Single Check Valve Coupling

Single Check Valve Couplings

They were originally used for connecting portable air tools and equipments to air lines. Hence , they are often referred to as Pneumatic Couplings. Originally they were available from 1/8″ to 1/2″ sizes, upto a pressure of 300 psi ( 21 kg/cm2). However, now they are available up to a 3″ size to meet new applications.

The Coupler should be installed on the supply end of the line to shut off the fluid supply when coupling is disconnected.

The adopter has no valving & upon disconnection exhausts the downstream media. Even in liquid lines, this would not be mechanically detrimental unless fluid loss would interface with a holding circuit or contaminates the area around it.

Fluids flows from coupler or adaptor

Features :

Interchangeable with standard industrial couplings

Anti rusting material for valve.

Minimum force to connect.

Wide variety of end connections.

Applications:

Air supply to small pneumatic tools /machines

Agriculture machinery

Air guns

General air service

Pneumatic pipings

Pneumatic Tools

Pneumatic servo control /systems

Workstations.

For Best Performance:

Use only with recommended media.

Use only with the suggested operating temperature. n Be sure to choose the appropriate type of packing material for your application.

Keep the coupler clean and free of dust .

Use a filter for fluid and air as foreign material may damage the coupler.

Be sure that the thread tape scraps do not enter the line.

Do not over tighten fittings as the threads may be damaged.

Do not hit, bend, or pull. This may cause leakage or damage.

When using with a vibrating or impact device, install a 30 c.m. length of intermediate hose between the device & the coupler.

Warning :

When using quick disconnect couplings, it is crucial to ensure that the media always flows from the coupler to the adapter for optimal performance and safety. Additionally, never attempt to connect or disconnect the coupler while it is under pressure, as this can lead to damage or hazardous fluid leaks. It is also important to avoid applying pulsative pressure to the coupler when it is disconnected, as this can compromise the integrity of the system and potentially cause malfunctions. Following these guidelines ensures safe and efficient operation of the coupling system.
