Product Description

Pure-Flo Sample and Bleed Valves are available in Sample, Zero Static Sample, and Bleed, and with a number of standard and optional features to best suit your system design. Sample and Bleed Valves are manufactured from 316L stainless steel and utilize a thermoplastic handwheel so that they can withstand typical cleaning and sterilization protocols, including autoclaving.

The relatively simple design utilizing “off the shelf” o-ring seals allows for easy replacement of sealing components. The Sample Valve handle and stem are designed to provide smooth operation and limited wear on the internal components. The Zero Static Sample Valve can be installed directly in line and allows a sample to be taken or condensate to be drained without the typical hold up volume or contact surfaces inherent to branch valve assemblies.

The Bleed valve is a simple but effective design for providing a quick and easy way to asperate or drain a system. These are often used for filter housings, bubble traps, and small tanks. An optional weld end allows the bleed valve to become an integral part of any assembly.
