The Model 500 Gate Valves prove versatility and interchangeability necessary for a wide range of demanding flow control applications, including manifolds and Christmas trees. The body and the bonnet are constructed of forged steel for maximum reliability and safety.

For severe applications, weld-clad corrosion-resistant alloy linings can be applied to base forgings for maximum protection for the valve’s internal service area.

Model 500 Gate Valves are also available in FORGED STAINLESS STEEL.
