The manual stainless steel gate valve comes with two sealing types: flat and conical, making it adaptable to various operating conditions and medium requirements. Both sealing methods ensure stable sealing performance over long periods of use, contributing to an extended service life. Whether dealing with high temperatures, high pressures, or corrosive media, it provides reliable sealing effectiveness.
When in operation, turning the handwheel counterclockwise causes the valve stem to rise, quickly lifting the valve disc and diaphragm. This design ensures that the passage opens rapidly, allowing the medium to flow smoothly, and ensuring precise and efficient fluid control. The valve’s durable sealing and opening structure make it suitable for a wide range of industrial environments, meeting diverse operational needs
