AGB combined operating solenoid valves utilize line pressure but don’t require it. Our valves combine the operation of a direct and pilot operated solenoid valve giving you one of the most robust multipurpose valves in the market today. They are ideally suited to applications where there is no line pressure or if you are unsure of the differential pressures. Applications include Glycol lines for craft brewing, water filtration, evaporators and air filtration.

An "assisted lift solenoid valve" is a type of solenoid valve that is designed to open and close with the assistance of a spring or other mechanical means. Unlike traditional direct-acting solenoid valves, which rely solely on the magnetic force generated by the solenoid coil to move the valve's sealing element, an assisted lift solenoid valve uses a combination of electromagnetic force and mechanical force to operate. This design provides certain advantages in specific applications. Here are some key features and applications of assisted lift solenoid valves:
Key Features:
  1. Assisted Lift Mechanism: The main feature of an assisted lift solenoid valve is the inclusion of a spring or other mechanical mechanism that assists in lifting the valve's sealing element (such as a plunger or poppet) when the solenoid is energized.
  2. Reliability: The assisted lift mechanism enhances the reliability of these valves, especially in applications with low-pressure differentials or where the valve needs to overcome some resistance to open.
  3. Quick Response: Like traditional solenoid valves, assisted lift solenoid valves can provide quick response times when the solenoid is energized, allowing for rapid on/off control of fluid flow.
  4. Low Power Consumption: Depending on the design, assisted lift solenoid valves may require lower power consumption compared to direct-acting solenoid valves because the spring assists in opening the valve.
Applications:
  1. Low-Pressure Differential Applications: Assisted lift solenoid valves are well-suited for applications where the pressure differential between the inlet and outlet is relatively low. The spring assists in opening the valve even under low-pressure conditions.
  2. Liquid Dispensing: These valves can be used in liquid dispensing systems, such as in beverage vending machines, where precise control of fluid flow is essential.
  3. Medical and Analytical Instruments: Assisted lift solenoid valves find use in medical equipment and analytical instruments where reliable and precise fluid control is required.
  4. Gas Control: They can be employed in gas control systems where the valve needs to open against the pressure of the gas.
  5. Environmental Control: In environmental control systems, such as air quality monitoring and pollution control, these valves can be used to control the flow of gases or liquids.
It's important to note that the specific design and performance characteristics of assisted lift solenoid valves can vary among manufacturers and models. When selecting a solenoid valve for a particular application, consider factors such as fluid compatibility, pressure and temperature requirements, flow rate, and the need for assisted lift operation based on the system's conditions and requirements.
