Straight Through Valve Qrc
The Straight Through Valve Quick Release Coupling (QRC) operates on a push-and-pull principle for hydraulic pipework. When the adaptor is inserted into the coupler, it is securely held by a self-locking mechanism that prevents leaks. The Stainless Steel Straight Through Valve QRC is highly resistant to corrosion and performs well in both organic and inorganic compounds. It can also withstand harsh environmental conditions. These couplings are commonly used to transfer fluid over long distances, including underwater applications spanning several kilometers.

QUALITY CONTROL
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.
