Product Description

Features:

• Both the socket and plug of this twin valve coupling incorporate a shutoff valve. The moment the socket and plug are disconnected, thevalves on the socket and plug sides contact the mating seat sections to completely seal the socket and plug sides.
• The body is made of chromium-molybdenum steel and hardened to ensure high durability and a high resistance to abrasion.
• This series has been designed for use under high pressure and is highly resistant to vibration and a high resistance to abrasion.
• Due to low pressure loss, this series is ideally suited for highly pressurized oil and gas pipes.

Explanation:

When disconnecting
When the sleeve of the socket is moved to the socket side, the steel ball can move freely in the outer circumferential direction. The socket by the reaction forces of the socket and plug valve springs. The moment the plug is disconnected, the valves on the socket and plug sides contact the mating seat sections to stop the fluid from flowing.

When connecting
If the plug is inserted while the sleeve remains on the socket side, the sleeve is returned to its former position by the force of the sleeve spring and the steel ball locks in place to ensure connection. At this time, the valve on the socket side and that on the plug side push against each other to open the passage and allow fluid to flow. The O-ring completely prevents fluid leakage.
