Type 2103 Pneumatically Operated 2/2-Way Diaphragm Valve Element

Brand: Burkert Fluid Control Systems
Does not ship to Virginia, United States

The externally piloted diaphragm valve type 2103 consists of a pneumatically operated piston actuator, a diaphragm and a 2-way valve housing made of cast stainless steel.

The high quality actuator with a stainless steel cover is designed for usage in hygienic or aggressive environments. The how optimized and zero dead volume valve body makes high how rates possible and a variety of applications to be realized.

The design enables the easy integration of automation modules whether they are electrical/optical position feedback, pneumatic control units, an integrated fieldbus interface or even an explosion proof device versions.

The fully integrated system has a compact and smooth design, integrated pneumatic lines, IP65/67, NEMA Type 4X protection class and superior chemical resistance.
