unique design gives several advantages
Unique Design Gives Several Advantages
  • To Connect (Push and turn)
    • It’s coupled
    • Full flow
  • To disconnect (Turn and pull)
    • It’s released
    • No spillage
  • Easy to handle

Push and turn – free flow.

Turn and pull – closed.

  • Time saving

No need to drain hoses or pipe systems.

  • Economical

No loss or spillage of liquids of connection or disconnection.

  • Safe

The valve cannot be opened until the unit is coupled.

  • Environmentally friendly

Accidental spillage elminated.

  • Reliability

No loss or spillage of liquids at connection or disconnection.




Compatibility with other existing brands according to NATO STANAG 3756 and ATOFINA SGM 2049.TUY.C.


Currently inventoried by Dixon in Stainless Steel , Aluminum, Gun Metal (Brass)

in sizes 3/4 thru 6”.

Stainless Steel


All wetted parts in Stainless Steel and Hastelloy.

Typical applications:

Chemical industry

Pharmaceutical industry

Waste transfer

All wetted parts in Aluminum and Stainless Steel.

Typical applications:

Military use

Petrol handling

Aviation fuel



All wetted parts in Brass/Gunmetal and Stainless Steel.

Typical applications:

Marine refueling

Petrol handling

Tanker loading

All wetted parts in Hastelloy.

Typical applications:

Hydrochloric acid


PTFE (Teflon) bearing between piston shaft and piston guide eliminates seizure.

Female NPT Threading

Inner parts made of Hastelloy C-276 and 316 Stainless Steel for longer life

Conical valve seat to eliminate the risk of “piston blow-out” in the event of extreme pressure.

Weather resistant, protective bumper ring. Electrically conductive.

Hastelloy C-276 rollers on Stainless Steel shaft to eliminate seizure potential.

Riveted piston pin to minimize risk of failure under high pressure conditions

PTFE (Teflon) bearing between drive plate & piston guide eliminates seizure.

C-276 Hastelloy shaft journal embedded in PTFE (Teflon) eliminates seizure.

Stainless Steel ball bearings

Female NPT Threading


No other manufacturer utilizes Hastelloy C-276 for chemical resistance, and longevity of product life, as does Mann Tek.
