API 6D DI Gate Valve with Blue Paint Designed to API 600 Standard

Product Description:

A cast iron gate valve is a type of valve used to control flow in piping systems, made primarily from cast iron material. Key features include:

  • Body - The main body and bonnet are made of cast iron, providing good strength and pressure handling. Common classes include Class 125, Class 250, and Class 800.
  • Gate - A rectangular or round gate made of cast iron or alloy steel slides into the valve body to control flow. The gate has a sealing surface on the edges.
  • Stem - The stem is made of alloy steel and connects the gate to the handwheel. It may be rising or non-rising.
  • Seat - Cast iron or alloy steel seat rings provide the sealing surface for the gate. The seats are pressed into the body.
  • Packing - Compressed fibrous packing prevents leakage around the stem.
  • Handwheel - A cast iron handwheel is bolted to the stem and allows manual operation of the valve.
  • End Connections - End connections are typically flanged, allowing connection to flanged piping. Threaded and socket weld ends are also available.

Cast iron gate valves are rugged and provide good shutoff when closed. They are primarily used for on/off applications in water, steam, oil and gas systems. Sizes range from 2-48 inches. Corrosion resistant coatings may be applied.


Features:

  • Durable cast iron body and bonnet - Provides strength, pressure rating, and corrosion resistance for long service life.
  • Rectangular or round cast iron gate - The gate slides into the body to control flow. Gate has sealing surfaces.
  • Rising or non-rising stem design - Rising stem indicates valve position. Non-rising stem requires less overhead space.
  • Replaceable seat rings - Seat rings provide seating surface for the gate. Can be replaced to refresh sealing.
  • Packing box and packing - Packing prevents leakage around the valve stem during operation.
  • Handwheel operator - Manual handwheel for opening/closing valve. Gives human operator control.
  • Flanged, threaded, or socket weld ends - Allows integration into various pipe types. Flanges allow easy installation.
  • Good shutoff capability - Cast gate with seating surface provides bubble-tight shutoff when closed.
  • Capable of throttling flow - Valve can partially open to throttle non-critical applications.
  • Variety of pressure class options - Classes like 125, 250, and 800 for range of pressure applications.
  • Coating options - Applied coatings improve corrosion resistance. Epoxy and fusion-bonded epoxy common.
  • Cost effective valve option - Quality cast iron construction at lower cost than many other valve types.

  • Wastewater systems - For flow control in sewer lines, lift stations, and treatment plants. Withstands exposure to sewage.
  • Fire protection systems - Provides reliable shutoff to isolate portions of wet or dry fire sprinkler systems.
  • Steam systems - On/off and isolation duties on steam distribution in factories, institutions, power plants.
  • Air and gas systems - Suitable for compression or distribution of air, natural gas, liquefied petroleum gas, etc.
  • Oil and fuel systems - For controlling flows of crude oil, fuels, and lubricating oils.
  • Chemical/petrochemical plants - Used in many chemical plant piping systems due to good corrosion resistance.
  • Heating/cooling systems - Provides flow control of hot or chilled water in HVAC and industrial applications.
  • General industrial - Widely used in manufacturing, processing plants for controlling various fluids.
  • Plumbing - Employed in larger commercial and industrial plumbing applications.

FAQ:

  1. What are the main features of cast iron gate valves?

Cast iron gate valves feature large body volume, heavy weight, and strong impact resistance. The cast iron material provides good corrosion resistance suitable for various industrial and water supply pipelines. Cast iron gate valves are also relatively low cost.


  1. What are some common issues with cast iron gate valves?

The most common issues with cast iron gate valves are valve jamming, seat leakage, difficult handwheel operation, and external corrosion. Regular maintenance is required, such as re-greasing, packing adjustments, valve cleaning, etc.


  1. How can you prevent a cast iron gate valve from jamming?

Gate valves should be operated regularly, fully opened and closed once every 3-6 months. Also ensure no debris in the pipeline and adequate lubrication. Never force open a jammed gate valve with excessive force.


  1. What is the temperature range for cast iron gate valves?

The usage temperature range for cast iron gate valves is typically -29°C to 220°C. Exceeding this range will accelerate corrosion and wear.


  1. What maintenance is required for cast iron gate valves?

Main maintenance includes: regular re-greasing, inspection/adjustment/replacement of packing, cleaning valve internals, checking bolting, coating maintenance, operation testing, etc.
