Jlab Export is a leading Access Valve Manufacturer,and suppliers in India
An access valve gives a refrigeration line a sealed service port, where gauges can be connected for charging, evacuation and pressure readings. This valve has a 1/4 in SAE male flare port on a copper stem of 1/4 in OD and 4 in length. A spring-assisted poppet core keeps it shut, and the metal cap comes with a core remover.

Practicals for Refrigeration Students
Fitting a service port is a common practical. Students take the core out of the valve and braze the copper stem into a tee or onto a process tube with Brazing Rod. Once the joint is cool, the core and the cap go back on.
The port is then connected to Manifold Gauges For Refrigeration Systems to pressure test the system, and later to evacuate and charge it. Students see that a hose with a core depressor opens the poppet, and that the valve shuts again as soon as the hose comes off.
Frequently Asked Questions
Why take the valve core out before brazing?
Brazing heat can damage the seal on the core. Remove it with the core remover on the cap, braze the stem, let the joint cool and then screw the core back in.
Which hoses fit the 1/4 in SAE flare port?
Standard refrigeration service hoses with 1/4 in SAE flare ends, such as the Refrigerant Hose set. The hose end needs a core depressor so that it opens the valve when it is tightened.
How does the poppet valve core work?
A spring holds the small poppet against its seat, so the port stays closed. When a hose depressor pushes the pin in, the poppet lifts and gas can flow. Take the hose off and the spring closes it again.
How is air cleared from the short tube behind a new valve?
Air is trapped in the short length between a pinch and a newly brazed valve. Connect a vacuum pump through the valve and pull a vacuum on that section before it is opened to the system. Only then release the pinch.
Should the cap always be refitted?
Yes. The cap keeps dirt and moisture out of the core and acts as a second seal against slow leaks. Refit it after every gauge connection.
