Solenoid valve replacement project Step 1: Determine the voltage. AC for alternating current, DC for direct current. Step 2: Determine the water pressure. If there could also be water strain (such as faucet water and pump water) andthe pressure differ is 0, prefer the water inlet valve; No water pressure (for example, zero m excessive water tank) Pressure range: 0-0, select the water discharge valve. Step 3: Determine the water temperature. Choose plastic valve at room temperature, copper valve or stainless-steel valve at high temperature. Step 4: Determine the caliber. Valve body inlet and outlet diameter size in conserving with the actual sample or establish requirements. Step 5: Special requirements. Please take the initiative to consult guest service, through negotiation to arrive a solution. General InstructionsRoutine directions are a question that almost each guest asks1. What is a pressure valve (inlet valve) and what is a pressureless valve (drain valve)?The stress valve is also referred to because the inlet valve, and the non-pressure valve is also known as the drain valve. If there could also be pressure, it capability there's water pressure. If there's no pressure, it means no water pressure. The stress valve is suitable for 0~0 water pressure, no pressure valve is suitable for 0-0(0)pa water pressure, if the solenoid valve is never utilized in the traditional strain range, it is going to not paintings normally! The container is used for water discharge without pressure. However, because the water stress modifications and the scale of the water tank should not absolute, it is more clean to say that the water output is sprayed with pressure, and the visual display unit circulate is with out pressure. Because we can&;t hold close the categorical use environment of the parent, we solely provide the reference standard, and we have to like it via ourselves. In particular, please use AC220V pressure-free valve with caution, this one may have jitter and noise. Diaphragm solenoid valve AC pressure-free form has this undertaking now, and it cannot be solved for the time being. How to realize automatic control?The product is awfully simple. When it is powered on and off, it will likely be related and disconnected. If you prefer to note automation by means of method of PLC or different controller control, please give you the chance yourself! Commonly used, it may be controlled by way of temperature control, time control, delicate control, and liquid level. And diversified controllers are geared up with solenoid valves to attain diversified functions. What is usually open and typically closed?The solenoid valve is energized and water-connected, and the power-off water is lower off. It is a assuredly closed type, which is extra generally used;The solenoid valve is energized to chop off the water, and the water is carry to an finish when the flexibility is off. It is rarely used for the often open type. Please buy consistent with your individual needs. Is the coil hot?The solenoid valve is a pure copper coil. It is common for long-term operation to generate heat. Generally, it may be continuously energized for decades in an atmosphere the place the ambient temperature is less than 30 degrees. It is usually recommended that the ambient temperature is larger than 30 degrees. . 12V24V220V Inlet Valve Drain Valve Solenoid Valve
