3V Series 3-Way Pneumatic Solenoid Valves

Features & Key Specifications

Features & Key Specifications of Our 3V Series:

Optimized for Single-Acting Cylinders:
As a 3-port, 2-position (3/2 way) valve, it is the standard choice for controlling single-acting pneumatic cylinders, providing the necessary pressure and exhaust paths.

Rapid & High-Frequency Performance:
With a swift activation time of just 0.05 seconds and a maximum frequency of 5 Hz, these valves are ideal for applications requiring fast and repetitive switching.

NC and NO Functions Available:
To suit different safety and logic requirements, this series is available in both Normally Closed (NC) configuration (air passes when energized) and Normally Open (NO) configuration (air is blocked when energized).

Full Range of Sizes and Ports:
Available in multiple body sizes (100 to 400 series) with port sizes ranging from M5 up to 1/2", ensuring the perfect flow rate for your specific application.

Global Electrical & Thread Compatibility:
We offer a complete range of coil voltages (e.g., 24V DC, 110V AC) with DIN or flying lead options. To meet global requirements, NPT, BSPP (G), and BSPT (P) thread types are available.

Robust & Reliable Design:
Featuring a durable aluminum alloy body and IP65 rated coils with Class F insulation, these valves are built to withstand typical industrial environments.

Application Fields

Common Applications:

Actuator Control: Primary control for single-acting (spring-return) cylinders in clamping, sorting, and ejection mechanisms.

Pneumatic Piloting: Used as a pilot signal valve to actuate larger air-piloted valves (like our 4A series).

Air-Blow & Cleaning: Perfect for controlling intermittent air blasts in parts cleaning, drying, or static elimination systems.

Diverter/Selector Valve: Can be used to select between two different air paths or pressure sources.

Vacuum Control: Suitable for use on the pilot or vent side of vacuum generator (ejector) systems.

Technical & Selection Guide

Understanding 3-Way Valve Technology

What does "3-Way" (3/2) mean?
A 3-way valve has three working ports: an Inlet (P), an Outlet (A), and an Exhaust (R). It switches between two positions: connecting the Inlet to the Outlet, or connecting the Outlet to the Exhaust.

Choosing Between Normally Closed (NC) and Normally Open (NO):

Normally Closed (NC): The most common. The valve is closed at rest and opens when energized. Choose this for actions that should only happen when a signal is present.

Normally Open (NO): The valve is open at rest and closes when energized. Choose this for safety circuits where you need flow to be present in a power-off state.

Direct-Acting vs. Pilot-Operated:

Direct-Acting: The solenoid directly opens the valve. This is very fast and works from 0 pressure, typically used for smaller port sizes (e.g., 3V1 series, M5/1/8").

Pilot-Operated: A small internal pilot helps open the main valve. This allows for higher flow with a smaller coil, but requires a minimum operating pressure. This is the common design for larger valves (e.g., 3V200 series, 1/4" and up).

FAQ

Frequently Asked Questions

Q: Can I use a 3-way valve to control a double-acting cylinder?
A: No. A double-acting cylinder requires a 5-way valve (like our 4V series) to control both extend and retract strokes. A 3-way valve is designed for single-acting cylinders.

Q: What is the difference between your 3V series and 4V series?
A: The function. The 3V series is a 3-way valve for single-acting cylinders or on-off control. The 4V series is a 5-way valve designed for double-acting cylinders.

Q: What does the model number 3V210-08 mean?
A: This is an industry-standard code. '3V' is the series, '2' is the body size, '10' means single solenoid, and '-08' specifies the port size (G1/4"). Our datasheets provide a full breakdown.
