Isolation Valve (Hydrant/Air)
Our range of isolation valves provide isolation of hydrants and air valves in applications that require safe and easy maintenance.
High strength 431 stainless steel spindle.
Corrosion resistant in a variety of applications.
Thermally bonded polymeric coating for long life corrosion protection.
All valves are hydrostatically factory tested and certified.
With a simple installation process under all weather conditions, there’s no polyethylene welding required for this product to support your pipeline.
The product’s high strength and impact resistant body is manufactured from ductile iron, with an EPDM encapsulated gate.
This full bore design eliminates potential debris build up, and provides axial thrust restraint when used on polyethylene pipe systems.
