  • Successfully connected - disconnected 100,000 times in tests.
  • Tempered for extremely high wear resistance.
  • Twisting of the hose is automatically corrected by a bearing when connected.
  • Valve at the socket side is automatically opened closed by the disconnection and connection operation.
  • Hasolon couplings work on simple ‘push & pull' principal. The adopter when pushed into the coupler is securely held by the self locking arrangements, resulting in a positive and leak-proof connection. This action simultaneously opens the valve and the fluid flow starts. To disconnect, pull back the sleeve of the coupler, the adaptor rejects out and the valve shuts off automatically.

Type-SC Single check valve (one way shut off) quick release coupligs
Type-SC is most popular type coupler used to connect air piping in factories and used to connect air tools with hoses etc. Bot socket and plug have house use and screw use advantages. there is also a variety of other types. The types 20, 30, 40 and Types 400 and 600 are completely interchangeable. With one check valve built into the coupling only whereas plug do not have any check any check valves. Can be advantageous used where one side of flow system needs to be sealed on disconnection. Dimension & weight table

Type-ST Straight through quick release couplings
This is double path open type, coupler which does not have a valve mechanism at either the socket mot the plug. It is used in piping systems in which blocking of the fluids when disconnected is unnecessary and closure of lines is achieved by back up valves. Permitfull flow capability due to their smooth and accurately finished. Dimension & weight table

Type-DC Double check valve (Double shut off) quick release couplings
Type - DC Couplers are having Built in Self sealing valves on plug and socket ends that both socket and plugs are sealed instantly on disconnection. Dimension & weight table
 

Connection and Disconnection

In the case of connection, the balls in the socket become free when the sleeve is slid in the direction of the arrow. 1 When the sleeve 3 is released after the plug 2 has been fully inserted in to the socket with the sleeve 3 still held back, the sleeve is returned to its origional position by a spring, and balls enter the ball grooves of the plug, completing.
In the case of disconnection, the balls become free when the seleeve is slid in the direction of the arrow 1, permitting easy separation of plug and socket. 

 

Coupler Handling Precautions
1. Avoid connecting and disconnecting the coupler when pressure is applied to preclude possible accident. Connection and disconnection of TYPE-SC Coupler is possible, however when pressure is applied.
 
2. Coupler has been designed to insure complete safety, however avoid subjecting it to shock. Handle with care when connecting and disconnecting in Piping applications.
 
3. Remove foreign matter from the fluid with a filter beforehand, If foreign matter is mixed in the fluid, operation of the internal valve will be adversely effected causing leakage.
 
4. Do not weld the coupler directly to panels and fixtures, This damages the internal seal causing leakage and imperfect flow.
 
5. When disconnecting the coupler in dusty and sandy locations, always use the specified dust cap.
 
6. Never tap the valve section with a hammer, etc, to bleed residual pressure.
