The Nitto Kohki Full-Blow SH quick coupler socket, designed for hoses with clamp fastening, ensures full air and inert gas flow, optimizing the performance of industrial pneumatic systems. Its safety lock with pressure relief enables safe system decompression before disconnection, increasing operational safety and efficiency. Compatible with the Nitto line, it offers versatility for manufacturing and automation applications.
The Full-Blow Cupla pneumatic couplers from Nitto Kohki feature a body manufactured from aluminum alloy, ensuring light weight and mechanical strength. They are available with threads and hose nipples in 1/4", 3/8" and 1/2" sizes.
The SN Type version is compatible with polyurethane hoses in the following diameters:
The maximum working pressure is 1.5 MPa, equivalent to 15 kgf/cm², 15 bar or 218 PSI, ensuring excellent performance in industrial applications with high pressure demands.
The sealing material used is nitrile rubber (NBR), designated as NBR (SG), operating safely within a temperature range of -20°C to +60°C. This is the standard sealing material supplied with the product.
Socket for use with hose and clamp fastening.
Interchangeable with the entire Nitto line (PH, PF, PM, PN, PAH, SH, SF, SM, SN).
It offers a major advantage through its full compressed-air passage and safety lock, which can be used to relieve system pressure before uncoupling.
Specifications:
• Application: air and inert gas;
• Body composition: aluminum;
Operation with the valve open or closed
The valve may be open or closed when the coupler is connected.
After connection to the plug, slide sleeve B to open the valve. Full flow is obtained this way.
Slide sleeve B back to the original position to block the flow.
The exclusive fully open gate-type valve mechanism provides low pressure loss and high flow, reducing the required source air volume.
-Flow is increased by up to 40% compared with HI CUPLA.
-During connection and disconnection, the valve is closed, allowing connection/disconnection with zero line pressure.
-When the socket sleeve returns to its original position, the purge mechanism releases residual air pressure in the coupler, eliminating unpleasant popping noise and hose whip movement during disconnection.
-The separation-prevention mechanism avoids accidental CUPLA connection, ensuring safe operation.
-The valve can be opened and closed while the socket and plug are connected.
-Weight is reduced by 30 to 45% compared with conventional Cuplas.
Note: Direct installation of the Full-Blow Cupla on percussive and vibrating tools should be avoided. The exclusive fully open gate-type valve mechanism provides low pressure loss and a high flow rate, reducing the required source air volume.
