Type 2032
BURKERT Type 2933 manually operated diaphragm valve consists of a manually operated actuator, a diaphragm and a 2-way 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 actuator has a compact, autoclavable design and is compatible with all other Bürkert diaphragm valves.

Installation
Risk of injury due to high pressure and escaping medium
Switch off the pressure before working on the device or system. Vent or empty the lines.
Installation Position
Installation position: any, preferably actuator facing up. To ensure self-draining, the angle of inclination should correspond to the angle of inclination of the pipeline.
