These valves rapidly release air from the frontal service brake chambers for making a rapid brake. We offer quality guaranteed range of Quick Release Coupling designed without most precision as well as meticulousness. This extensive array is made-up of finest grade raw material procured from the prominent market vendors. We offer this array in several specifications and sizes. They are quality tested under diverse parameters to ensure their flawlessness. We offer them at most competitive prices in the market and they are the primary preference of our customers just like our array of Non Return Valve and Manifolds Valve.
A Quick Release Coupling (QRC) is a mechanical fitting used for rapid connection and disconnection of fluid lines.
It allows tool-free joining and separating of hoses or pipes.
It prevents fluid loss during disconnection with built-in check valves.
Pushing the male plug into the female socket depresses internal spring poppets to open the flow path.
A sliding sleeve locks stainless steel balls around the plug groove for a secure connection.
Pulling back the sleeve instantly releases the plug and seals both ends.
Used in pneumatic tool lines, hydraulic machinery, chemical transfer hoses, and gas lines.
Commonly applied in automotive repair, manufacturing plants, and agricultural equipment.
Ideal for applications requiring frequent hose changes.
Manufactured in Stainless Steel (SS316, SS304), Brass, and Carbon Steel.
Seals are available in NBR, Viton, or EPDM depending on fluid and temperature.
Durable metallic construction handles high working pressure and physical wear.
Enables rapid, tool-free connection and disconnection in seconds.
Automatic shut-off valves prevent fluid spillage and air inclusion.
Increases operational efficiency and safety in fluid transfer systems.
Keep locking sleeves and plugs clean of dirt, grit, and metallic shavings.
Inspect O-ring seals regularly for tears or hardening and replace if necessary.
Lubricate locking balls and sleeve mechanism occasionally for smooth operation.
Single Shut-Off couplings have a valve in the socket only (common in compressed air tools).
Double Shut-Off couplings have valves in both socket and plug, preventing fluid loss from both lines upon disconnect.
Straight-Through couplings have no internal valves, providing maximum flow with minimal pressure drop.
Connect under pressure (CUP) model couplings with pressure-eliminator valve designs can be specified.
Bleed system pressure before coupling or uncoupling if standard non-CUP models are used.
Selecting the correct valve type ensures operator safety during high-pressure hose handling.
Temperature limits depend on seal material: NBR (-20°C to +100°C), Viton (-20°C to +200°C), PTFE (-50°C to +230°C).
Compatible with hydraulic oils, compressed air, water, steam, fuels, and industrial chemicals.
Stainless steel 316 bodies provide optimal performance with corrosive fluids and outdoor exposure.
