Customised Gate Valve Features

- Space Efficiency and Fluid Flow

Industrial gate valves open the valve by raising an obstruction (the gate) to allow fluid to pass through. This design takes up very little space in the pipeline and impedes fluid flow very little when fully open.

- Sealing Performance

The surfaces of the gate can be parallel or wedge shaped, with the wedge design providing better sealing performance by applying pressure.

- Operating Mechanism

Gate valves are operated by a stem connected to an actuator such as a handwheel or motor. The stem can be raised or non-raised, providing a visual indication of the valve's open status.

- High Pressure Adaptability

At high pressures, the pressure of the medium may push the gate against the guide, making operation more difficult. Large gate valves may be equipped with a bypass, controlled by a small valve to reduce internal pressure prior to operation.

- Special Purpose Valves

Examples include knife gate valves, which have tapered blade edges for shutting off plastic solids and thick slurries such as paper pulp.

 Customised Gate Valve Specifications

Industrial gate valves can be customized to meet specific industrial applications. Customization options may include valve size, pipe diameter (from 2 inch gate valve to the largest pipe), stem type (rising or non-rising), and whether or not it is equipped with a bypass. Customers can select the most appropriate configuration for their needs to ensure valve performance and reliability under specific conditions.

|

 Customised Materials

Industrial gate valves are available in a wide selection of customized materials, which can be tailored to different working environments and media characteristics. Commonly used materials include cast iron, carbon steel castings, ductile iron, brass, stainless steel, alloy steel and forged steel. These material choices ensure that the valves are able to operate stably under a wide range of temperatures, pressures and chemical properties.

|

 Gate Valve Usage Scenarios

Industrial gate valves are widely used in a variety of industrial applications including, but not limited to, oil and gas transmission, chemical production, water treatment and distribution, and zone separation in ultra-high pressure vacuum chambers. They are particularly well suited for large piping systems that require frequent opening and closing, as well as for operating under high pressure and high temperature conditions. In addition, knife gate valves are useful in industrial processes that handle solid particles and thick slurries.

 FAQs

1.Q: How do gate valves work?

A:Gate valves are primarily used to stop the flow of liquids rather than to regulate flow, which is usually done by a ball valve. When a gate valve is fully open, it allows unobstructed flow, thus creating the least amount of resistance.

2. Q: How is a gate valve constructed?

A:Gate valves are operated by a stem connected to an actuator such as a handwheel or motor. These valves can have rising or non-rising stems, depending on the position of the threads.

3.Q: What is a knife gate valve and what are its characteristics?

A:A knife gate valve is a special valve used to stop the flow of plastic solids and thick slurries (such as paper pulp) by cutting through them. Unlike wedge shaped valves, knife gate valves have a tapered razor blade shaped edge on their lower surface.

4. Q: What are the different types of gate valves?

A:There are several types of gate valves, including wedge gate valves, knife gate valves, straight-through gate valves, parallel sliding gate valves, and parallel extending gate valves, each with its own specific applications and advantages.

5. Q: What are the advantages of electric actuator gate valves?

A: Electric actuators can be customised to suit the specific needs of a gate valve and can be powered by three-phase current, AC or DC. Although the initial cost is high, they provide long service life and require minimal maintenance.
