When the valve is opened or closed, the sealing surface of the valve body and the sealing surface of the gate are always in contact. The sealing surfaces have an automatic lapping function, preventing impurities such as tar and dust from adhering to the sealing surfaces, thus maintaining a tight sealing effect at all times.
The entire valve undergoes shell and sealing tests using gas to ensure no leakage, making it safe and reliable.
Bi-directional hard sealing provides excellent sealing performance and long-lasting durability.
Utilizes our company's patented technology "Spring Pre-loaded Specific Pressure Valve Sealing Structure," ensuring the product's sealing performance.
The valve stem uses a large-lead thread transmission, enabling quick opening and closing.
Employs high-performance packing with minimal friction resistance, capable of self-lubrication and resistant to coal gas and various corrosive gases, ensuring flexible operation and reliable sealing.
The valve body is equipped with a blowing port, allowing the connection of steam, nitrogen, or inert gases to blow away accumulated dirt from the valve cavity and sealing areas.
The fluid resistance coefficient is extremely low, almost close to zero.
The valve port can allow pipeline cleaners to pass through for pipeline cleaning. A drain box is provided at the bottom for easy removal of dirt and impurities.
The valve transmission area is equipped with an oil injection hole, allowing timely lubrication of the valve stem and bearings to reduce friction resistance.
If required by the user, a valve stem dust cover and dust cap can be provided.
The valve installation methods are divided into three types: vertical, horizontal, and side-mounted. Horizontal and side-mounted installations must be specified when signing the contract.
