We use latest technology and comprehensive quality control systems in designing and manufacturing wide range of Quick Release Coupling. Designed for reliable performance, our entire range is fabricated from qualitative raw material for ultimate durability and strength. These corrosion resistant coupling come with single & double shut off valves for avoiding leakage.
QRC type coupling work on Push and Pull principle. When the Adaptor is pushed to the coupler, its is accurately held by the self locking arrangement resulting in a positive & leak proof connection. This action simultaneously opens the valve & fluid flow starts. To disconnect, pull back the sleeve of the coupler, the Adaptor ejects out and the valves shut off automatically. Valves are provided in type one way sealing & two way sealing.
|Material of Construction – As Per Standards|
|Sizes are mainly from 1/8 inch up to 2 inch used by various industries & having end connections like pipe thread male / female, hose shank etc.|
|There are three types of Quick Couplings mainly used as follows|
|1. Through Bore QRC – Make - “VE-Lock – T”|
2. Single check valve QRC (One way shut off type) – Make - “VE-Lock – V”
3. Double check vslve qrc (two way type ) - MAKE - " VELOCK - DC "
|Quick release coupling - through bore type|
Bore type quick release couplings have no check valves. These are ideal for maximum flow application. Their smooth, open bore offers the lowest pressure drop of any quick disconnected couplings and allows them to be through cleaned. Since there is no valves, fluid flow should be shut off before the coupling is disconnected.
Where quickly detachable and rotatable connections are needed
Also used where regulation and closure of line is achieved by back up valves
|Quick release coupling - single check valve type|
One way sealing with one check valve build in to coupler only, where as plug do not have any check valve.
These couplings are used extensively when it is important to minimize fluid loss upon disconnection.
|Quick release coupling - double check valve type|
Double check valve type qrc having in build check valves in both part as coupler & adaptor this types of qrc applied for the systems where the minimum fluid loss requirements during disconnection. In double check valve type qrc,we refer iso 7241 - b standards qrc as general purpose & iso 7241 -a type for high pressure application only.
used extensively when it is important to minimize fluid loss upon disconnection.
