Type 2032
Burkert Type 2032 T-diaphragm valve with pneumatic plastic actuator (CLASSIC). The externally controlled diaphragm valve Type 2032 consists of a pneumatically operated piston actuator, a diaphragm and a T-valve body. The proven and robust actuator with a plastic housing 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 (PPS variant). The integration of the automation units Type 8690/8697 is possible in all configuration levels (can be retrofitted). An explosion-proof ATEX/IECEx device variant is available.
The add-on body is optionally available in plastic or stainless steel. The actuator is equipped with an integrated, optical position indicator as standard, optionally a minimum/maximum stroke limiter can be installed.

WARNING
For low operating pressures, optional variants with reduced spring force (EC04) are recommended. Pressure data [bar]: Overpressure to atmospheric pressure. Static: When closed, the valve is pressurised on one side with the maximum operating pressure.
Installation
Self-Draining Installation
To ensure self-draining, the pipeline should have an inclination angle of 1° to 5°. The self-draining angle of the valve body depends on the body size and port connection.
Leakage Detection
For leakage monitoring, one of the relief bores in the diaphragm bonnet must be located at the lowest point.
