No. 210 Series MGM Relief Valves are positive pressure relief mechanisms for any predetermined pressure from 50 to 1500 pounds per square inch. (with a 10% tolerance)

Each relief mechanism is set to its required pressure and sealed with a pin before leaving the MGM factory. The pin prevents tampering with adjustments. (Valve will automatically reseat after opening) Seat discs are made of synthetic material which will allow positive closure. All pipe threads are American Standard. Many body styles are provided in both 1/8" and 1/4" pipe sizes, angle or straight, with wither male or female threads. Straight bodies with threads on both ends have threads with center lines in alignment so pipe lines continue in a straight line. Angle bodies have one thread located in direct alignment with the relief mechanism and the other thread extending from the side at a 90 degree angle. All male pipe threads, in either 1/8" or 1/4" pipe sizes, have tapered seats to fit MGM Universal Fittings.

No. 213 SERIES MGM 1/4" RELIEF VALVES WITH OUTAGE TUBES MADE OF STAINLESS STEEL are identical with No. 210 Series MGM 1/4" Relief Valves having the same model letter designation (A, B, J or K) except that an outage tube (dip tube) has been added. See price sheet for information on outage tube length. These were designed especially for use with No. 211 MGM Sample Cylinders.

These are positive pressure relief mechanisms for any predetermined pressure from 25 to 1800 pounds per square inch, in increments of 25 pounds per square inch for valves with pressure ratings up to and including 800 pounds per square inch and in increments of 50 PSI for valves with pressure ratings about 800 PSI. Seat discs are made of synthetic material which will allow positive closure. Each relief mechanism is set to its required pressure and sealed with a pin before leaving the MGM factory. The pin prevents tampering with adjustments.
