51000 Valve

D103339X012

Baumannt 51000 High-Pressure,
Low-Flow Control Valve

The Baumann 51000 control valve is optimally
designed for demanding low-flow, high-pressure
control applications often found in laboratories and
pilot plants. NPS 1/4 or 1/2 valve assemblies are
standard as either investment cast stainless steel or
N10276 nickel alloy. Constructions with other high
nickel alloys are available.

With a small footprint, less than 10 inches tall, and
multiple trim capacity reductions available to meet
changing process requirements, the 51000 is a perfect
fit where space is at a premium and flexibility is a must.
The valve is suited for demanding control of gases,
chemical/dye injection and acid/caustic solutions in
paper production, textiles, specialty chemicals, and
many other industries.

The PTFE ring (key 3B) surrounds the valve plug (key 4)
to help eliminate clearance flow typical of lapped-in
metal-to-metal close clearance micro trims. Flow is
directed over the valve plugandforcedthrougha
single V-notch path as the plug moves above the PTFE
ring, providing precise and predictable control over its
entire travel range. When the V-notch moves below
the PTFE ring, Class VI primary shutoff is achieved.

A live-loaded metal seat collar (key 3C) fully retains the
PTFE ring (key 3B). The valve plug (key 4) seats against
the metal collar providing Class IV secondary shutoff.

In addition, the fluid process pressure combines with
the actuator seating force to form a hydraulic seal
within the fully retained PTFE ring (key 3B). Therefore,
