Description
The externally controlled diaphragm valve type 2031 consists of a pneumatically actuated piston drive, a diaphragm and a 2-way valve housing. The proven and robust drive with plastic housing ensures the use under hygienic or aggressive ambient conditions. The low flow and low dead space valve housings enable high flow values and a variety of applications. The valve body and diaphragm are available in all common materials and designs. The drive has a compact autoclavable design (PPS design). The integration of automation units 8690/8697 is possible in all levels (can be retrofitted). An explosion-proof ATEX/IECEx device variant is available.
The attachment housing is available either in plastic or stainless steel. As standard the drive is provided with an integrated optical position indicator, optionally a min. / max. Stroke limiter.
