**Key Features**
1. The manual part can be equipped with a steel plate restraint handle or a stainless steel casting handle. A limiting structure is included, allowing the valve to be locked at the open or closed position, preventing accidental operation.
2. The stem is made from A182F (1Cr13) forged material, treated for optimal hardness (HB220–250). It connects to the handle via flat key, spline, or square, offering strong versatility and ease of maintenance. The stem also features a blowout-proof design.
3. The valve uses flexible graphite sealing rings or PTFE graphene seals, providing reliable sealing under lubricated conditions.
4. Static prevention structures can be added to avoid static sparks, which could ignite flammable substances, ensuring system safety.
5. Different types of sealing pairs can be used depending on the working conditions, such as soft sealing, hard sealing, or fireproof valve seats. DN150 uses a floating ball, while DN200 uses a fixed ball.
6. An auxiliary sealing structure can be added, including a grease injection valve, enabling temporary sealing during emergencies and making it suitable for underground installations.
