Handwheel Hard Seated Gate Valve

The concealed stem handwheel hard seal gate valve is suitable for working conditions with limited space or concealed installation due to its compact structure and high reliability. Its valve stem is built-in and does not rise and fall with the gate, and the overall height is low, saving installation space, especially suitable for underground pipelines or equipment-intensive areas. The hard seal adopts a metal-to-metal structure (such as stainless steel gate and carbide valve seat), which is resistant to high temperature (up to 400°C or above), high pressure (such as Class 300/600), particle wear and corrosive media. The sealing surface is precisely ground, and the self-cleaning ability is strong during the opening and closing process, and the tightness is maintained for a long time. The handwheel directly drives the valve stem to rotate, the transmission ratio is optimized, the operating torque is small, the opening and closing is easy, and no external power is required. The valve stem is completely isolated from the medium, and is sealed with high-density packing to avoid the risk of external leakage; the valve body is made of high-strength cast iron or cast steel, which is resistant to pressure and impact. In addition, the concealed stem design reduces external exposed parts, has good protection, reduces the risk of environmental erosion, and has a long maintenance cycle. The valve has spatial adaptability, sealing reliability and easy operation, and is widely used in petrochemical, municipal water supply, ships and other occasions with strict requirements on installation space and sealing.

.Compact structure: The valve stem is built-in with concealed stem design, low height, space saving, suitable for installation in underground or dense areas.

.High temperature and high pressure resistance: Metal hard seal (stainless steel + carbide), temperature resistance 400℃+, pressure resistance Class 300/600, wear and corrosion resistance.

.Reliable sealing: Precision grinding sealing surface, self-cleaning and leakage prevention, long-term tightness.

.Effortless operation: handwheel drive, optimized transmission ratio, easy opening and closing without external power.

.Good protection: The valve stem is isolated from the medium, the packing is leak-proof, there are few external parts, it is resistant to environmental erosion, and the maintenance cycle is long.

.Wide application: petrochemical, municipal water supply, ships and other space-constrained scenes that require high sealing.
