Key Product Characteristics of the Purge Valves

Some critical features and product specifications of our bleed valves are:

Convenient and compact piece installation design

Bleed valves available in a variety of configuration settings, that include the female/male NPT, our Well Lok tube fittings and the SAE pipe connection

Units are designed to be heat code traceable. The traceability has been linked to a certified material testing report

The operating parameter pressure rating is configured to reach up to 10,000 PSIG, and 689 bar at the CWP

Flow co-efficiency of the bleed valves is calculated to be at 0.25.

Our bleed valve orifice is 3.20mm or 0.125 inches

Our stainless steel bleeder valve has been designed with a vent tube which directs the excess gas or liquid right away from the line of the system

The sophisticated vent tube design of the bleed valves helps to avoid any kind of accidental stem removal

The operating parameters of the bleed valves come with a temperature rating of -54⁰C to around 454⁰C.

Materials of construction: We use SS316 as product unit material for the design and manufacture of our bleed valve components, that are the stem, vent tube and the body.
