Type 2032
Burkert Type 2032 externally controlled diaphragm valve 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 actuator has a compact, autoclavable design (PPS variant).
Control Functions
- Control function A (CF A): Pneumatically operated T-valve, normally closed by spring force.
- Control function B (CF B): Pneumatically operated T-valve, normally opened by spring force.
- Control function I (CF I): Pneumatically operated T-valve on either side, switching position dependent on external control.
Approvals and Conformities
- Explosion Protection: ATEX (II 2G Ex h IIC T4…T2 Gb, II 2D Ex h IIIC T135 °C…T300 °C Db) and IECEx.
- Foods and Beverages / Hygiene: 3-A Sanitary Standards Inc., FDA (Code of Federal Regulations), USP Class VI, EC Regulation 1935/2004.
