Resilient seated gate valves with flange end connections are a common type of industrial valve constructed primarily of ductile iron. They utilize a non-metallic resilient sealing mechanism between the gate and valve seat to achieve tight shutoff. Some key features of this type of valve are:

• The ductile iron body provides good mechanical strength and pressure handling capabilities for use in medium and low pressure piping systems.
• The resilient seat seal delivers low leak rates and good shutoff even under low pressure differential conditions.
• The flange end connections allow easy installation into piping systems and simplify maintenance and removal. Flange faces are precision machined to mate tightly with pipes.
• The gate design provides straightforward operation, with the gate position controlled manually by a handwheel or automatically with electric actuators to regulate fluid flow.
• Compared to metal seated gates, the soft seat seals are less restrictive on fluid composition and offer longer service life.
• These valves feature convenient maintenance, replaceable parts, reliable operation, and economical cost, making them a practical control component for piping networks.

Some important points are to regularly inspect the resilient seal surface and replace if needed, maintain proper flange bolt tightness, and check for smooth gate movement. With proper sizing and care, resilient seated flange end ductile iron gate valves can provide excellent fluid control for pipeline systems.

Packing Details

• Valves should be packaged individually in sturdy boxes filled with cushioning material to prevent damage during shipping and handling.
• Smaller valves may be packed in corrugated cardboard boxes with foam or paper cushioning. Larger valves may use wooden crates.
• Flange faces should have protective covers made of cardboard, plastic, or wood to prevent scratching or impact damage to the sealing surfaces.
• Valve ends should be capped or plugged with plastic covers to keep out dirt and debris during shipping.
• Stem threads should be greased and a plastic cap placed on the stem end. The handwheel can be removed and packaged separately.
• Any accessories like gaskets, bolts, or manual handwheels should be packed alongside the main valve or in separate boxes.
• A packing list should be included detailing all valve components and accessories in the shipment.
• Instruction manuals for installation, operation and maintenance should be provided.
• Valves and crates should be properly labeled with manufacturer name, valve model and size, pressure rating, serial numbers, and any special handling instructions.
• For international shipments, ISPM-15 compliant wood packaging may be required.
• Desiccant bags may be included to control humidity and prevent corrosion during transit and storage.
• Upon receiving, valves should be immediately inspected for any damage during shipment.

FAQ

1. What is a PN16 electric resilient seated flange end ductile iron gate valve?

A PN16 electric resilient seated flange end ductile iron gate valve is a type of valve that is designed to control the flow of fluids (liquids or gases) in a pipeline. It is made of ductile iron, which is a type of cast iron that offers high strength and durability. The valve has a flange end connection, which allows for easy installation and removal. It is classified as PN16, which means it is designed to withstand a maximum pressure of 16 bar.

2. What are the advantages of using a resilient seated gate valve?

Resilient seated gate valves offer several advantages over other types of valves. Firstly, they provide a tight seal, preventing any leakage of fluids. This makes them suitable for applications where a high level of sealing is required. Secondly, they have a low operating torque, which means they can be operated easily and quickly. Additionally, resilient seated gate valves are resistant to corrosion, making them suitable for use in various environments.

3. What is the purpose of an electric actuator in a gate valve?

An electric actuator is used to automate the operation of a gate valve. It is an electromechanical device that converts electrical energy into mechanical energy, allowing the valve to be opened or closed remotely. Electric actuators offer several advantages, such as precise control, fast response time, and the ability to integrate with control systems for remote monitoring and control.

4. How does a resilient seated gate valve work?

A resilient seated gate valve works by using a gate or disc that moves up and down to control the flow of fluids. When the valve is open, the gate is lifted, allowing the fluid to flow through the valve. When the valve is closed, the gate is lowered, blocking the flow of fluid. The resilient seat on the gate provides a tight seal against the valve body, preventing any leakage.

5. What applications are PN16 electric resilient seated flange end ductile iron gate valves suitable for?

PN16 electric resilient seated flange end ductile iron gate valves are suitable for a wide range of applications, including water distribution systems, wastewater treatment plants, industrial processes, and HVAC systems. They can be used for both on/off and throttling applications, making them versatile in various industries.

6. What are the maintenance requirements for PN16 electric resilient seated flange end ductile iron gate valves?

Maintenance requirements for PN16 electric resilient seated flange end ductile iron gate valves are generally low. However, regular inspection and cleaning of the valve components are recommended to ensure proper functioning. Lubrication of the stem and other moving parts may also be required periodically. It is important to follow the manufacturer's guidelines and recommendations for maintenance to prolong the lifespan of the valve.

7. Can PN16 electric resilient seated flange end ductile iron gate valves be used for high-temperature applications?

PN16 electric resilient seated flange end ductile iron gate valves are generally not recommended for high-temperature applications. Ductile iron has a limited temperature range, and prolonged exposure to high temperatures can cause the valve to deform or fail. For high-temperature applications, valves made of materials such as stainless steel or cast steel are more suitable.
