Benefits
|
|
Cast carbon or alloy steel valve body and gate.
|
Resistance to chemical and temperature effects of line medium.
|
|
Full bore gate body design.
|
Free medium flow.
Clear pass for maintenance and diagnostic equipment.
|
|
Corrosion-resistant over welding of the trim.
|
Increased reliability and service life of the gate valves.
|
|
Rubberized gate.
|
Resistant to abrasive wear caused by movement of hard particles in medium flow.
|
|
Pressure relief plug in the cover.
|
Pressure relief.
Additional tightness of the gate ( by boosting pressure inside).
|
|
Hatch in the bottom part of the valve body.
|
Removal of sediment preventing full closure of the valve.
|
|
Rolling bearings in the yoke.
|
Decreased effort of the actuator.
Easier valve operation.
|
|
Usage of thermo expanded graphite for sealing gland.
|
Less stem friction wear-out.
Extended service life of the element.
