About the Airtac S3PP Convex Head Push-button Mechanical Valve S3PP08R
Built on an aluminum-alloy body, the AirTAC S3PP08R is a 3/2-way mechanical valve with PT1/4 ports and the extended push button head (PP) in red. It is worked by hand, as a simple control for an air circuit at the machine or on a panel. At the PT1/4 port the effective area is 12.0 mm2 (Cv 0.67). The catalog gives a spool travel of 2.4-4.0 mm and a head travel of 3.8-5.4 mm.
It is a poppet valve, so it seals tightly and switches cleanly. It runs on air filtered to 40 um from 0 to 1.0 MPa (0-145 psi), with 1.5 MPa (215 psi) proof pressure, at -20 to +70 C. No lubrication is needed; once the valve has been lubricated, keep lubricating it with ISO VG32 oil. The ports are PT thread, the standard version.

How to choose
This code uses the 1/4 port (12.0 mm2, Cv 0.67); the same PP head also comes with M5 (Cv 0.14) and 1/8 (06, Cv 0.45). A larger port passes more air when the valve drives a cylinder or a long pilot line directly. The color letter after the port is R (red) here; S3PP08G green and S3PP08B black are the other colors of this head. For BSPP or NPT threads order S3PP08RG or S3PP08RT. Other hand-operated heads: long handle (C), short handle (D), rocker lever (Y), mushroom push button (PM), flush push button (PF), turn-release latching button (PL) and selector switch (HS).
Applications
Start button on a panel
A push button starts an air cycle at the operator panel.
Air-only control desks
Air buttons work where electric switches are not wanted, with no wiring in the panel. The PT1/4 port gives Cv 0.67.
Two-hand and sequence circuits
Sends a pilot signal into an air logic circuit when pressed.
FAQ
What are the key figures of the S3PP08R?
3/2-way mechanical valve, extended push button head (PP), red; PT1/4 ports, effective area 12.0 mm2 (Cv 0.67); 0 to 1.0 MPa (0-145 psi), proof 1.5 MPa (215 psi); -20 to +70 C; air filtered to 40 um; aluminum-alloy body; spool travel 2.4-4.0 mm.
What does the R in S3PP08R mean?
It is the color letter of the extended push button: R = red. Only the push-button and selector heads take a color letter (R red, G green, B black).
