Key Product Characteristics of the Purge Valves
Some of the most important key features of our designed and manufactured purge valves are,
Cost effective
Units designed with an operating parameter pressure rating of up to 689 bar and 10,000 psig. It is measured at CWP.
The Purge Valve is designed with an orifice size which measures 3.20mm or 0.125 inches
The flow co-efficient value of our designed Purge Valves is taken to 0.25Cv.
Each unit is designed with a sophisticated vent hole structure, built to help the purge cap bleed out or drain the system pressure for safety
The vent tube which is part of the valve design, is used to direct away any excess gas or liquid from the operational system line
We offer a variety of Purge Valve end configurations to choose from, which include the BSPT pipe connection, our
Well Lok tube fittings, as well as the female/male NPT to suit our customer needs.
Our unique vent tube design feature in the purge valves helps to avoid any accidental removal of the stem part of the product during operations
All purge valves are designed to be heat code traceable with the material test report certified as per industry standards
The temperature rating of the purge valves as per their operating parameters is measured to be -54C to around 454⁰C.
Purge valve material of construction: Sealexcel serves as purge valve suppliers and offer high quality industry standard units designed with the SS316 material for construction. The cap, spring, ball and body of the purge valves are designed with the SS316, to ensure high end durability in all pressure industrial conditions.
