337,338 series is mainly a stainless steel solenoid valvetailored for commercial coffee machines. lt is divided intotwo categories: 2-Ways and 3-ways. Mainly used in air,water, high temperature steam and other environments.It complies with differentinternational certificationstandards.
Our stainless - steel base plate valve is crafted from high - grade stainless steel, specifically 304 or 316 depending on your needs. 304 stainless steel offers excellent corrosion resistance, making it ideal for regular coffee - making environments where it comes into contact with water, coffee residue, and steam. For more demanding applications, such as in commercial espresso machines where high - temperature and high - pressure steam is prevalent, 316 stainless steel is available. It has enhanced resistance to corrosion from acidic coffee components and can withstand harsher operating conditions. The use of stainless steel not only ensures durability but also meets strict food - grade requirements, guaranteeing that no harmful substances leach into the coffee - making process.
Precise Design for Optimal Function
- Base Plate Mounting: The valve is designed with a base plate for easy and secure installation. The base plate features pre - drilled holes that are compatible with standard coffee machine mounting configurations, whether it's a compact home espresso machine or a large - scale commercial unit. This design allows for quick and hassle - free replacement or initial installation, reducing downtime for maintenance.
- Valve Mechanism: It comes with a reliable valve mechanism, such as a ball valve or diaphragm valve option. The ball valve version provides a straightforward and efficient way to control the flow of liquid or steam. The smooth - moving ball ensures a tight seal when closed, preventing any leakage, and a quick - opening action for seamless operation. Diaphragm valves, on the other hand, are known for their hygienic design. The flexible diaphragm separates the fluid from the mechanical parts of the valve, reducing the risk of contamination. It is also highly responsive to pressure changes, making it suitable for applications where precise flow control is crucial, like in the water supply or waste - water drainage systems of a coffee machine.
- Connection Ports: The valve is equipped with standard - sized connection ports, such as 1/4" NPT (National Pipe Thread), 3/8" BSP (British Standard Pipe), or other commonly used thread types. These ports ensure a leak - free connection to the coffee machine's piping system. Whether it's connecting to the water inlet, steam outlet, or waste - water drain, the compatibility of the connection ports simplifies the integration process.
Versatile Applications in Coffee Machines
- Water Inlet Control: As a water inlet valve, it regulates the flow of fresh water into the coffee machine's boiler or brewing chamber. The precise control offered by the valve ensures that the correct amount of water is introduced for each brew cycle. This is essential for maintaining the consistency of the coffee's taste, as too much or too little water can significantly affect the extraction process.
- Steam and Pressure Regulation: In espresso machines, the valve can be used to control the steam pressure. By adjusting the opening and closing of the valve, baristas can fine - tune the steam output for tasks like milk frothing. Additionally, it acts as a safety valve in some cases, releasing excess pressure to prevent over - pressurization of the boiler, which could lead to damage or safety hazards.
- Waste - Water Drainage: For waste - water drainage, the base plate valve efficiently allows the used coffee grounds and water to be expelled from the machine. Its corrosion - resistant properties are particularly important in this application, as waste water may contain acidic coffee residues that could corrode weaker materials over time. The valve's reliable sealing mechanism prevents any backflow of waste water, maintaining a clean and hygienic coffee - making environment.
Quality Assurance and Compliance
- Manufacturing Standards: Each stainless - steel base plate valve is manufactured in accordance with strict international quality standards. Our production facilities follow ISO 9001 guidelines, ensuring that every valve undergoes rigorous quality control checks during and after production. This includes inspection of the material quality, dimensional accuracy, and functionality testing to guarantee that the valve performs as expected.
- Certifications: The valve is compliant with relevant food - safety certifications, such as 51 for materials in contact with food and beverages. For European markets, it also meets CE (Conformité Européene) requirements, which cover aspects like safety, health, and environmental protection. These certifications give you the confidence that the valve is safe for use in coffee - making equipment and adheres to the highest industry standards.
Easy Maintenance and Long - Term Performance
- Low - Maintenance Design: The simple and robust design of the valve makes maintenance a breeze. The stainless - steel construction resists rust and scale build - up, reducing the need for frequent cleaning. In the rare case of maintenance, the valve's components are easily accessible. For example, if the diaphragm in a diaphragm - type valve needs replacement, it can be quickly removed and replaced without the need for specialized tools or complex disassembly procedures.
- Long Service Life: Thanks to its high - quality materials and precise manufacturing, our stainless - steel base plate valve is built to last. It can withstand thousands of open - close cycles without significant wear and tear, providing you with reliable performance over the long term. This durability not only saves you the cost of frequent replacements but also ensures the continuous and efficient operation of your coffee machine.
