* Strahman piston extensions are measured from the height of the RF for an ANSI standard ange. For ANSI 600 class valves the extension is equal to the actual RF provided
by Strahman. For ANSI 150 and 300 class valves the ANSI standard RF height is 1
/
16” while Strahman provides 3
/
16” height for piloting as standard. Customers can request
a 1
/
16” RF height for RF-to-RF ange installation and the piston extension will equal the actual distance from the RF. For the Strahman standard (3
/
16” height) the distance
measured from the RF to the tip of the piston will be ⅛” less than the description. Example: 2” ANSI 150 Drain Valve with 6” piston extension will measure 5 ⅞” from a
standard Strahman RF to the tip of the piston. Piston Extension tolerances tighter than ⅛” available upon request.

* Dimensions G, H, L are for Air-Operated Drain Valves. For Hydraulic Drain Valve dimensions, please consult factory. Strahman piston extensions are measured from the height of the
RF for an ANSI standard ange. For ANSI 600 class valves the extension is equal to the actual RF provided by Strahman. For ANSI 150 and 300 class valves the ANSI standard RF
height is 1
/
16” while Strahman provides 3
/
16” height for piloting as standard. Customers can request a 1
/
16” RF height for RF-to-RF ange installation and the piston extension will equal the
actual distance from the RF. For the Strahman standard (3
/
16” height) the distance measured from the RF to the tip of the piston will be ⅛” less than the description. Example: 2” ANSI
150 Drain Valve with 6” piston extension will measure 5 ⅞” from a standard Strahman RF to the tip of the piston. Piston Extension tolerances tighter than ⅛” available upon request.

* Strahman piston extensions are measured from the height of the RF for an ANSI standard ange. For ANSI 600 class valves the extension
is equal to the actual RF provided by Strahman. For ANSI 150 and 300 class valves the ANSI standard RF height is 1
/
16” while Strahman
provides 3
/
16” height for piloting as standard. Customers can request a 1
/
16” RF height for RF-to-RF ange installation and the piston extension
will equal the actual distance from the RF. For the Strahman standard (3
/
16” height) the distance measured from the RF to the tip of the piston
will be ⅛” less than the description. Example: 2” ANSI 150 Drain Valve with 6” piston extension will measure 5 ⅞” from a standard Strahman
RF to the tip of the piston. Piston extension tolerances tighter than ⅛” available upon request.

•Figure 025 for large sizes use a non-rising stems to minimize overall length.
BODY ARRANGEMENTS
Strahman Bottom Disc design is a vessel outlet valve. When opening, the disc retracts completely
into the valve body. This provides an unrestricted full flow. In combination with maximized port sizes, this
design offers maximum flow capacity.
Strahman valves are available in a choice of options including material of construction, seat
arrangements, sealing systems to atmosphere, actuators and customized or standard connections to
piping. Other specific features are full jacketing, vacuum package and dead space free connections
to vessels.
Typical applications include the draining of viscous products especially in combination with low pres-
sure and/or vacuum processes.

Vessel Pad Vessel Nozzle Pipe Assembly Pad
Custom Vessel Pad
To connect valves to existing vessels or reactors, there are two possibilities: a nozzle or a pad
connection. In both cases, the customer must specify the following vessel connection details:
« D» (inside diameter), « H» (height), DN (nominal size), PN (pressure rating) and connection
standard (ISO, ANSI, DIN, etc.). To eliminate retention areas radius « R» can be specified for
optional contouring. For new projects Strahman can supply valves with easy-to-fit standardized
pads that are ready to be installed.
VESSEL CONNECTIONS
SEALING SYSTEM
Soft Seal-The Soft Seal
is a seat-less sealing system
that assures superior per-
formance. While closing, the
plunger moves through the
valve bore and effectively
rods any remaining product
out of the valve.
Temperature
Min: -50o C / -60o F
Max: 200o C / 390o F
Pressure
Max: 100 bar / 1450 psig
Step 2
Valve is raised to
break through the
crust in the bottom
of the vessel
Step 3
Valve is opened
to the sampling
position
MULTI-POSITION & BOTTOM VESSEL SAMPLING
Strahman Soft Seal Valves allow the valve
to operate in multiple positions while main-
taining a seal between the process and the
outlet. It is a multi-position valve that serves
as a multi-purpose process tool.
