I was wondering what the purpose of a slide check was.
Thanks in advance

How a Slide-Check Valve Works
A slide-check valve is a critical piece of gear when you’re using a remote. The valve makes the job of disconnecting the marker from the remote line easy and safe.
As shown in the diagram, a slide-check valve is simply a tube that is blind-drilled on both ends. Two ports are drilled into the blind passages. The slide has two o-rings for seals and moves back and forth to connect the ports. Gas pressure helps the o-rings to seal.
When the slide is forward, the entire line, from the tank to the marker’s valve chamber is pressurized (see Fig. 1.) The blue color depicts the high-pressure gas. In the Forward Position, the marker is ready to fire.
When the slide is back, there is no pressure in the line between the marker and the slide-check. In the Back Position, the marker can be removed from the remote, without de-pressurizing the entire line or having to turn off the tank (see Fig. 2.) The line between the tank and the slide-check remains at tank pressure as depicted by the blue color.
Hope that explains it some for ya. :)
