Burkert 20007953 Type 2032 is an externally controlled diaphragm valve consisting of a pneumatically operated piston actuator, a PTFE/EPDM diaphragm, and a stainless steel T-valve body. The proven and robust PPS actuator ensures reliable 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 in the food, beverage, and pharmaceutical industries.

Control Functions

Control function A (CF A): Pneumatically operated T-valve, normally closed by spring force in the rest position.

Performance Specifications

Maximum permissible operating pressure for control function A (Stainless steel body, PTFE diaphragm):

Diaphragm size	Actuator size	Pilot pressure [bar]	Dynamic [bar]	Static [bar]
40	100 (G)	5.5–7	6	9
40	125 (H)	5.5–7	10	10

Risk of bursting due to overpressure

If the device bursts, escaping media may cause injuries, burns or scalds. Do not exceed the maximum permissible pilot pressure or maximum permissible operating pressure. Observe specifications on the type label.

Installation for leakage detection

One of the relief bores in the diaphragm bonnet for monitoring leakages must be at the lowest position to ensure proper drainage and immediate visual indication of diaphragm wear.
