The Beck Valve is connected to the blowpipe-stock, using a tapered universal fitting that does away with the need for hemp. The valve gives an
excellent delivery of air, and unlike other valves it is not dependant on a back pressure of air for closure.
Due to its shape, the valve also acts as a spit trap. Condensation is caused when blowing air into the bag. The condensation collects around the wall
of the stock and gets trapped between the wall of the stock and the tube of the blowpipe valve. All you need to do is remove your blowpipe, turn the
blowpipe stock upside-down and pour out the spit. Very simple and very effective.
How to install: The Beck Valve is pushed into the stock, no need to fit with hemp. The rubber flaps prevent it from slipping out of the stock.
