Type 3233 Manually Operated 2-Way Diaphragm Valve with Stainless Steel Body

Brand: Burkert Fluid Control Systems
Does not ship to United States

The manually operated diaphragm valve Type 3233 consists of a manually operated actuator, a diaphragm and a 2-way 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 add-on body 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.
