The valve stem packing is manufactured from a specially structured composite material, reducing the valve opening/closing torque while ensuring sealing performance.
The sealing surfaces of the gate and seat undergo spray welding treatment followed by precision machining, achieving high surface hardness and accuracy. This provides excellent gas sealing performance with resistance to high pressure and corrosion.
A locking nut is installed between the throttle valve nut housing and the valve stem. When the valve stem is adjusted to a specific position, it can be locked to ensure a constant gas (or liquid) flow rate;
The throttle valve stem is made of special corrosion-resistant material. The valve needle is made of hard alloy, and the valve seat is embedded with hard alloy, providing excellent erosion resistance and corrosion resistance.
