Advantages

Cast carbon or alloy steel valve body and gate

Resistance to chemical and temperature effects of line medium.
Full bore gate body construction. Lowest flow friction factor.
Clear pass for maintenance and diagnostic equipment.
Corrosion-resistant over welding of the valve internals. Increased reliability and service life of the gate valves.
Pressure relief plug in the cover. Pressure relief.
Additional tightes of the gate (by boosting pressure inside).
Rolling bearings in the yoke. Decrease effort of the actuator.
Easer valve operation.
Usage of thermo expanded graphite for sealing  gland. Less stem friction wear-out.
Extended service life of the element.
