Basic info of Risilient Rising Stem Gate Valve
- 1. Valve body: The body and bonnet of the rising stem gate valve are made of ductile iron, ensuring excellent strength and wear resistance. The stem lift feature allows easy monitoring and control of the valve, increasing its availability and efficiency.
- 2. Sealing: One of the key highlights of the rising stem gate valve is its resilient seat design. The valve adopts highly elastic rubber seat, which has excellent sealing ability, prevents leakage and ensures tight closing. So perfectly suitable for water supply and drainage, sewage treatment plants and industrial processes.
- 3. Disc: Covered disc design provides optimum flow characteristics and minimizes pressure drop. This reduces energy consumption and improves the overall performance of the system. Due to its low-torque operation, the valve opens and closes smoothly, and can basically be operated with a handwheel, reducing costs and improving operational safety.
