UTMOST eccentric rotary plug control valve has the outstanding advantages of simple structure, small volume, lightweight, strong flow capacity, wide adjustable range, wide service temperature range, small leakage, good stability, low cost, and long service life.

As a professional control valve factory, the sealing form of UTMOST eccentric rotary control valve is hard-seal, which is connected with a pneumatic actuator, matching positioner, solenoid valve, and other accessories to realize proportional adjustment.

Rotary Valve Working Principle

The eccentric rotary valve working principlee is a fan-shaped ball valve with eccentric rotation. The eccentric ball core of eccentric rotary plug control valve is tangent to the valve seat, and when it is opened, the spool is separated from the valve seat. When closed, the spool gradually confects the seat of valve, so that the ball exerts a pressing force on the valve seat. The eccentric rotary valve has a simple flow path and low resistance.

Eccentric Rotary Plug Control Valve Structure Feature

Compared with single seat control valve and double seat valves with the same caliber, eccentric rotary disc valve has a larger flow capacity, but its weight is only about 1/3. The spool and the main shaft only rotate, so the friction force it bears when the switch rotates is very small. The flexible arm of the eccentric rotary valve spool produces small elastic deformation and elastic tension under the thrust of the actuator, which makes the contact between the spool and the valve seat more close and firm, so the leakage of the eccentric rotary control valve is very small. At the same time, the thrust required to close the valve is smaller than that of the ball valve and butterfly valve.

What is the Difference between Eccentric Plug Valve and Butterfly Valve?

An eccentric plug valve uses a rotating plug with an off-center shaft to control flow, providing a tight seal and reducing wear. A butterfly valve uses a rotating disc or "butterfly" to regulate flow, offering quick and easy operation with less sealing capability compared to an eccentric plug valve.

FAQs of Eccentric Rotary Plug Control Valve

QWhat are the main advantages of using eccentric rotary plug control valves?

Tight Shut-Off: The eccentric design ensures a tight seal when closed, minimizing leakage.

Precise Control: Provides accurate flow regulation, making it ideal for applications requiring precise control.

Durability: The camming action reduces wear on the valve components, extending the valve's service life.

Low Maintenance: Requires less maintenance compared to other types of control valves due to its simple and robust design.

QIn which industries are eccentric rotary plug control valves commonly used?

Eccentric rotary plug control valves are used in various industries, including:

Chemical Processing: For controlling the flow of corrosive and hazardous fluids.

Oil and Gas: In pipelines and processing plants for precise flow regulation.

Water Treatment: For managing the flow of water and wastewater.

Power Generation: In steam and condensate systems for efficient flow control.

QWhat is the difference between an eccentric rotary disc valve and a standard globe valve?

Eccentric rotary disc valve: Uses an eccentric, off-center plug that rotates within the valve body to regulate flow, offering precise control and minimizing wear, especially in slurry and high-viscosity applications.

Globe valve: Typically uses a linear motion to control flow. It has a stem and a disc that moves up and down to open or close the valve. Globe valves are generally better for on/off control but may wear faster in throttling applications, especially with abrasive fluids.

QCan eccentric rotary disc valve be used in high-pressure systems?

Yes, the eccentric rotary disc valve is suitable for high-pressure applications. Their design provides tight shutoff and can handle a range of pressures, making them ideal for use in industries like power generation, chemical processing, and oil and gas. However, the valve’s materials and specifications must be chosen based on the specific pressure and temperature conditions of the system.

Globe valve for sale

A globe valve is a valve in which the closing member (valve flap) moves along the centerline of the valve seat. According to this form of movement of the valve flap, the change of  different types of globe valves seat opening is proportional to the stroke of the valve flap. Due to the relatively short opening or closing stroke of the valve stem and the very reliable cut-off function of this type of automated globe valve, and because the change of the valve seat opening is in a king proportional relationship with the stroke of the valve flap, it is ideal for the regulation of the flow. Therefore, this type of valve is ideal for use as a cut-off or regulating and throttling valve.

Globe Valve Characteristics

Globe valve is suitable for cutting off or connecting pipeline media in various working conditions in petroleum, chemical, pharmaceutical, fertilizer, and electric power industries with nominal pressure PN1.6~16.0MPa and working temperature ≤600°℃. Its main structural features are as follows:

The product structure is reasonable, has reliable sealing, excellent globe valve operation performance, beautiful shape.

Co-based hard alloy is overlaid on the sealing surface, with good wear resistance, corrosion resistance, and anti-scuffing performance, and long service life.

The stem is tempered and surface nitride treated, with good corrosion resistance and anti-scuffing.

The nominal pressure 225.0MPa(Class1500) middle cavity adopts a self-tightening seal type structure, the sealing performance is enhanced with the increase of pressure to ensure the sealing performance.

The valve globe type is equipped with an inverted sealing structure for reliable sealing.

The globe valve material of parts and the globe valve sizes of flange and butt welding end can be reasonably matched according to the actual working condition or user requirements to meet various engineering needs.

Double Eccentric Butterfly Valve Features

The double offset butterfly valve plate cannot be separated from the sealing surface near the upper and lower ends of the valve plate in the range of 0-10°, and it is still in a sliding friction state. At this time, the torque is large, which may easily cause scratches and bites in this area. This can cause seal leakage. From the structural analysis, the double eccentric is a unidirectional butterfly valve. This double eccentric butterfly valve from china is mainly suitable for the drainage of water plants, power plants, steel smelting, chemical engineering, water source engineering, environmental facility construction, and other systems, especially suitable for water pipelines, as regulating and intercepting equipment. Compared with the centerline butterfly valve, the double eccentric butterfly valve china is more resistant to high pressure, has a longer life, and has good stability. Compared with other valves such as 2 way globe valve, the larger the caliber, the lighter the material, and the lower the cost.
