The manually operated diaphragm valve Type 3234 consists of a manually operated actuator, a diaphragm and a T-valve body. The manual actuator, optionally with a plastic or stainless steel handwheel, ensures use in hygienic or aggressive ambient conditions. The flow-efficient valve bodies with little dead space enable high flow rates and a wide range of possible uses. The valve body and the diaphragm 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 diaphragm bonnet and the handwheel are optionally available in plastic or stainless steel and are equipped with an integrated optical position indicator. The manual actuator can be optionally equipped with a stroke limiter, sensors for position feedback and a locking function.
