Alpha Series Solenoid Operated Pneumatic Valve, 4-way 2-position, Spring Return, 1/4 NPT (Side) Ports, 50 Flow Rating

Description & Features

The compact design of this valve ensures efficient space utilization, while the ISO identification on ports aids in reliable installation. Operating within a pressure range from vacuum to 150 PSI, the valve offers a high cycle rate of 600 cycles per minute, making it suitable for stand-alone or remote applications.

Constructed with a zinc body and urethane/Vitonreg; bonded precision ground spools, it guarantees durability and prolonged service life. The 1/4 NPT (side) ports and high flow capability (50 SCFM) are based on 100 PSIG input and 85 PSIG output.

This directional solenoid operated valve features a 4-way 2-position spool action with a spring return mechanism and requires a minimum shift pressure of 50 PSI for single solenoid or 20 PSI for double solenoid application. The valve does not necessitate lubrication and is optimized for fast signal response times (20ms Double Solenoid, 22ms Single Solenoid Energize, 27ms Single Solenoid De-energize).

For enhanced versatility, optional external solenoid supply plug kits are available, facilitating use in vacuum and low-pressure applications.

Recommended filtration for the valve is 40 microns, with an operational temperature range spanning from 0deg;F to 180deg;F.

Question by: Harvey A on Aug 21, 2025, 6:16 AM

What kind of flow rating does this valve have?

Answer by: Customer Support on Aug 22, 2025, 10:58 AM

This valve is rated for a 50 SCFM flow rating, based on a 100 PSIG input and 85 PSIG output.

runs about 600 cycles a minute sound right for this valve? trying to figure out if it'll keep up on a pretty fast automated line

Answer by: Customer Support on Jul 16, 2025, 6:26 AM

Yeah, 600 cycles per minute is exactly what this valve is rated for, so it should hold its own on a high-speed line. Response time comes in at 22ms when energized and 27ms on de-energize for the single solenoid setup, which is quick enough for most automated applications running at that pace. Just make sure your supply pressure stays in range and your air is filtered to 40 micron or better, and you won't be leaving any performance on the table.

trying to run this valve on a vacuum setup, is that even in its range?

Answer by: Customer Support on Feb 9, 2026, 7:08 AM

For operating limits, it is rated to work from vacuum up to 150 PSI. There is also an optional external solenoid supply plug kit (119306) that allows the valve to be used in vacuum and low pressure applications.

Question by: Rhonda M on Nov 18, 2025, 10:12 AM

trying to tuck this valve in a tight spot, are the ports on the side and are they 1/4 npt?

Answer by: Customer Support on Nov 19, 2025, 12:59 PM

For mounting in cramped panels or small manifolds, it uses 1/4 NPT ports located on the side, and the ports have ISO identification to help keep the connections straight during install.

Question by: Todd B on Oct 25, 2025, 7:49 AM

Can this valve handle dirty air, or do I need to run a filter?

Answer by: Customer Support on Oct 27, 2025, 7:46 AM

A 40-micron filter is recommended to keep this valve running smoothly.
