Tank bottom diaphragm valve with manually operated

actuator (FullFunction)

• Valve body and diaphragm are available in different materials

and versions

• Wetted surfaces from Ra ≤ 0.38 µm...≤ 1.6 µm

(optionally electropolished)

• Available in all common connection sizes and variants

• Integrated locking

• Minimum and maximum stroke limitation

The Type 2975 manually operated diaphragm valve consists of a manually oper-

ated actuator, a diaphragm and a tank bottom valve body. The manual actuator

with plastic handwheel ensures use in hygienic or aggressive ambient conditions.

The flow-optimised valve body with minimum dead space enables high flow values

and a wide range of possible applications. The valve body and the diaphragms are

available in all common materials and versions. The actuator has a compact, auto-

clavable design and is compatible with all other Bürkert diaphragm valves. An

explosion-proof ATEX/IECEx device variant is available. The manual actuator

possesses a visual position indicator with reproducible stroke scale. The actuator

also possesses an adjustable minimum and maximum stroke limitation and/or

locking. The manual actuator can be optionally equipped with sensors for position

feedback.
