FAQ

What is the function of a 3/2-way valve like the S/511H?

A 3/2-way valve has three ports and two positions. In its default state (normally closed), it blocks air from the inlet (port 1) and vents the outlet (port 2) to the exhaust (port 3). When actuated, it connects the inlet to the outlet, pressurizing the connected device, and blocks the exhaust. This is ideal for controlling single-acting pneumatic cylinders.

Can this valve be used for vacuum applications?

While designed for positive pressure, many simple slide valves like the S/511H can function in light vacuum applications. However, for dedicated vacuum systems, it is crucial to consult the manufacturer’s datasheet to confirm its suitability and sealing performance under negative pressure.

What are the typical port sizes for the Norgren S/511 series?

The Norgren S/511 series was available in a range of standard BSPP (G) thread sizes, typically from G1/8 inch to G1/2 inch, to accommodate different flow requirements in pneumatic systems.
