    Elastic Seat Gate Valve Soft Seal Gate Valve Industrial Valve Cast Iron Gate Valve Flange Gate Valve
    A cast iron flexible seat soft seal gate valve is a shut-off valve that uses a cast iron body and a flexible wedge or gate with a rubber or EPDM coating for sealing against the valve seats . These valves offer excellent sealing performance and are suitable for low-pressure, non-corrosive fluids like water and sewage, though they are susceptible to wear from abrasive fluids. The flexible seat provides a tight seal by deforming slightly to compensate for any valve misalignment, making them a common and cost-effective choice for water supply and drainage systems.
    How it Works
    • Body:
      The valve body is typically made of cast iron, which is durable and low-cost for non-corrosive applications.
    • Wedge (Gate):
      A flexible wedge, often coated with a soft material like EPDM or NBR rubber, is used to block and seal the flow.
    • Seat:
      The flexible wedge presses against the seat (which can be part of the valve body or a separate ring) to create a watertight seal.
    • Flexible Sealing:
      The rubber-coated wedge deforms to create a good seal, effectively compensating for any minor misalignments in the valve or pipeline.
    Advantages
    • Excellent Sealing:
      The soft seal provides superior sealing compared to metal-seated gate valves, reducing leakage.
    • Low Fluid Resistance:
      The straight-through design of the valve body offers minimal resistance to fluid flow.
    • Cost-Effective:
      Cast iron is a low-cost material, making these valves an economical choice for many applications.
    • Versatility:
      Suitable for water, sewage, and other non-corrosive fluids.
    Disadvantages
    • Wear from Abrasive Fluids:
      The constant rubbing of the soft seat can lead to wear, especially when passing through particle-laden fluids.
    • Limited Pressure/Temperature:
      Standard cast iron bodies are best suited for low-pressure and low-temperature environments.
    • Slower Operation:
      Like other gate valves, they are primarily for on-off service and are slower to operate than other valve types.
