NORGREN V61B313A-A218J Two Position Three-way Pilot Solenoid Valve

Technical Details

Product Description:

This series of solenoid valves utilizes a pilot-operated mechanism, wherein the pilot valve governs the movement of the main spool. The pilot valve is actuated by the solenoid coil, while the main spool responds to the pressure differential of the medium. Such a design enables a low-power solenoid coil to manage the opening and closing of large flow volumes, thereby improving energy efficiency and making it well-suited for high-pressure applications.

The valve is designed to be normally open by default. This means that when the power is off, the valve remains open, allowing fluid to pass through. When the solenoid coil is energized, it actuates the valve to close, stopping the flow of the medium. This normally open feature is ideal for safety-critical systems that require continuous medium flow during power loss, such as cooling circuits or emergency venting setups.

Featuring a single solenoid control, the valve toggles between open and closed positions by energizing or de-energizing just one solenoid coil. Upon de-energization, the valve automatically reverts to its normally open state through the force of a spring or the medium pressure. This mechanism ensures straightforward and dependable operation.

Thanks to its pilot-operated framework and an optimized flow path design, this valve series provides outstanding flow capacity. Depending on the specific model, flow rates range from 610 liters per minute up to 2600 liters per minute, catering to a wide spectrum of applications from moderate to large flow requirements.

These valves typically operate within a pressure range of 0.2 MPa to 1.0 MPa (2 to 10 bar), with certain models capable of handling pressures as high as 1.6 MPa (16 bar). It is important to note that pilot-operated solenoid valves generally require a minimum pressure differential—usually above 0.2 to 0.3 bar—for correct functioning.

The valve body is constructed from die-cast aluminum alloy or aluminum extrusion, which provides a lightweight yet robust and corrosion-resistant structure. The spool and sleeve come in either metal-sealed (designed for long service life) or soft-sealed (optimized for high flow) variants. Sealing materials include NBR or FKM, suitable for compressed air and a variety of other media.

The solenoid coil is engineered for low power usage, with some configurations consuming as little as 1 to 2 watts, contributing significantly to energy savings. The valve typically has an IP65 protection rating, ensuring it is dust-tight and resistant to water jets, making it appropriate for deployment in humid or dusty industrial environments.

A manual override is integrated as a standard feature, often provided as either a push-button or a twist-lock knob. This capability facilitates equipment commissioning, maintenance tasks, and emergency manual operation without dependence on electrical input signals.

The valve ports commonly utilize British pipe threads such as G1/4, G3/8, or G1/2, adhering to international standards to ensure seamless compatibility with various pneumatic components. Installation options include both inline piping and sub-base mounting, offering flexibility to suit different system integration requirements.

Applications:

These valves are extensively used in various automated assembly lines, material handling systems, and packaging machinery. They primarily control single-acting cylinders to perform tasks such as clamping, positioning, and pushing, effectively supporting operations that demand high-frequency and highly reliable control mechanisms.

The 3/2-way solenoid valve is a standard solution for managing single-acting pneumatic actuators, including single-acting cylinders, diaphragm valves, and pneumatic grippers. A normally open (NO) design is particularly advantageous for safety interlock scenarios, allowing the valve to automatically open or close during power outages, which is critical in emergency venting systems.

In applications that require periodic purging or pressure relief, these valves regulate the on/off flow of compressed air. They are essential components in systems such as filter blowback, surface dust removal devices, and safety relief circuits for air receiver tanks.

These valves find wide use in packaging equipment including filling machines, sealing machines, labeling machines, and blow molding machines. By controlling the rapid motions of pneumatic actuators, they help maintain production cycle times and ensure packaging accuracy.

On automotive assembly lines, these valves are employed in welding fixtures, painting devices, assembly stations, and parts processing machinery. They control pneumatic tooling and auxiliary equipment, boasting features like oil resistance, vibration tolerance, and extended service life.

Designed for pneumatic control systems in food processing machinery, these valves are used in processes such as blow molding, filling, and sealing. The selection of sealing materials and lubrication complies with food-grade standards, ensuring hygiene and safety throughout production.

In environmental protection and energy sectors, these valves manage pneumatic control systems within thermal power plants, wastewater treatment facilities, and exhaust gas treatment units. They operate pneumatic control valves and on/off valves to enable automated process control and remote operation.

Certain valve models are optimized for a wide operating temperature range, from –10°C up to +50°C or beyond. In low-temperature environments, dry air is recommended to avoid freezing issues. For areas requiring explosion-proof solutions, optional explosion-proof coils are available to conform to safety regulations.
