The Type 2974 manually operated diaphragm valve consists of a manually operated

actuator, a diaphragm and a T-valve body. The manual actuator with plastic

handwheel ensures use in hygienic or aggressive ambient conditions. The flowoptimised

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,

autoclavable 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.
