NORGREN V61 Series 3/2 NC Valve, Pilot Actuated, Single Solenoid, Long Service Life – Model A313J

Product Description:

This series of solenoid valves utilizes a pilot-operated principle, where the pilot valve governs the main spool’s movement. The solenoid coil energizes the pilot valve, and the main spool is actuated through the pressure difference of the medium. Such a design enables a low-power solenoid coil to control large flow rates efficiently, making it ideal for applications requiring higher pressures while optimizing energy consumption.

The valve is designed to be normally open by default. In its de-energized state, the valve remains open, permitting the flow of the medium. Once energized, the solenoid coil activates to close the valve, stopping the flow. This normally open configuration is particularly useful for safety-critical scenarios, such as cooling systems or emergency venting, where uninterrupted medium flow is essential during power failures.

Featuring a single solenoid control, the valve switches between open and closed positions by simply energizing or de-energizing one solenoid coil. When power is removed, the valve automatically reverts to its normally open state, aided by spring force or medium pressure, ensuring straightforward and reliable operation.

Thanks to the pilot-operated structure combined with an optimized flow path, these valves provide excellent flow capacity. Depending on the specific model, flow rates range from 610 L/min up to 2600 L/min, catering to a wide range of applications from medium to large flow requirements.

The valves typically operate within a pressure range of 0.2 MPa to 1.0 MPa (2 to 10 bar), with some variants capable of handling pressures as high as 1.6 MPa (16 bar). It is important to maintain a minimum pressure differential, usually above 0.2 to 0.3 bar, to ensure proper pilot operation.

The valve body is constructed from die-cast aluminum alloy or aluminum extrusion, offering a balance of lightweight design, strength, and corrosion resistance. The spool and sleeve can be configured with either metal seals for extended durability or soft seals for enhanced flow performance. Seals are made from materials such as NBR or FKM, making them compatible with compressed air and various other media.

The solenoid coil is designed for low power usage, with some models requiring as little as 1 to 2 watts, significantly reducing energy costs. Additionally, the valves have an IP65 protection rating, ensuring they are dust-tight and protected against water jets, making them suitable for use in humid or dusty industrial settings.

Equipped with a manual override feature, commonly available as a push-button or a twist-lock knob, the valve allows for manual control during commissioning, maintenance, or emergency situations without relying on electrical signals.

The valves come with port threads typically sized at G1/4, G3/8, or G1/2 British pipe threads, adhering to international standards for easy compatibility with a variety of pneumatic components. They support both inline piping and sub-base mounting configurations, providing flexibility to meet diverse system installation needs.

Applications:

These systems are extensively utilized across a variety of automated assembly lines, material handling units, and packaging machinery. Their primary function is to manage single-acting cylinders performing tasks such as clamping, positioning, and pushing. They are engineered to meet the stringent requirements of high-frequency operations and reliable control under demanding industrial conditions.

A 3/2-way solenoid valve serves as the fundamental component for managing single-acting pneumatic actuators, including single-acting cylinders, diaphragm valves, and pneumatic grippers. Valves with a normally open (NO) configuration are particularly advantageous in safety interlock scenarios. They ensure automatic opening or closing in the event of power failure, which is essential for emergency venting and safeguard mechanisms.

In processes that require regular purging or pressure relief, these valves regulate the on/off flow of compressed air efficiently. They are crucial in systems such as filter blowback, dust removal from surfaces, and safety relief circuits designed for air receiver tanks, helping maintain operational integrity and safety.

These valves are widely found in packaging equipment, including filling machines, sealing devices, labeling units, and blow molding apparatus. Their role is to control the swift operation of pneumatic actuators, thereby ensuring optimal production cycle times as well as high precision in packaging activities.

In automotive manufacturing, these components are essential for controlling pneumatic tools within welding fixtures, painting machinery, assembly lines, and parts processing equipment. The valves are designed to withstand oil exposure, resist vibrations, and provide a long service life, meeting the rigorous demands of automotive production environments.

The valves are suitable for integration into pneumatic systems used in food processing equipment, such as blow molding, filling, and sealing machines. Careful selection of sealing materials and lubrication methods that comply with food-grade standards is vital to ensure production safety and maintain hygienic conditions throughout the manufacturing process.

These valves are implemented in valve control systems for various environmental protection facilities, including thermal power plants, wastewater treatment plants, and exhaust gas treatment setups. They enable automated process control and facilitate remote operation by managing pneumatic control valves and on/off valves effectively.

Certain valve models are designed to operate reliably across wide temperature ranges, for example from –10°C up to +50°C or beyond. For low-temperature scenarios, the use of dry air is recommended to prevent freezing issues. Additionally, for locations with explosion-proof requirements, optional explosion-proof coil variants are available to comply with safety regulations.
