PVC Electric Ball Valve with Plastic Double Ferrules, PPH Material, Small Size, Acid & Alkali Corrosion-Resistant for Industrial Wastewater Discharge - 2-Way and 3-Way Valves

PVC and PPH Materials: The valve is made of PVC (Polyvinyl Chloride) and PPH (Polypropylene Homopolymer). PVC is a well - known plastic material that offers good chemical resistance and durability at a relatively low cost. PPH, on the other hand, is a high - performance polypropylene material with excellent resistance to acids and alkalis. The combination of these materials makes the valve suitable for handling industrial wastewater, which often contains corrosive substances.

Double Ferrule Design: The plastic double ferrules provide a reliable connection between the valve and the piping system. Ferrules work by compressing onto the pipe and the valve body to create a tight seal. This design ensures a leak - free connection and also allows for easy installation and removal of the valve, which is beneficial for maintenance and replacement purposes.

Small Size: The small - sized nature of the valve makes it suitable for applications where space is limited. It can be easily integrated into compact industrial wastewater discharge systems without taking up too much room.

2 - Way Valves: These valves have two ports - an inlet and an outlet. They are used to simply control the on - off flow of wastewater. When the valve is open, the wastewater can pass through from the inlet to the outlet, and when it's closed, the flow is blocked.

3 - Way Valves: The 3 - way valves have three ports and offer more complex flow control options. They can be used to split the wastewater flow into two different directions or to combine flows from two sources into one. This flexibility in flow control is useful in industrial settings where wastewater may need to be diverted to different treatment processes or storage tanks.

Inside the valve, there is a ball with a hole or opening. In the case of a 2 - way valve, when the ball is rotated so that the hole aligns with the inlet and outlet ports, the wastewater can flow through. When the ball is rotated to a position where the hole is not in line with the ports, the valve is closed, and the flow is stopped.

For 3 - way valves, the position of the ball determines the flow direction. Depending on how the ball is rotated, the wastewater can be directed from the inlet to either of the two outlets (split flow), or from two inlets to a single outlet (combined flow).

The valve is equipped with an electric actuator. When a control signal is received, the actuator's motor rotates, which is then translated into the rotation of the ball through a gear mechanism. The electric actuation allows for remote or automated control of the valve. This is beneficial in industrial wastewater discharge systems, where the flow of wastewater may need to be controlled based on factors such as the level of the wastewater in a tank, the operating hours of a treatment process, or the need to respond to emergencies.

In chemical plants, where the wastewater often contains a variety of acids, alkalis, and other chemicals, these valves can be used to control the flow of wastewater from different production processes to the treatment facility. The acid and alkali - corrosion - resistant properties of the valve ensure its durability in such harsh chemical environments.

In the food and beverage industry, the valves can be used to manage the wastewater generated during processing, such as from washing fruits and vegetables or from cleaning equipment. The small - sized valves are suitable for the relatively smaller - scale wastewater systems in these facilities, and the double ferrule connections make installation and maintenance convenient.

Textile factories produce wastewater that contains dyes and other chemicals. These valves can be used to direct the wastewater to appropriate treatment or disposal areas. The 3 - way valves can be particularly useful for separating different types of wastewater (e.g., dye - containing wastewater from general wash water) for more efficient treatment.

The use of PVC and PPH materials provides excellent resistance to acids and alkalis, which is crucial for handling industrial wastewater. This resistance helps to extend the life of the valve and reduces the need for frequent replacement, saving costs in the long run.

The availability of 2 - way and 3 - way valves offers flexibility in managing the flow of wastewater. The ability to split or combine flows allows for more efficient operation of wastewater discharge systems and better integration with different treatment processes.

The plastic double ferrule design simplifies the installation process. The valve can be easily connected to the piping system without the need for complex welding or threading. Additionally, the small size makes it easier to access and maintain, and if a valve needs to be replaced, the double ferrule connections allow for quick removal and replacement.

When installing the valve, it's important to ensure that the double ferrules are properly tightened onto the pipes. The pipes should be clean and free of debris to ensure a good seal. The electric actuator should be wired according to the manufacturer's instructions, and proper grounding should be provided to prevent electrical hazards.

Regular maintenance includes checking the seals around the ferrules and the ball valve for any signs of leakage. The ball and the interior of the valve body should be inspected for damage or debris buildup. The electric actuator's performance should be tested periodically to ensure that it responds correctly to control signals. If any problems are detected, such as a leaking seal or a malfunctioning actuator, they should be addressed promptly to maintain the proper functioning of the wastewater discharge system.
