Quick connect coupling Purge HI Cupla PV-20SM, brass - Nitto Kohki 316102400

Purge HI Cupla releases the pressure trapped in the line in a controlled way as the coupling is broken. The plug comes free more calmly and the disconnected hose stays under control.

• Pressure is bled off during disconnection instead of being released all at once
• Sockets in brass and in zinc plated brass, plugs in steel
• NBR seal across the whole series
• The PV and PVR ranges cover several connection and material variants
• Connect and disconnect by hand, with no tools

Operating principle

• Air line coupling with built-in residual air pressure release function.
• Connection can be made smoothly regardless of the existing pressure inside the socket.
• Push-to-connect operation. Easy one-hand operation.
• Built-in separation prevention mechanism prevents accidental disconnection of CUPLA, ensuring safe operation.
• Upon completion of sleeve locking the valve will open to supply air.
• When the sleeve is turned back to its original position, the valve is closed and purges residual air pressure in the plug without unpleasant popping noise and hose whip motion on disconnection.
• Even after connection, valve opening/closing control is possible.
• Flow rate increases by approximately 20 percent over that of HI CUPLA Model 400SM.

Series comparison

Choose PURGE HI CUPLA where an air line has to be connected regardless of the pressure standing inside the socket and the residual air pressure in the plug must be released before separation. It is one-way shut-off like HI CUPLA BL, NUT CUPLA, LOCK CUPLA 200, HI CUPLA Two Way Type, ROTARY LINE CUPLA and ROTARY PLUG: take the PVR Type for lines up to 1.5 MPa {15 kgf/cm2} and the lever operated PV Type where 1.0 MPa {10 kgf/cm2} is enough, as with PURGE LINE CUPLA and TWIST PLUG. If both sides of the line have to close, COMPACT ZEROSPILL CUPLA with its two-way shut-off at 1.0 MPa {10 kgf/cm2} is the alternative.

Applications

• Lines that hold residual pressure and are disconnected regularly
• Workstations where connected equipment is changed often
• Plant maintenance where individual branches are uncoupled
• Test rigs with changing pipework
