QUALITY CONTORL
Each AVLOK Coupling manufactured goes through stringent quality control, right from the procurement of raw material upto final stage.
PRECAUTION :
- Avoid connecting or disconnecting a coupling under pressure.
- Residual pressure in a coupling may make it difficult to connect. In such a case do not strike the valve end to depressurize it.
- Improper selection of seal rubber may cause leakage.
- Dust or flaws in the seal may cause leakage.
- Improper selection or improper use of the products can cause personal injury and property damage.
FEATURES :
Operation: The sliding sleeve on the coupler is pulled back, the adaptor is inserted then the sleeve is pushed forward to make the connection. The seal is made by poppet valves in each component which close during the disconnection cycle.
