ERA COMPACT BALL VALVE Ⅱ SINGLE UNION BALL VALVE Ⅱ TRUE UNION BALL VALVE

Product:

COMPACT BALL VALVE : Compact ball valve is a commonly used control valve, which mainly consists of components such as valve body, handle, and valve ball. The valve body is equipped with inlet and outlet pipelines, and there is a spherical valve core inside. The handle is used to control the movement of the valve core. When the handle rotates, the valve core also rotates, thereby controlling the direction and flow rate of fluid in the valve.

ⅡSINGLE UNION BALL VALVE : Adopting a Type II structural design, it has a single-sided control function and can be used for medium pressure and flow applications.

ⅡTRUE UNION BALL VALVE : It also adopts a Type II structural design, but has a dual sided ball valve function, suitable for higher pressure and flow situations.

These valves are commonly used to regulate flow in liquid and gas pipelines.

The term "ⅡSINGLE UNION BALL VALVE" refers to a valve with only one port, allowing fluid to pass through in one direction and close off in the other.

A "ⅡTRUE UNION BALL VALVE" has two ports, enabling control of fluid flow in both directions and providing enhanced control performance.

Features:

Compared with other ball valves, the advantage of the compact ball valve lies in its uncomplicated structure and easy operation, making it suitable for basic fluid control tasks.The installation process is straightforward, the construction is uncomplicated, and maintenance is hassle-free.

The Ⅱ single union ball valve is suitable for situations where only one fluid needs to be controlled, such as water flow or air flow, without the need to control the direction change.

The Ⅱ true union ball valve is suitable for scenarios wheretwo fluids need to be controlled at the same time, suitable for applications requiring bidirectional flow control and prevention of reverse flow.

Comparison:

In the material of O-Ring, Other factories use NBR, which has several drawbacks: it has poor cold resistance and ozone resistance, lower strength and elasticity, poor acid resistance, and poor electrical insulation properties. Additionally, it also has poor resistance to polar solvents.

ERA uses EPDM , which has excellent electrical insulation, chemical resistance, and impact elasticity. It is also resistant to acid and alkali, has a low specific gravity, and is superior in terms of ozone resistance, UV resistance, weather resistance, and aging resistance, ranking at the top among general-purpose rubbers.

SPEARS is known for its high-quality and very stable products, focusing on high-end distributors in the market and occupying the high-end brand market segment. However, its products are primarily aimed at the industrial market category, with a low coverage rate in the consumer-grade market; as a result, they are considered to have a lower cost-performance ratio.

TIGRE has the broadest brand influence and high market share, covering various fields such as large supermarkets, retail, wholesale, and distributors. However, the product quality is average, and its product line is relatively weak in terms of pipe fittings, with prices on the higher side.

Zhejiang Xier valve products complete, low price. Strong development ability, flexible market policy, general quality, general production capacity.

ERA has a broad influence and market recognition. With 9 major production bases across the country, it covers most regions of China, forming a strong production and supply capability. Moreover, the brand quality is excellent.

Advantages of plastic ball valves over traditional copper or iron ball valves

(1)Good hygienic performance. No precipitation of heavy metals. It’s safer and healthier to use.

(2)Good corrosion resistance. The corrosion resistance of plastic valves is better than cast iron valves, steel valves, copper valves and stainless steel valves.

(3)More Light weight. Plastic valves are lightweight, about 1/3 of the valve for the metal. Therefore, plastic valves are easier to install and can reduce the installation load of the pipeline. In addition, the light weight can reduce transportation costs and installation costs.

(4)Longer service life. The service life of plastic valves is not less than 25 years, some of the structure of the valve can be maintenance-free.

(5)Smooth inner wall. The inner wall is smoother than valves which are made of metal and less prone to scaling. In the seasonal use of the system, they will not be adsorbed in the valve sealing parts because of some substances in the transport

medium, and affect the opening and closing operation when the valve is used again.

(6) More cost-effective. Relative to metal valves, plastic valves cost-effective, giving the user an increase in the choice of varieties of comparison.

The two valves in the figure were installed in the water pipeline copper products, the left figure is a copper ball valve, the right figure is a copper angle valve, it can be seen that the corrosion resistance of metal valves and resistance to adsorption performance relative to the plastic valves are relatively weak, cast iron valves are even more so.
