Product overview
The design of thrust bearing makes the valve easy and flexible to open.
The top mounted stem nut makes the valve in the open position. Even if the thousand wheel, stem and RAM are removed, they will not fall.
The packing is made of flexible graphite material with reliable sealing performance. Packing spacer ring and grease filling structure can be provided when required by users.
The design of sealing on the valve can ensure the packing and reliable sealing when it is fully opened.
Lift valve stem. The stem and the gate are connected by dry groove, and the stem head is forged as a whole to ensure sufficient connection strength.
