• The structure is simple, and the gate plate and valve seat assembly are easy to replace;

• The integral gate is used and can be used in both directions to increase service life;

• The thrust bearing has large load capacity, and the rubber-plastic composite lip-shaped

  valve stem packing minimizes the switching torque;

• The threaded valve stem packing gland allows the bearing and valve stem packing to be

  replaced when the packing is under pressure;

• A new type of closed groove sealing ring is used between the valve body and the valve

  cover, connected by studs, with simple structure and reliable sealing;

• The bearing seat is equipped with a lubricating oil nozzle to facilitate on-site filling of grease;

• The surface of the gate plate and valve seat is sprayed (stacked) and welded with special

  carbide to make them have good wear resistance and corrosion resistance.

• A wave spring is installed between the valve body and the valve seat, and a wave spring

  is installed between the gate plate and the valve seat. A good metal seal can be maintained

  between the gate plate and the valve seat under low pressure;

• The gate plate is fully floating, so the valve should rotate 1/4 turn after the opening and

  closing operations are in place.

Note: 

      The valve is absolutely not allowed to be in a half-open and half-closed state under

       pressure. This will cause great damage to the valve plate and greatly shorten the service life of the valve.
