INTRODUCTION:
In industrial pipeline systems, valves are indispensable and important components with a wide variety of types and different functions. This article will mainly compare the J-VALVES WCB ELECTRIC ACTUATED FLANGED GATE VALVE with trunnion ball valves, butterfly valves, and globe valves, analyzing their advantages and disadvantages in terms of structural design, operation modes, sealing performance, and applicable scenarios, so as to help users choose the most suitable valve type.
The J-VALVES WCB ELECTRIC ACTUATED FLANGED GATE VALVE is a high-performance electric gate valve, which is widely used in industries such as petroleum, chemical engineering, and electric power. Its main features include:
· Material and Structure: Made of WCB material, it is resistant to high temperature and high pressure and is suitable for media such as steam and oil products.
· Operation Mode: It supports control by an electric actuator, is convenient to operate, and is suitable for remote control scenarios.
· Sealing Performance: The gate and the valve seat are overlay welded with wear-resistant materials, having excellent sealing performance and a long service life.
· Pressure Rating: The nominal pressure can reach PN40, making it suitable for high-pressure working conditions.
TRUNNION BALL VALVES are lightweight valves, mainly used in low-pressure and small-diameter pipelines.
· Structural Features: The ball can achieve opening and closing by rotating 90°, and the structure is simple.
· Applicable Range: They are suitable for small flow regulation of gases, liquids, and steam.
· Sealing Performance: The sealing performance is relatively good, but they are not suitable for high-pressure working conditions.
· Operation Mode: Manual or pneumatic operation is mainly adopted.
BUTTERFLY VALVES are valves with low fluid resistance and are often used for flow regulation.
· Structural Features: The butterfly plate forms a 90° angle with the pipeline, resulting in low fluid resistance.
· Applicable Range: They are suitable for media such as water, sewage, and those containing suspended particles.
· Sealing Performance: The sealing performance is average, but the price is relatively low.
· Operation Mode: Manual, electric, or pneumatic operation is available.
GLOBE VALVES are valves used for cutting off or regulating the flow.
· Structural Features: The fluid resistance is relatively large, and the opening and closing torque is also relatively large.
· Applicable Range: They are suitable for media such as steam, water, and oil products.
· Sealing Performance: The sealing performance is relatively good, but when closing, it is necessary to overcome the resistance of the medium.
· Operation Mode: Manual or electric operation is adopted.
Valve Type | Structural Features | Applicable Range | Sealing Performance | Operation Mode | Pressure Rating | Price |
J-VALVES WCB | Made of cast steel, equipped with an electric actuator, and the sealing surface is overlay welded with wear-resistant materials | High-pressure steam, oil products, etc. | Excellent | Electric | PN40 | Relatively high |
Trunnion Ball Valve | Simple structure, lightweight | Small flow regulation | Relatively good | Manual/Pneumatic | Low pressure | Relatively low |
Butterfly Valve | Low fluid resistance, the butterfly plate rotates 90° | Water, sewage, and media containing suspended particles | Average | Manual/Electric/Pneumatic | Low pressure | Relatively low |
Globe Valve | Relatively large fluid resistance, relatively large opening and closing torque | Steam, water, and oil products | Relatively good | Manual/Electric | Medium pressure | Moderate |
IT CAN BE SEEN FROM THE COMPARISON THAT:
· The J-VALVES WCB ELECTRIC ACTUATED FLANGED GATE VALVE performs best under high-pressure working conditions due to its excellent sealing performance and suitability for high pressure.
· TRUNNION BALL VALVES are suitable for low-pressure and small-flow regulation scenarios. They are easy to operate but have average sealing performance.
· BUTTERFLY VALVES are suitable for scenarios where low fluid resistance is required. They have a relatively low price but average sealing performance.
· GLOBE VALVES are suitable for flow regulation under medium-pressure working conditions, but when closing, it is necessary to overcome relatively large resistance.
Users should make comprehensive considerations according to specific working condition requirements (such as pressure rating, medium type, operation mode, etc.) when choosing valves.
