 0.0001 to 0.4 and 0.63 to 1.6. Therefore, the trims are
only interchangeable in the same valve size within the specified range.
! NOTICE
Incorrect control performance due to a combination of trim parts that do not match each other.
The trim parts (seat, plug, anti-rotation fixture and body gasket) are matched to exactly fit each other. The trim parts are delivered
together and marked accordingly (see associated valve documentation u EB 8091 and u EB 8091-1).
Î Only install matching trim parts.

Tightening torques

Note− After performing any repair or maintenance work on the actuator, renew the adjustable clamp.
− Actuators with 120, 175, 355, 750, 1000 and 2800 cm² actuator areas do not have an adjustable clamp.
− Versions of the 1400 cm² actuator exist with and without adjustable clamp. Therefore, it is important to always specify or checkthe version used when ordering spare parts, for repairs and after-sales inquiries. The configuration ID or the SAMSON ordernumber (including position within the order) is necessary in this case.
