Type 2104 Pneumatically Operated Zero Dead Volume T-Valve Element

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

The Bürkert Zero dead volume T-Valve Type 2104 is designed for control of ultra pure, sterile, aggressive or abrasive fluids. It enables especially optimal sampling, draining or diverting of critical process fluids.

The valve body is machined from a single piece of block material (monoblock – no weld seam). The high quality diaphragms separate hermetically critical fluids from the actuator.

The pneumatic actuator is optimized for decentralized automation through ELEMENT pneumatic automation units. The fully integrated system has a compact and smooth design, integrated pneumatic lines, IP65/67, NEMA Type 4X protection class and superior chemical resistance.
