The externally controlled diaphragm valve type 2103 consists of a pneumatically operated piston actuator, a diaphragm and a 2-way valve body. The proven and robust actuator with valve housing made of stainless steel ensures use under hygienic or aggressive environmental conditions. The flow-optimised valve housings with low dead space enable high flow rates and a wide range of applications. The valve body and diaphragm are available in all common materials and variants. The drive has a compact autoclavable design with a large stainless steel shell and gap-free seals. The integration of ELEMENT automation units is possible in all configuration stages (can be retrofitted) and can be equipped with an integrated fieldbus interface. An explosion-proof ATEX/IECEx device variant is available. It is a compact, smooth and highly integrated system consisting of valve and automation unit with integrated control air ducts (no intake of ambient air). The diaphragm base is available in either plastic or stainless steel (360° rotatable). The valve is protected according to protection classes IP65/67 and NEMA Type 4X and has a high chemical resistance.
