Rising Stem Hard Seated Gate Valve

Rising stem hard seal gate valve is known for its high sealing and durability, and is suitable for high temperature, high pressure and harsh media conditions. Its hard seal adopts metal-to-metal structure (such as stainless steel gate and carbide valve seat), with a temperature resistance of more than 500℃, high pressure resistance (such as Class 600/900), strong resistance to particle erosion and corrosion, and avoids the risk of soft seal aging and leakage. The rising stem design exposes the valve stem, which can intuitively display the opening, facilitate operation and monitoring, and the valve stem is isolated from the medium, with multi-layer packing seal to reduce corrosion hazards. The valve body is made of high-strength cast steel or alloy material, which is resistant to pressure and deformation; the gate guide is precise, the opening and closing torque is small, and it can be adapted to worm gear or electric actuator. The hard seal surface is precision ground or sprayed, with self-cleaning ability, and can be adjusted to compensate and restore the seal after wear to extend the service life. The modular structure supports quick replacement of parts and convenient maintenance. Combining its advantages of extreme working conditions resistance, reliable sealing, intuitive operation and efficient maintenance, it is widely used in high temperature and high pressure fluid control in petrochemical, electric power, metallurgy and other fields.

Resistant to high temperature and high pressure: metal hard seal structure (such as stainless steel + carbide), temperature resistance over 500℃, pressure resistance up to Class 600/900, and particle erosion resistance.

Reliable sealing: precision ground sealing surface, strong self-cleaning ability, adjustable compensation after wear, and prevent leakage.

Visual operation: exposed stem design, intuitive display of opening, easy to monitor and adjust.

Corrosion resistance and long life: valve stem is isolated from the medium, multi-layer packing seal, high-strength valve body anti-deformation, adaptable to harsh media.

Easy maintenance: modular structure supports rapid replacement of parts, reducing maintenance costs and downtime.

Wide application: key control equipment for high temperature and high pressure fluids in the fields of petroleum, chemical, and electric power.
