Introducing DDA’S Feed Block Vent Kit
Feed Block Vent Kit removes the risk of high-pressure fluids when performing maintenance above the holding valve on the feed system hoses.Known Problem
When the machine has been shut down and locked out there is always a potential risk of high-pressure fluid in the feed circuit. There is no easy way to remove/vent the residual pressure without removing/overriding the holding/ counterbalance valve.DDA’s Solution
Before commencing any work on the feed system, install a Feed Block Vent Kit inline and above the holding valve. ?Connect test hose to tank before connecting to the vent block. Then connect the other side of test hose to the vent block to ensure all stored high-pressure fluid is vented to tank. ?A Stauff test point is supplied with the block.
