Bürkert T-diaphragm Valve with Manually Operated Actuator (Basic)

The Type 2934 manually operated diaphragm valve consists of a manually operated actuator, a diaphragm and a T-valve body. The manual actuator with plastic or stainless steel handwheel is available with a diaphragm bonnet made of stainless steel or plastic and 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 variants. 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 is equipped with an integrated visual position indicator, a reproducible stroke scale and an adjustable closing limiter. The manual actuator can optionally be equipped with sensors for position feedback.
