Quick Release Couplings

We at vardhman bearings are manufacturers and exporters of all type of quick release couplings , quick couplings , cam locks , new series of quick release couplings , stainless steel couplings , brass quick release coupling , aluminum quick release coupling , stainless steel 303 , 304 , 316 , 202 , 201 , 210 , 212 , 202 grade of quick release couplings , carbon steel quick release couplings , QRC ,
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.
  • Quick connect / Release Couplings eliminate valves and screw on fittings in many pneumatic, hydraulic and chemical systems.
  • Permits easy, safe, quick & reliable connections between delivery lines, pressure hoses etc.
  • Connection disconnection of fluid systems is as easy as plugging in an electric gadget.

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.
Application :-
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
Application: -
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.
Application: -
used extensively when it is important to minimize fluid loss upon disconnection.

Quick couplings are devices which permits easy, immediate connections and seperation of fluid and pneumatic lines. When installed in a system quick couplings saves time by liminating the necessity to close valves, bleed the system, recharge with fluid and purge entrapped air whenever an accessory is being replaced. QUICK COUPLINGS are widely used in industrial, process, farm, military amd aerospace applications. QUICK COUPLINGS can be used in System to help align components and the several feature helps prevent twisting of hose assemblies. These couplings are not intended to be used as several joints in applications, where subjected to constant rotation.

Camlock Couplings
A Camlock coupling is in fact, a means of quick engaging of disengaging a hose connection from a system requiring transfer of fluid or gas. It consists of a COUPLER with cam arms and a slip in ADAPTOR. In order to connect the Arm of the coupler need to be lifted and the adaptor slipped into the coupler. The handle are then pressed down with normal hand pressure for a leak proof connection.
TYPE :- 
The Coupler & Adaptors are available in different configurations:
  • With male and female threads (BSP,BSPT, or NPT)
  • With hose shanks
  • With flanges or weld ends.

Brand Promotion For Buyers
  • The Industries has found that , whenever there is an excess orders then the owned manufacturing capacity then the buyers would offload their work to the approved vendors & ask them to supply with out marking & with their brand logo on each items.
  • Vardhman has developed those spare capacity to serve such buyers who can offload their work to us we can manufacture them as per the drawings,part diamensions, standards & supply them without marking or marked their logo on each items.
