Series 21 KA, 21 KF & 21 KB Automatic Single Shut-Off & Automatic Straight-Thru - Nominal Plug Bore 0.20"
Brand: Nycoil
The 91 Series is a variation of the 20 Series Couplers. The valve has been shortened in respect that the plug seals before the Coupler valve opens.
In spite of the short valve, the well-proven, single hand operation is retained as the ball-lock is replaced by a pin-lock. This extends the external diameter of the sleeve from 10 to 13 mm.
Series 21 KA & 21 KF are also available without a valve in a Straight-Thru design. For Straight-Thru Couplers, please change the part number from 21KA to 21KF when ordering.
Series 21 KB both the couplings and plugs are fitted with a valve. While both valves are opened, full flow is guaranteed as soon as the two are connected. The valves close when disconnected.
