Brief: Ever wondered how a non-rising stem gate valve can optimize your pipeline operations? This video provides a detailed walkthrough of the Cast Iron Soft Sealing Non Rising Stem GGG50 Gate Valve, showcasing its unique design where the stem remains concealed within the valve body. You'll see how its resilient seated construction ensures reliable bidirectional sealing and learn why its compact design is ideal for space-constrained installations like underground pipe galleries.
Related Product Features:
  • The valve features a non-rising stem design where the stem rotates in place and does not protrude outside the valve body.
  • It utilizes a soft-seal mechanism with elastic materials like EPDM, NBR, or PTFE for reliable bidirectional sealing.
  • The resilient seated construction compensates for manufacturing errors and temperature deformation to ensure long-term sealing reliability.
  • With a smooth flow channel and minimal pressure loss, it is suitable for high-flow conditions in pipeline systems.
  • Its compact and lower height design makes it ideal for installation in space-constrained areas such as underground pipe galleries.
  • The valve is constructed with durable materials including a ductile iron body, stainless steel shaft, and brass internal components.
  • It operates only in fully open or fully closed positions and is not designed for regulation or throttling applications.
  • Available in a wide range of nominal diameters from DN50 to DN600, with an operating temperature of up to 200°C.
Pertanyaan:
  • What is the operating principle of the non-rising stem in this gate valve?
    The valve stem is connected to the gate plate through threads and rotates in place when the handwheel is turned, driving the gate to rise or fall without the stem protruding outside the valve body, making it ideal for confined spaces.
  • What materials are used for the key components to ensure durability and sealing?
    The valve body, disc, and bonnet are made from ductile iron, the shaft is stainless steel 420, the wedge nut and thrust washer are brass, and the primary sealing elements like the seat and O-rings use EPDM for reliable elastic sealing.
  • What are the typical applications and installation advantages of this valve?
    This valve is suitable for high-flow pipeline systems and is particularly advantageous in space-constrained installations like underground pipe galleries and equipment floors due to its compact, non-rising stem design.
  • Can this valve be used for flow regulation or throttling?
    No, this gate valve is designed only for fully open or fully closed operation to start or stop flow and is not suitable for regulation or throttling purposes.
